# nx2navi.ini: settings for nx2navi.exe. Copy this file to nx2navi.ini next to nx2navi.exe and remove the '#' of a line to change it.
# Each line shows the default; on a Steam Deck the device profile ([display]) changes a few of them. A NX2NAVI_*
# environment variable of the same name (NX2NAVI_FPS_LIMIT for fps_limit) overrides the file. Keys are case-insensitive;
# '#' and ';' start a comment; [sections] only group lines.
# Only the keys in this file are settings. A line with any other key does nothing: the game's log names it at the
# start ("no setting of this version") and the settings menu (F1) shows it in its bottom row.
# Updates and rebuilds of the game never rewrite nx2navi.ini; the settings menu changes only the lines of the settings
# it changes and keeps every other line as it is.

[frame rate]
# Frame rate limit: 30, 40, 45, 60, 90, 120, 144, any whole rate from 30 to 240, display (the refresh rate of the
# window's monitor, at most 240) or unlimited (as fast as the PC goes, at most 240 frames of the game a second). A
# higher rate gives 240: far above it the game's own code fails (its quick menu crashed at 700 fps). Above 60
# is experimental and needs realtime = 1. Changes while the game runs take effect at once.
# With mailbox or fifo presentation (vk_present, the default) a frame reaches the screen at a vertical blank, so a limit
# that does not divide the monitor's refresh rate keeps each frame on screen for a different number of refreshes. On a
# 320 Hz monitor 80, 64, 40 and 32 divide it and 90 does not: 90 fps alternates 3 and 4 refreshes per frame, which reads
# as judder while the frame counter still shows 90. Likewise on 240 Hz 60, 48 and 40 divide it and on 144 Hz 72, 48 and
# 36 do, while 60 does not. vk_present = immediate shows a frame as soon as it is presented, without this quantisation,
# at the cost of tearing. A monitor running with variable refresh (FreeSync, G-Sync) follows the frames instead, so
# there any limit inside its range is even.
# With frame generation on (framegen, [display]) the limit still counts the frames the game draws, and the generated
# frames come on top: 60 at 4x is 60 drawn and 240 on screen. Only display counts the frames on screen, so there the
# game draws the monitor's rate divided by the multiplier.
# fps_limit = 60
# Where RivaTuner Statistics Server is installed and running, the limit goes into its profile for the game's
# executable and RTSS does the limiting instead of the game; closing the game puts back what the profile held.
# Changing that profile needs the game run as administrator (RTSS keeps its profiles under Program Files); without
# it, or with frame generation on, the game limits by itself, and also when RTSS's own frame counter shows the game
# well past the limit (RTSS then hooks the game without holding it back). rtss = 0 always leaves it to the game.
# rtss = 1
# 1: asks RTSS's EnumProfiles whether the game's profile exists, instead of looking for its file. EnumProfiles crashes
# the game (RTSS keeps a pointer of the game's in 32 bits); only for testing an RTSS that fixed it.

# highfps_fix = 1
# Above 60 fps the game's physics solved contacts and friction in fewer steps a second than at 60, and in none at all
# in a frame shorter than 1/240 s, so things standing on moving platforms were left behind. 1 rounds the step count
# up instead; 0 is the game's own count. 2 also gives every frame at least the 4 steps of a 60 fps frame, which costs
# more physics time above 60 fps (576 steps a second at 144 fps, 960 at 240, against about 288 and 240 with 1) and is
# a candidate fix for Link left behind on the Deku Tree's floating platform. Read at start.
# physics_steps = 1
# The number in the window that shows a pick-up (a rupee) counts up by whole steps a frame, and above 60 fps the game

# it count at least one a frame; 0 is the game's own count.
# pickup_count = 1
# Water surfaces and the springy floors (the Deku Tree's webs) are simulated in fixed steps of 1/60 s, as many as the
# frame's time holds, and the game dropped the rest: above 60 fps every frame ran none, so they stood still under Link.
# 1 keeps the rest for the next frame, 60 steps a second at any frame rate; 0 is the game's own count. Read at start.
# water_steps = 1
# Above 60 fps the game handed its sound system a fraction of a frame each frame, which was reported to keep sounds
# held after an area unloaded until new sounds and then the music went silent. 1 runs the sound system 60 times a
# second with whole frames while the frame rate is above 60; 0 is the game's own step. Read at start.
# sound_steps = 1
# Above 100 fps the game kept only a tenth of a moving floor's speed for whoever stood on it, so Link was left behind
# on moving platforms (the Deku Tree's floating one). 1 makes the floor carry him as at 60 fps at any frame rate; 0 is
# the game's own cut. Read at start; needs game code generated with this release.
# floor_carry = 1
# A movie's narration and fades follow the picture on screen: 1 counts their time from the shown picture's
# timestamp, so they stay with it at any frame rate (with movie_fps = 0 too) and wait when the picture stalls; 0 counts
# the game's redraws, as before, which keeps them with the music when the picture stalls. Read at start; needs game
# code generated with this release.
# movie_pts = 1
# The step the game is given each frame: 1 keeps it steady (the same value from frame to frame while the frame rate
# holds, exactly one 60 Hz frame at a 60 fps limit) and makes up for a late frame over the next second; 0 is the mean
# of the last five frame times, which changes with every frame.

# of latency, and can show a dark or flickering frame now and then: the other thread reads vertex and buffer memory
# the game has sometimes rewritten by then.
# replay_async = 0
# EXPERIMENTAL. Record the large groups of draws of a submission on this many replay worker threads beside the
# submitting one: auto or 0 to 16. Default: auto, half the CPU's physical cores less one (2 on 6 cores, 3 on 8, 5 on
# 12, at most 6), none on four cores or fewer and none on AMD's driver for RX 6000 and older Radeon cards, where a

# added its bloom, applied its exposure and tonemapped it. 1: on the scene's own light, before the bloom chain and the
# tonemap, as these upscalers are made for; the bloom, the lens flares and the tonemap then work on the upscaler's
# picture, drawn at the picture's size when the scene is smaller. Frames without the bloom (menus) stay as with 0.

# dlss_prebloom = 0
# Per-object motion vectors for DLSS: characters, animals and moving objects get their own motion instead of the

# dlaa_objmv = 1
# Motion vectors of Link's own for DLSS, FSR 3.1 and frame generation (game 1.1.1): Link and the equipment attached to him are
# drawn a second time with last frame's pose, so fast turns, attacks and jumps move by their real motion instead of an
# estimate from colour and depth. 1, the default; 0: the estimate, as before 0.10.0. It reads the player's equipment
# from the game's memory at every submission. Read at start.
# motion_guard_degrees (35, 45 or 60, the default): a part that turns more than this in one frame is checked against
# last frame's depth before its vector is written.
# selective_motion = 1
# Motion vectors of their own for every other skinned character (game 1.1.1): people, animals and enemies are drawn a
# second time with last frame's pose too, so DLSS, FSR 3.1 and frame generation follow them as they move instead of
# smearing them along the camera's motion. A character's draw is matched with last frame's by its mesh and shaders;
# where the match is in doubt (it just appeared, another one of the same model appeared or left) it keeps the camera's
# motion for a few frames. 1, the default; 0: the camera's motion for all of them, as before. Nothing runs without
# DLSS or FSR 3.1. The "selective motion" log line counts the skinned draws and why some kept the camera's motion.
# Read at start.
# skin_motion = 1
# Characters' trails: where a character, animal or held item moves without motion vectors of its own (all of them with
# dlaa_objmv = 0), DLSS can drag a faint copy of it. The G-buffer marks those objects; on them and where they were the
# frame before, DLSS is told to favour the current frame by this percentage (0, 35, 65 or 100; 0 off). Higher removes
# more of the trails and leaves those edges a little less smooth. Changes while the game runs take effect at once.

# Anti-aliasing of the 3D picture: game (the game's own SMAA, as on the console), off, fxaa, smaa (SMAA at its Ultra
# preset in the game's place) or taa (DLSS or FSR at full size: dlaa = 1 with dlss = dlaa, which the menu's
# Anti-aliasing row sets with it, and the game's SMAA). With DLSS or FSR on (dlaa = 1, any mode) their TAA always runs,
# and game, off, fxaa or smaa runs along with it: off leaves the edges to the TAA alone. Changes while the game runs
# take effect at once.
# aa = game
# The FXAA switch of the game this runtime was first written for; Ocarina has no such pass, so it changes nothing here
# (aa above is the setting).

# Frame generation: off, fsr3 (AMD FSR 3.1 on any GPU where amd_fidelityfx_vk.dll loads, so not on Linux: one generated
# frame between every two the game draws, the HUD kept out of it) or dlss (NVIDIA DLSS Frame Generation on GeForce RTX
# 40 and 50 GPUs, paced with Reflex; it needs nx2navi_dlssg.dll and NVIDIA Streamline's files next to the executable,
# which the setup puts there). Both run with any upscaling: with DLSS or FSR 3.1 (dlaa = 1) they take its depth and
# motion vectors, and without one (dlaa = 0) the same ones made for them alone, with no jitter (the log's "dlaa: frame
# generation runs" line says which). While frame generation runs, fps_limit
# counts the frames the game draws and the screen shows that times the multiplier (2 for fsr3); fps_limit = display
# alone holds the screen to the monitor's rate and the game to that rate divided by the multiplier.
# fsr3 takes effect at once, dlss (on or off) at the next start.
# framegen = off
# On Linux dlss runs through NVIDIA's NGX itself, without Streamline: it needs dlaa = 1 with DLSS when the game starts
# (it keeps running when dlaa is switched off later) and NVIDIA's libnvidia-ngx-dlssg.so.<version> (from NVIDIA's DLSS SDK repository) beside the game, then switches at
# once, and its multiplier is fg_mult: 2 to 6 (above 2 needs an RTX 50 GPU) or dynamic, which generates only the frames
# needed to reach the display's refresh rate at the rate the game draws. framegen_multiplier is not used there.
# fg_mult = 2
# DLSS frame generation's multiplier: the frames on screen for each frame the game draws, 2, 3 or 4 (one, two or three
# generated). 2 needs an RTX 40 GPU or newer, 3 and 4 an RTX 50 and a current driver. A value above what the GPU and
# driver allow (Streamline reports it) is lowered to that, with a line in the log; the menu offers only what they allow.
# Each step adds a little latency, and a display shows no more than its refresh rate. Changes while the game runs
# take effect at once.
# framegen_multiplier = 2
# Low latency without frame generation: 0 off, 1 on, 2 on with boost (NVIDIA's: the GPU keeps a high clock; on AMD 2
# is 1). The graphics driver holds each frame's start, so the game reads the controller as late as the picture allows
# and no finished picture waits for its turn: NVIDIA's low-latency mode (VK_NV_low_latency2) or AMD's Anti-Lag
# (VK_AMD_anti_lag), whichever the driver has. On a driver with neither the setting does nothing. While it is on the
# driver holds the game to fps_limit, in place of the game's own limiter and of RivaTuner Statistics Server (rtss).
# With framegen = dlss on Windows, DLSS Frame Generation's own low latency is used and this setting is not; with
# framegen = fsr3 it runs on AMD GPUs and is off on NVIDIA ones while frames are generated. Turning it on takes effect
# at the next start: a run that starts with 0 leaves the driver's mode off the graphics device altogether. In a run
# that started with it on, changes take effect at once.

# start. hdr_peak_nits is your display's peak, hdr_game_nits the picture's white (paper white, 203 is the HDR
# reference) and hdr_ui_nits the HUD's and the menu's. The settings of the look of earlier versions
# (hdr_tonemap, hdr_exposure, hdr_gamma and the rest) are read by nothing now and do no harm.

# bytes that went back ("over-default"). Raising it costs a copy per such target and wait.
# wb_fence_limit = 65536
# Log kernel services that block longer than this many ms, with the service number (0: off). A stalled frame shows up as
# time in the replay; this says whether the guest was waiting in a service, and which one.
# svc_slow_ms = 0
# 1: every signalled event and every thread that ends wakes all the game threads that wait for any event, as before;
# each takes one of the game's virtual cores to find that its own event is not the one, often from a thread that was
# working. 0 (default): only the threads that wait for that event or thread are woken. With trace = sched the
# "sched:" line counts both ("signals woke ..., left ... asleep").
# sync_wake_all = 0
# 1 (default): a thread of its own writes the log lines, to the log file and the console, so a write that stalls (a
# busy disk, a virus scanner, a console that scrolls) no longer holds the thread that logged, which is often the one
# that draws the frame. It writes the lines of a quarter of a second together, sooner when many are waiting, so the
# log file and the console are up to that much behind the game. A crash, a fatal error and the end of the game write
# out what is still queued first; a game that is ended from outside (Task Manager) loses those last lines. 0: each
# line is written at once by the thread that logs it, as before. Either way a "log: ... writes of the log took over
# 2 ms" line counts the slow writes and says whose time they took.
# log_async = 1
# 1: the frame-time summary also splits the replay by op kind (draw, bind, transfer), which says where a stalled frame
# went. The clock reads cost a fraction of a millisecond a frame, so it is off by default.
# replay_time = 0
# A frame whose texture work on the render thread (new textures, uploads, upload submits) takes at least this many ms
# gets a "texup:" line in the log that splits it: creation, staging, storage copy, ASTC recording, scratch buffers and
# new device memory (up to 400 lines; 0: none; 16 catches the area-change hitches).
# texup_log_ms = 0
# 1: the frame-time summary also lists the locks the replay waited for, by the code that asked (addresses; the line's
# "ref" is perf_lock_timing_here, which the link map names), the recorder's waits, and the texture lock's holds over
# 1 ms. Off by default.
# lock_time = 0
# Texture entries the bindless texture pool may create in one refresh (images and their uploads); the rest wait for
# the next refresh and show their stand-in until then. Lower spreads streaming over more frames (smaller hitches, a
# frame or two of pop-in); higher loads sooner.
# pool_create_budget = 16
# The refresh runs before every draw that samples the pool, so the budget above holds per draw. Once a frame's
# refreshes have taken this many ms, they create nothing more until the next frame (the first refresh of each frame
# keeps its budget): an area load then spreads over several frames with stand-ins instead of holding one frame for
# 200-400 ms. 0: no limit.
# pool_create_ms = 6
# An area load is told from streaming by the number of textures still to make: at this many or more, the two limits
# above give way (a frame may take pool_load_ms for them) and the picture before the load stays on screen until the
# area's textures are there, instead of showing the ground and the walls black for the first seconds. 0: never.
# pool_load_backlog = 512
# pool_load_ms = 50
# Written storage-buffer ranges up to this size in MiB (1 to 256) go back to game memory as a merge, in 4 MiB pieces:
# copied within video memory and only the words that changed written over PCIe. Larger ones are copied back whole at
# the end of every submission. Raising it from 4 to 16 took a 5.5 MiB range off the plain copies (about 46 MiB a frame
# in the field), and 32 the 4-15 MiB ranges of Kokiri Forest.
# wb_merge_max = 32
# 1: pages a VRAM mirror wrote back to game memory are not copied up into it again, as it already holds them (a write by
# the game still is). Outdoors this removed about 57 MiB of copies a frame. 0: they are copied up again.
# wb_no_reup = 1
# 1: finds out who reads what the GPU wrote back into guest memory. The 2 MiB regions inside a range just written back
# are made inaccessible until their first read or write, which is logged with its instruction ("mem: write-back
# probe"). The bytes are there all along; the probe only watches, at the cost of the faults it takes.
# wb_probe = 0
# The wait after each frame's first GPU submission. 1 (default): it ends when the video card has run the submission
# and the results the game reads next are in its memory (the last frame's visibility counts above all); what the card
# wrote besides goes back to the game's memory in a submission of its own, behind the wait. 0: the game waits until
# everything before it has reached its memory, about 0.7 ms more of every frame in the open. 3: the wait ends as soon
# as the card has run the submission, without the visibility counts: the game then reads counts that may be a frame
# old, and lit things near the camera can lose their light for single frames. With shadow storage (Linux, Wine) 1
# and 3 change nothing; 2 forces 1 there as well, for tests.
# wb_split = 1
# 1: what the game's shaders write into its memory is copied back from the video card once, and after that only when
# the game's CPU code touches it (most of it never is: 66 MiB a frame in Hyrule Field), for about a third more frames
# a second in open areas. 0: copied back at the end of every GPU submission, as in 0.7.0.
# Default: 1 on Windows, except 0 on AMD graphics cards (AMD's own driver), where two reports had the game end in play
# with it on and the cause is not found: set 1 there to try it, and back to 0 if the game ends in a fight (the log's
# "mem: lazy write-back" line says which is in effect and why). 0 elsewhere. With shadow storage (Linux, Wine) it
# stays off whatever is set.
# wb_lazy = 1
# With wb_lazy, off by default: with it on the graphics device was lost shortly after some save loads (about one load
# in three of a save in Hyrule Field at night on one card), and not once in 15 loads with it off; the cause is open.
# 1: when the game's CPU code touches such memory, only the 64 KiB around the place it touched are copied
# back and kept up to date from then on; the rest of that buffer stays on the video card. The game reads a few words
# at the start of buffers of several MiB about twice a second. 0: the whole buffer comes back and everything near it
# is copied back every frame for up to 32 seconds, as before (a tenth fewer frames a second in a village).
# wb_lazy_chunk = 0
# Barriers between the game's draw passes and compute dispatches. 1: only where the game itself asks for one, or where
# the work changes between drawing and compute; this takes about a tenth off the graphics card's time for a frame.
# 0: a full barrier before every pass and every dispatch. Default: 1 on NVIDIA graphics cards, 0 on all others, where it
# has not been tried: set 1 there to try it, and back to 0 if the picture shows faults.
# barrier_game = 1
# Mesh draws whose count the graphics card computes: 1 (default) prepares the counts of a run of such draws at its
# first one, so their draw pass is not ended and begun again at each of them (about 40 passes fewer a frame in a
# village). 0: each such draw ends its pass and prepares its own count, as before.
# mesh_ahead = 1
# Graphics cards without mesh shaders (GTX 10 series, RX 500 and 5000 series, many integrated ones): the game's mesh
# draws, most of the world, are computed in compute passes and drawn as ordinary triangles. auto (default) does that
# only on such a card; 1 does it on every card (for testing: it is slower than mesh shaders); 0 never, and such a
# card then draws no world.
# mesh_fallback = auto
# Video memory in MB for what those compute passes hand to the draws. A draw that needs more loses the geometry that
# does not fit, and the log says so.
# mesh_fallback_mb = 128
# Threads that prepare those compute passes for the mesh programs a place uses, the first time each is drawn (until
# then its draws are left out). auto (default): one for each 4 logical processors, 1 to 4.
# mesh_fallback_workers = auto
# Windows, 1 (experimental): the game's heap is committed a 64 KiB run at a time where it is first used, instead of
# all of it when the game sizes it. Windows counts committed memory against RAM plus the page file whether it is used
# or not, and in Castle Town after Hyrule Field about 3.4 of the heap's 6.8 GiB had never been used. 0: committed up
# front. Linux commits pages on first use anyway. With 1, a PC whose commit is used up ends the game at the moment a
# heap page is first used, in the middle of play, where with 0 it would not have started.
# heap_lazy = 0
# Linux, shadow storage: 1 clears the write watch's protection of a range in one call before the GPU's bytes are copied
# back into the game's memory, instead of taking a fault at the first store into each page.
# shadow_bulk_write = 0
# 1: the game's flushes of mirrored memory are copied into the mirrors even where the write watch already sees every
# page the game wrote; 0 (default) copies only the written pages there, which saved 47-57 MiB of copies a frame in
# Kokiri Forest.
# flush_upload = 0
# For measuring: only mirrors of the game's memory pools up to this many KiB send what shaders write through the
# device address table to game memory as well; larger mirrors keep it in video memory and are not evicted. On PCIe 3.0
# those second writes cost about 3 ms of GPU time a frame. 0 (default): every mirror sends them. A pool that needs them
# and is left without shows as foliage stretched into columns or flickering.
# gpa_twin_max_kb = 0
# 1 (default): shaders that follow the game's pointers read a memory pool's new copy in video memory only once that
# copy has been filled; until then they read the game's own memory. 0: they read the new copy at once, as up to 0.9.2,
# where a card over its video memory budget could lose the device at an area load (a GPU read fault at the first byte
# of the new copy).
# gpa_late = 1
