# 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, once RTSS is seen holding the game to it; closing the game
# puts back what the profile held, and after a crash or a kill the next start does, unless it has rtss = 0
# (rtss-profile.txt next to the game keeps what it held). Changing that profile needs the game run as administrator
# (RTSS keeps its profiles under Program Files). Without it the game limits by itself, as it does with frame generation
# on (RTSS would count the generated frames), while the window is minimised, and for the rest of the run when RTSS's
# own frame counter shows the game past the limit (RTSS then hooks the game without holding it back) or RTSS is not
# seen holding the game within 30 s; the game paces movies itself. With low latency on, the driver holds the limit.
# rtss = 0 always leaves it to the game. With rtss = 0,
# frame generation or low latency, a limit set in RTSS itself (its global profile or the game's, a frame time limit or
# scanline sync) limits the game a second time: the log and the settings menu say so, and setting it to 0 in RTSS
# leaves one limiter.
# 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.

# 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

# Water surfaces and the springy floors (the Deku Tree's webs) are simulated in fixed steps of 1/60 s, as many as the

# 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

# 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

# The step the game is given each frame: 1 keeps it steady (the same value from frame to frame while the frame rate

# 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.

# framegen = off
# On Linux dlss runs through NVIDIA's NGX itself, without Streamline: it needs dlaa = 1 with DLSS when the game starts

# once, and its multiplier is fg_mult: 2 to 6 (above 2 needs an RTX 50 GPU) or dynamic, which generates only the frames

# 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
# With framegen = dlss, Reflex holds fps_limit where each frame starts, before the controller is read, and the game's
# own limiter keeps only its ceiling of 240 frames a second: a finished picture no longer waits for its turn, which
# takes up to a frame of the game's off the delay from the controller to the screen. The game's own limiter takes the
# limit back while a movie plays, while the window is minimised, and for the rest of the run when the frames show that
# Reflex does not hold it; the log's "frame rate:" lines say which one holds it. 0 leaves the limit to the game's own
# limiter, as before 0.10.2. Needs the nx2navi_dlssg.dll of 0.10.2 or later (an older one leaves the limit to the
# game). Changes while the game runs take effect at once.
# reflex_limit = 1
# 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

# 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

# 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

# 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

# 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
# With wb_lazy: 1 (default): when the game's CPU code touches memory the video card wrote, the copy that brings it
# back holds up only the threads that touch that memory; the game's other threads, the video card's bookkeeping and
# file reads go on meanwhile, and several such copies can run at once. 0: every such copy holds them all up until it
# is done and the copies run one at a time, also those made when video memory runs short, as in 0.10.1; only a thread
# that touches memory while it is being copied still waits for that copy alone. Set 0 if the game ends or the graphics
# device is lost where it did not before, and send the log.
# wb_lazy_unlocked = 1
# 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

# 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
# on such a card, and on the RX 6000 series with AMD's Windows driver, where the game drawn with mesh shaders lost the
# graphics card in play ("driver timeout", the game ends with code 72); there it costs some frame rate, and a place's
# ground, rocks and plants show a moment late the first time they are drawn in a run. 1 does it on every card (for
# testing: it is slower than mesh shaders); 0 never: an RX 6000 card then draws with mesh shaders as version 0.10.1
# did, and a card without them 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

# 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).
