A start that finds the pipeline cache written by another device or driver has nothing built, and everything was compiled beside the game: an 8-core integrated GPU drew fewer than 600 frames in its first 11 minutes. Such a start now waits on the "Preparing shaders" screen, with counts, for every recorded pipeline, for the compute pipelines on every core at normal priority, and, when a sample says the driver's own cache lacks the prepared stage libraries, for all of them on every core. The memory gate still holds for the builds, and the library builds write the preparation's journal while the start waits, so a variant the driver's compiler dies on is skipped from the next start on. boot-warm-owed.txt beside the caches names the GPU and driver: a start closed during the warm is followed by one that goes on with it, three at most, and "done" keeps later starts ordinary while the cache file still carries the earlier driver's header. When the boot stops waiting (prewarm_wait_ms, or a minute without progress) the builders step down to the background's thread counts and idle priority. prewarm_full = 0 turns the warm off. With nothing in the driver's cache the probe took 425 s on an RTX 5090 with 16 CPU threads: 87 s for 5,775 recorded pipelines, 19 s for 4,075 compute pipelines and 317 s for 42,231 prepared variants.

// The in-game menu (ui/menu.cpp, Dear ImGui) and its seams to the platform side: the window and its input (ui/menu_win.cpp
|
|
// on Windows, ui/menu_sdl.cpp with SDL), the gamepad (input_pad_read, input.h) and the present path
|
|
// (gfx_present.c). The menu core calls no window system: events come in through menu_event_*, the drawing happens in the
|
|
// present path's command buffer.
|
|
//
|
|
// F1 or Esc on the keyboard and Minus and Plus held together (consumed in poll_merged, input_menu_gate in input.h) open it;
|
|
// F1, Esc, B or "Continue" close it. While it is open the game gets no input (input_menu, input.h) and keeps running; the
|
|
// cursor is released from the mouse camera. Tabs Screen, Game, Mods, Sound, Controls and Menu (L / R or Q / E switch
|
|
// them) hold option rows (ui/option_rows.h) over the cfg settings and the mods folder (mods.h); the bottom row has
|
|
// "Continue" and "Quit game".
|
|
// Test hooks (ui/menu.cpp): NX2NAVI_MENU_TEST=<frame>[:<frames per page>] opens the menu at that presented frame and saves
|
|
// one swapchain shot per tab into NX2NAVI_MENU_TEST_DIR; NX2NAVI_MENU_TEST_SET=<frame>:<key>=<value>[,...][;...] sets settings
|
|
// at given frames without input (SAVE=1 writes nx2navi.ini, FOCUS=<key> puts the cursor on that setting's row).
|
|
//
|
|
// Threads: the event functions are called by the window thread, menu_toggle by whichever thread polls the pad, the
|
|
// overlay functions by the present path under its lock. ImGui itself runs on the present path only.
