- overlay.fps: SDL software renderer → GPU texture quad, top-right corner,
yellow EMA-smoothed FPS counter; LOADOP_LOAD preserves scene beneath it
- debug.screenshot: one-shot step that writes status txt + BMP then pushes
SDL_EVENT_QUIT for automated visual feedback loop
- Adaptive vsync: graphics.gpu.init "auto" present_mode queries actual monitor
refresh rate via SDL_GetCurrentDisplayMode; ≥120 Hz → VSYNC, <120 Hz → MAILBOX
Fixes vsync cap on 165/170 Hz monitors reporting as 240 Hz in settings
- Fixed present_mode wiring: q3_game.json gpu_init_viewport node now passes
present_mode as a direct parameter (workflow variables are not seeded into
context by the executor, so the variable section was dead data)
- Stair climbing: probeReach 0.45→0.70 for earlier detection, jam detection
nudges player up after 100 ms of horizontal blockage, step_height tuned to 0.6
- Physics dt: real wall-clock delta clamped to [1/600, 1/30] so 240 Hz displays
don't run physics 4× faster than intended
- GUI smart search paths: _candidate_build_dirs() scans all generator dirs ×
build types × flat and Conan-nested layouts, sorted by CMakeCache.txt mtime;
_find_binary() picks freshest sdl3_app.exe; packages loaded relative to
__file__ so gui works from any working directory
