Fallout: New Vegas

Notes

VERIFIED 10 Sep 2026 on this Mac: Apple M4 16GB, macOS 26.5.1 (25F80). Played from the Wyn tile: LaunchRecords 174s and 274s. Those records say layer=dxvk only because LaunchRecordStore.makeRecord copies profile.bottle.translationLayer — they are not a measurement of what rendered. The game ran Wine builtin d3d9 → wined3d → OpenGL on the frankea tree (users/ebenoelofse). 11 Sep 2026 lsof on the live FalloutNV.exe (wyn-handovers/FINDING-20260911-taskb-legs.md) loaded d3d9.dll, wined3d.dll and opengl32.dll from the frankea tree's i386-windows and rendered through AppleMetalOpenGLRenderer — DXVK was deployed and never opened. Wyn Libraries/DXVK/{x64,x32} ship only d3d11.dll and d3d10core.dll — no d3d9.dll on this machine; no DXVK log (DXVK always writes one on init). RendererInfo.txt (rewritten 11 Sep 16:48): NVIDIA GeForce 6800 / nvd3dum.dll, vs_2_0 / ps_2_a / BSSM_SV_2_A (Shader Model 2). That adapter is wined3d's D3D9 table entry, not DXVK — through MoltenVK it would report Apple M4. Army Men on the same wined3d layer via ddraw reported GeForce 8800 GTX; both are fake NVIDIA, different feature-level rows. FalloutPrefs.ini at the 274s exit: 1280x720 fullscreen, iPresentInterval=1, sD3DDevice="NVIDIA GeForce 6800". Gamebryo has no Unreal SessionPerformance log (iFileLogging=0). No new .fos this session (autosave.fos still 13 Aug; bAllowScriptedAutosave=0). Do NOT pin translationLayer to d3dmetal, dxmt, or dxvk — D3DMetal translates D3D11/12/10, this DXVK package has no d3d9, and pinning injects d3d9=n,b / d3d11 overrides that rewrite the bottle. Leave this profile's layer unset so Play does not merge those overrides (same class as army-men-rts). Steam launches FalloutNVLauncher.exe; prefer FalloutNV.exe with SteamAppId=22380. Keep iPresentInterval=1 — Gamebryo physics breaks at high FPS. This is New Vegas, not Fallout 4. Prefs live in Documents\My Games\FalloutNV. Do not use Libraries.rgl or Libraries.vk.
