Fix Proton map-load crash with Source stability flags

CO Copilot committed 2 Jul 2026 · c9301c7f32 · 2 files, +25 −0

The intermittent hl2_win64.exe crash during map load was Source SDK
2013's multithreaded render/anim paths + joystick init under Proton/DXVK
(crashed with the client JS runtime disabled too, so unrelated to JS).
Add openvibe_proton_stability.cfg (mat_queue_mode 0, threaded bone/leaf/
shadow/ropes off, snd_mute_losefocus 0, mat_dxlevel 90) exec'd before
connect, plus -nojoy -insecure -nohltv launch flags. Client now survives
past the load window and reaches the menu/map reliably.
