The original game crashes on modern multi-core CPUs.
Method A (Revival patch does this automatically):
Open configs/unnamedsoldier.cfg (or mohaa_config.cfg) and add:
seta r_multithreaded 0
seta cl_maxpackets 60
Method B (manual fix if still crashing):
Launch the game, open console (~) and type:
com_affinity 1
Then restart the game.
Alternative (process affinity):
Start game → Ctrl+Alt+Del → Task Manager → Details → right-click MOHAA.exe → Set affinity → CPU 0 only (uncheck others).
(Repeat each launch unless you use a launcher script.)

Getting Medal of Honor: Allied Assault (MOHAA) running on Windows 10/11 requires addressing a few dated engine quirks, specifically related to OpenGL, resolution, and old DRM protection. 1. Fix Launch Crashes (OpenGL Error) medal of honor allied assault windows 10 fix upd
If the game crashes on startup with an "OpenGL Subsystem" error, it is likely because modern drivers don't always communicate well with the old Quake III engine.
The DLL Fix: Locate an opengl32.dll file (often found in community patches or by using a wrapper like Mesa3D) and place it directly into the game's root directory next to MOHAA.exe.
Compatibility Mode: Right-click MOHAA.exe → Properties → Compatibility. Check "Run this program in compatibility mode for" and select Windows XP (Service Pack 3). Also, check "Run this program as an administrator". 2. Enable Widescreen & 1080p/4K Medal of Honor: Allied Assault - PCGamingWiki PCGW
120+ FPS. Capped at 85 FPS by default; See Increasing frame rate limit to change the default cap. High dynamic range display (HDR) PCGamingWiki
If you are trying to launch the game via the default launcher menu (the screen where you select "Play," "Options," etc.), it will likely crash.
The Fix: Bypass the launcher entirely.
| Component | Setting | |----------------|--------------------------------------------------| | Game version | GOG or OpenMoHAA | | Renderer | OpenGL (via OpenMoHAA) or Vulkan (dgVoodoo2) | | Resolution | 1920×1080 @ 120Hz (capped via driver or in-game)| | Sound | OpenAL soft – 44.1kHz, 16-bit | | CPU affinity | Set to single core if using original exe |
The game might require patches to run smoothly on modern systems. Look for official patches or community-made fixes.
Since links can sometimes be tricky, the best repository is usually PCGamingWiki. Search for "Medal of Honor Allied Assault PCGamingWiki" and look at the "Fixes" section. They host the widescreen fix and explain the config edits clearly.
