Hey guys,

I am having quite low FPS on very old games with M2 Pro (actually quite good CPU and GPU).

I tried Half-Life 1, it has 100+ FPS in some areas but depending where I look it drops to 20-30 FPS and is very stuttery.

Tried the same game with Parallels Windows 11 and it runs 200 FPS with no drops.

Tried another old game (Shogo: Mobile Armor Division) from the same era, also 15 FPS, very stuttery.

Both games are rated perfect (5 Star) in the compatibility list here...

Any ideas on this?

As far as I know the renderers are

Half-Life 1 uses OpenGL
Shogo uses DirectX 6

Apple doesn’t provide a native OpenGL implementation on Apple Silicon systems, what’s Apple does provide a OpenGL over Metal mainly for WebGL that’s why Apple required the use of the Metal API when submitting to the AppStore.

The best you could do it run the game using software rendering.
