Half-Life Forum

Hey all. It is awesome to be able to run the good old Half-Life on Crossover on MacBook Pro M1. The game is very fast in the beginning then it slow downs a lot in certain areas, during fights it can go down from 40fps to 10fps.

Am I missing something? 1080p, high def models. The bottle is configured with DXDK and high performance mode (there are two performance mode string in Italian in that menu, never understand what is the difference).

CrossOver uses an open source project called MoltenVK that translates the Vulkan rendering calls to Metal (the API macOS uses for 3D rendering). MoltenVK is still a work in progress (much like CrossOver/Wine itself). Most likely there are rendering features in this old engine that MoltenVK has difficulty with. Older games tend to use specialized 3D hardware features that modern games don't need anymore. Often these features are not available in Metal, so MoltenVK has to implement them in other ways usually via software and not getting the advantage of the speed hardware can provide.

That said, each new release of CrossOver will import a new version of MoltenVK. So test again when we ship CrossOver 21 (any day now).

Or, since you are a BetterTester, try our latest beta.

Hey Jeremy, I'm already testing Crossover 21 :) The game is playable and a jump into memories, having a lot of fun, but I was expecting it running a little fastest, I will keep testing next versions.

Indeed, it is quite unplayable in some level like the final boss fight with FPS drop to 5-10 from 60. You can't dodge attacks. Hope to see optimisations in the future, I will try a later date.
