Low FPS in Gothic 2 with DX11 on MacBook Pro M1 Max - Any Advice?

Hello everyone,

I recently purchased Parallels Desktop in order to play Gothic 2 (with the DX11 patch) on my MacBook Pro M1 Max (64GB RAM). However, I'm experiencing very low FPS while playing the game. The FPS maxes out at 60 when I'm outside of the city, but it drops to around 25-30 FPS when I'm inside the city.

Considering that this is an older game, I'm surprised by the low performance, especially since most modern laptops and PCs can run it at 120+ FPS without issues.

Does anyone know how I can debug or figure out why the FPS is so low? Could it be a memory issue, or maybe the processor or GPU isn't being fully utilized by Parallels? Any suggestions or advice would be greatly appreciated!

Thanks in advance!
Feel free to adjust any details as needed!
