Since I am on it I also ran the Rise of the Tomb Raider Benchmark using the native Linux version made by Feral Interactive against the Windows version using Proton Experimental. While the Windows version was ran using DX11 and DX12.

Preset: Very High
Resolution: 2560x1440
Anti-Aliasing: FXAA

Linux Native:

Mountaintop: 230.87 FPS (min 112.78, max: 410.66)
Syria: 182.56 FPS (min 66.97, max: 273.90)
Geothermal valley: 175.96 FPS (min 135.32, max 210.32)
Overall: 197.12 FPS

Conclusion: Similar to Shadow of the Tomb Raider Feral Interactive pulled of some serious performance benefits using the native Linux version compared to the Windows versions running via DXVK or VKD3D.
Also I find it noteworthy that while Rise of the Tomb Raider offers a DirectX 12 mode it seems to be in some early stage as it performed the worst here. Also the min fps are very concerning as they are very low. Which to me looks like some issues with the DirectX 12 renderer.
