The Linux build uses OpenGL so its slow. The windows version through proton will use Vulkan which is much faster.
Comment on [Help] Euro Truck Simulator 2 is not running full speed on Steam Deck.
SSUPII@sopuli.xyz 9 months agoUnder Proton 8.0 presets (DirectX11 renderer):
- Ultra -> ~50FPS average, 100% GPU usage, 40% CPU, 70°C
- High -> ~60FPS average, 90% GPU usage, 30% CPU, 55°C (When uncapped ~70FPS average)
- Medium -> ~60FPS average, 50% GPU usage, 25% CPU, 55°C (When uncapped ~120FPS average)
- Low -> ~60FPS average, 20% GPU usage, 20% CPU, 40°C (When uncapped ~160FPS average)
Yeah, looks like the official Linux build of the game is not as optimized as I tought.

The fact that it’s OpenGL matters little. It is a misconception that Vulkan is faster. But in this case, their implementation does seem slower.

Isn’t it true specifically on Windows, because the Windows implementation of OpenGL is lacking, but false on Linux?

Windows integrates only very early versions of OpenGL. Any modern release is implemented by the driver of your 3D accellerator/video card.
OpenGL on Windows has always been kinda of a disaster, DirectX support being more developed is night and day.

Unfortunately, it’s pretty common for the linux version to have optimization issues and perform worse than the windows version through proton.
It does really highlight what a great job the various proton/wine/dxvk/etc projects have done with running windows games efficiently though.

It struck me as odd actually, as I have always believed this to be a beautifully optimized game (it still use). I’ve used the Linux build on my laptop (with propritary NVIDIA) and runs exactly like the Windows version.
On Steam Deck under Proton I am now using the High preset, then manually maxed out environment quality, weather quality and population and still remains at fixed 60.

Proton DB agrees, use proton experimental
