Euro Truck Simulator 2 is not running full speed on Steam Deck.

I am aiming at 60 FPS, but I am struggling to keep it at any settings.

I have performance UI brought up, and I have noticed this. Presets:

Ultra -> ~30FPS average, 90% GPU usage, 40% CPU, 65°C
High -> ~45FPS average, 80% GPU usage, 30% CPU, 60°C
Medium -> ~50FPS average, 40% GPU usage, 30% CPU, 50°C
Low -> ~50FPS average, 20% GPU usage, 20% CPU, 40°C

As you can see, I cannot reach 60 FPS in-game even at the lowest preset.

What can I check/do in this case? The Linux binary is being used.

Try Proton. Currently, Proton is much more developed than the Linux support for many game engines.
- Under 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.
  
  Proton DB agrees, use proton experimental
  
  The Linux build uses OpenGL so its slow. The windows version through proton will use Vulkan which is much faster.
  
  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's been a while but I think I also struggled to hit a solid 60 without substantial graphical downgrades. The biggest thing to check, if they haven't fixed it, is if you're using proton? The Linux version of the game, at least as of last year, is total crap. Running the Windows version through proton is a substantial improvement. Hopefully enough to get you to 60fps.
- Yeah, I am now.
  As replied in another comment, I switched to Proton 8.0 and can now reach fixed 60. Playing at high preset and manually maxed out environment quality, weather quality and population.
