Not utilizing my GPU fully in Linux.

[Ic0n]

As the title suggests, the game is not fully utilizing my GPU.

During practice matches, the GPU's Core Clock only reaches around 1200MHz, occasionally hitting 1500MHz. I've tested this with Nvidia drivers 555 and 560, as well as various Proton versions, including Proton Experimental, Proton CachyOS, and Proton-GE-Custom. I've also experimented with both X11 and Wayland. On Wayland, I noticed an increase in mouse latency.

In other games, the GPU Core Clock easily reaches ~1800MHz without any issues stable.

Here are the details of my setup:
- OS: CachyOS with kernel 6.10
- CPU: AMD Ryzen 5800X
- GPU: Nvidia RTX 2080 (Core Clock ~1800MHz) with Nvidia drivers 560.

Do you have a frame rate cap and are you reaching it? It’s not always a problem that the GPU isn’t being used fully. If I play in 1080p60 the game will use 20% and if I play in 4k 120hz it uses 100%. So if the graphic settings aren’t demanding enough it may not use 100%.

Another thing is that if you have a CPU bottleneck the GPU won’t ever hit 100% either.

Thanks,

Playing at 1080p
I do not have any framecap on. Trying to get as much fps as possible. I am around 150-200fps in the practice map. When i have the Framrate cap at ~240fps.
The GPU is pushed to 90-99% and CPU is around 30-40%

I thought I was the only one who noticed this regression. I used to get 230fps at training circuit looking at the wall (yes, checking what's the max fps I could get) but yesterday I did the same test and unfortunately was getting around 150-180fps. Where are my 230fps? :(

Do you have the possibility checking your core clock on the GPU?

Seems like it’s working fine to me. It’s rare to have a perfect combo with CPU and GPU. So typically any system is going to have a small bottleneck, either on the GPU or CPU. They don’t consider it a bottleneck until it’s 10% or more which falls in line with your GPU usage. Which is higher than 90% so that means the bottleneck is less than 10%

If you can enable GPU and CPU frame time you’ll be able to see which component is holding you back. The component with a higher frame time is the bottleneck. Like I said though if it’s less than 10% it’s a diminishing return to try and fix that.

Another thing is that just because the CPU isn’t at 100% doesn’t necessarily mean it isn’t bottlenecking the system. Lets say you have 6 cores and they are tasked, the task may only use 40% of the core but only 1 task can run on a core at any time. Ignoring hyperthreading that is. So speed and hyper threading matters a lot too. Most games won’t use more than 6 cores 12 threads so higher core counts are usually less important for gaming. Speed and hyper threading is king for gaming.

In conclusion it appears the system is working as expected and there isn’t an issue other than a loss of 10 FPS approximately.

It seems that The Finals currently lack NVIDIA support for Linux. However, I found a workaround by adding this to the launch options:

`PROTON_ENABLE_NVAPI=1`

Unfortunately, the issue resurfaces whenever I Alt-Tab out of the game.
