Low performance on Intel Arc GPUs on Arch Linux

[Crimson-Hawk]

I found that the performance of the GPU is significantly lower than Windows (measured with MangoHUD and MSI afterburner, respectively), especially with Cyberpunk 2077 even when taking into account the translation overhead. The discrete GPU is selected and the game is ran with the latest version of proton and operating system.

Steps to reproduce the issue:

1. Install Arch Linux 
2. Update with "sudo pacman -Syyuu"
3. Install KDE
4. Install Wayland
5. Install steam from multilib package list
6. Install MangoHUD
7. Install Cyberpunk 2077
8. Launch Cyberpunk 2077 with the latest proton version and MangoHUD enabled

As requested, this discussion is continued from here

Hello Crimson-Hawk,

Thank you for following our recommendation and opening individual threads for the issues you have encountered. We will be more than happy to assist you with this performance problem with your Intel Arc Graphics.

It is important to consider that Intel only develops graphics drivers for Ubuntu* 22.04; unfortunately, additional Linux distributions are not supported at this time. Since you confirmed that the performance issue is not present in Windows 11 (supported Operating System) and is only present when using Arch Linux, this may indicate that the problem is related to the Operating System. We recommend contacting the Linux distribution for further support.

Best regards

The kernel modules(drivers-windows term) supports the Linux kernel above version 5.9 that incudes Debian and arch Linux with version 6 kernels.
