1 month ago Hello @ilievi187, the Steam client is not responsible for power or clock management of video cards. This is something for your video driver vendor to look closer at in detail.
Closing as not a Steam issue.

Subject: AMD 7900 XT Driver Issues on Linux
Hello,
I’m not sure if this is the correct place to report this issue, but I’ll post it here and hope it can be forwarded to the appropriate team. Feel free to delete the thread once it’s moved.
At the moment, the driver for the AMD 7900 XT isn’t functioning correctly. It seems to have the wrong power table, or something else is off. I’ve tested all the supported Linux distributions, and the issue is the same across the board – my 7900 XT is locked to 265 watts and boosts to a maximum of 2 GHz. In gaming scenarios, it doesn’t go beyond 200 watts, and I’ve verified that I’m not CPU-limited in the games I’ve played.
On Windows, everything works as expected without intervention. The card reaches up to 330 watts, frequencies are stable, and the FPS is 2-3 times better with no stuttering. This leads me to believe that the problem lies with the AMD Linux driver.
I’ve tested various Linux distributions, including Arch, Debian, Sid, and others listed as supported on the site. I’ve tried both old and new kernels, and the result is the same every time. It doesn’t seem to be a distro-specific issue but rather a driver-related one.
Another problem is that the zero-RPM mode is hardware-locked, so I can’t disable it. This causes the GPU to run hot, whereas if I could set the fans to just 10%, the temperatures would be fine.
Since I bought the 7900 XT, I’ve been unable to use Linux effectively. Please, this issue has persisted for two years now, and it needs to be addressed. I’ve been a Linux user for years, but this has made the platform unusable for me with this GPU.
Thank you for your attention to this matter.
