Problems with eGPU (7700xt) on Bazzite
Hello everyone, this is my first post here and i really love bazzite, but im not used to Linux, so please be gentle 🙂
Here is my hardware:
Device: Lenovo Legion Go
eGPU: Radeon RX 7700xt
eGPU Adapter: ADT-Link UT3G
Script: All Ways eGPU for Linux
Here is my problem:
Setup was pretty easy and everything works out of the box for the most part. In most games, i have a strange behavior with frames: The frame rate is much higher compared with the iGPU, but every like 5 seconds, my frames need significantly longer to render. Frame times then are spiking as crazy, making everything impossible to play. After one second, everything is back to normal, then repeats. Funny thing is: Windows does not do that, frame times are crispy clean there, so it has to do with bazzite i guess.
Things i have already tried:
- Another TB 4 Cable from cable matters
- disabling cpu boost
- different CPU scheduler
- setting TB Mode on UT3G to pcie+pd
- applying AMD fixes mentioned on the All ways egpu github Page
Is there anything i can try, because for most people, egpu seems to work flawlessly. Help is much appreciated!
Thank you very much guys
