I understand that most of the games you play in Linux are using some sort of "emulation" and that might h= ave some affect here (which is then issue that you need to take with the folks = who develop that part if it turns out to be the problem). I did some testing back then with Unigine Heaven:=20 https://benchmark.unigine.com/heaven=20 Can you perhaps run that (or anything similar) and see what's the difference between the two OSSes on that same hardware? Then we would need to understand the hardware configuration, can you add the full dmesg and output of 'sudo lspci -vv' when you have the eGPU plugged in? The third thing that comes to mind is that do you have any PCIe ASPM states enabled? That can be seen in the dmesg too I think and also in the lspci du= mp. Also do you have the monitor connected directly to the eGPU outputs or the host? --=20 You may reply to this email to add a comment.
