Are you aware of the performance issue on AMD systems running 20.04? I see that "1fps when laptop screen disabled" bug got some attention and there is a work going on it. I don't know if the problem I am facing is related to it or no. If you want I can provide more data
Got the same 1fps thing here with Nvidia hardware. I can only assume that the OS tries to save power and trottles the GPU or the USB controllers. I tried to prevent this but no success. Any ideas here?
