Running a pi 4, latest raspberry pi os/raspbian, latest steam link version, everything connected through ethernet. Whenever I try to use my steam controller I get a constant 9-10% frame loss showing in the details overlay and it makes for some pretty jittery gameplay. I've tried both using the dongle and plugged in directly with a usb cable. As soon as I turn off/unplug the steam controller frame loss immediately drops to 0%. Using kb/m or dualshock 4 controller also results in 0% frame loss which leads me to believe it has to be something with the drivers for the steam controller...
I've spent the past couple of days googling everything I could think of and haven't been able to come up with a solution... has anyone else ran into this issue or heard of it?
