Using a Razer Deathadder V3 Pro with the optional Hyperpolling Dongle, setting my mouse to 4000 or 8000 Hz, I can create easily reproducible stutter when using the communications menu in game. This is noticeable in game and as more and more gaming mice on the market support polling rates above 1000Hz, I believe many more people may experience this problem.
I’ve uploaded a video to youtube to demonstrate the issue, which does not occur at 1000 or 2000Hz, but starts around 4000Hz and gets worse at 8000Hz.
