I am experiencing bad mouse lag with my Wifes Dell Optiplex 990 MT with an RX570... I realized it is related to the video card driver when I was chasing down the HDMI audio device not installed issue, while the AMD adrenaline 2020, I am currently using 20.11.2 The newest version has the HDMI audio issue it also still had the mouse lag too... I'd like to find a fix before I give her back her computer...The lag goes away when I don't use the AMD drivers. Any help is greatly appreciated.
Still have the issue, been trying to fix it, I tried ALL the recommended "fixes" I could find on Google, Still nothing, and the issue goes away when I uninstall Adrenaline 2020.
