Like many others here, I've been dogged by the terrible mousing performance using Catalina and a RDNA card.
I just did a manual flip between my standard and backup BIOS to confirm that the latest updates with the newest AGESA has made a tremendous difference.
I'm using the F20a bios on my Gigabyte X570 Aorus Master currently.
I also saw some improvement moving from iMac1,1 to MacPro7,1, but this BIOS was WAY more impactful.
This actually feels like a high end Mac now. VERY responsive and crisp with mouse inputs.
