I have problem with Windows 10 Pro 1909 KB4560960 update. This update makes my RX 480 8GB unstable, GPU crash or freeze. OS was little slow. Everything is fine after uninstalling this update.
AMD driver v20.4.2 / 20.5.1
It's weird because I updated again and now OS works better.
Solved! Go to Solution.
KB4560960 is almost 400 MB cumulative update.
Win 10 clean installation is 2 weeks old.
Everything is fine after uninstalling this update.
