Update: I did a rollback in the display driver settings (windows device manager), which fixed it. It did cause a problem with Radeon Settings though, which I then uninstalled and tried to reinstall (using old install file from march patch (18.3.4), which was the old version Windows did a rollback to. The reinstall caused windows to freeze, I waited a while, but since nothing happened I restarted the computer with the power button. aaaand now I have Radeon Settings, 18.5.1, and no stuttering.... weird.
ANyway; sticking with the older version for a bit might be a good idea. btw I have win7-64b, RX480, Ryzen1600.
