since I've updated the driver to 17.4.1 and also tested 17.4.2 the drivers aren't working on my computer. If I start a game or nearly everything which needs a 3D-Session it cannot be started.
I completely reinstalled the whole drivers, deleted and cleaned up everything, not working. The desktop operations are not affected and multiple displays are working. Only the 3D part makes problems.
After installing the new drivers and rebooting the fan of the card was furthermore fully running until 20 seconds after the login. I only know this problem from the beginning of the RX400-series where the drivers were a bit buggy, but after a few versions this problem doesn't appear again – until now.
After reinstalling 17.2.1 everything works again, so I'm currently running the old driver 'cause it works.
