I recently updated my drivers to 17.7.2, it looked fine at first.
The only thing suspicious was a message that Watt-Man had been reset to default settings... well okay.
But it seems like the driver is not working at all. All games that used to run perfectly have a very low framerate now, hell even Fallout New Vegas is choppy. It looks like its using the default Windows drivers.
Also ReLive recording won't work.
Windows 10 ( Newest version I suppose )
16GB DDR3 Ram
AMD R9 390
Intel I7 4790K
Edit: I already uninstalled and reinstalled the drivers. Still the same result.
Edit 2: Somehow restarting my computer solved it now. Werid O_O
