I'm having two problems with my card/drivers the first is that every time I restart my PC it ends up too small for the screen (with black borders around it ) even though my settings on the radeon software are correct, I temporally fix this by moving the hdmi scaling to 4% and back to 5%, this started a few updates ago, the last time it was fine was a 17.1 or something update.
The next problem is v sync is completely broken on nearly every game, I had to up on enhanced sync instead to make fps bearable since v sync was forcing nearly all my games into 30fps regardless of the game, how do i fix these issues?
