So, since my last Crimson driver update (Driver Packaging Version 15.30.1025.1001-151204a-296874C) the performance of my R7 M260 decreased harshly. I'm running Windows 10 x64 on a i7-4510, got 8GB RAM.
Since this last update I have serious lag whenever something new "appears" on the screen.
Like the first render of everything lags a lot for a few seconds, but after that things get back to the usual. I never had these problems and I even tried to change some settings on the Crimson Control Panel (specially Shader Cache which sounded like would help me) to no avail.
When playing DotA2, for instance, I gotta scroll my screen through the map before the start of the game so I can play at the usual 60 fps.
So, any tips on how to solve that?
