AMD Crimson doesn't recommend game setups? Is this Raptrs gaming evolved? Whats your CPU like, is it working well? Skyrim will lag as the CPU isn't enough for the draw distance, even my 8350 @ 4.75ghz just cuts it now. Minecraft with lots of AI, yet simple AI would suggest the same. Check your CPU clock and usage while in game.
Overclock seems to be the best bet, you should be getting with better performance anyway, but might be the boost you need.
Whats the current speed of the CPU, RAM, NB, HT. And that's your GPU like, clock and ram?
what is the gpu clock speed in game ?
