I am having artifacts also on full screen mode. To check my 2d and 3d clocks, I noticed I have no performance/overdrive tab in ccc. I tried rivatuner but again, there was no tab to adjust clock speeds. There shouldnt be any overclocking going on though.
I think by disabling the slave adapter in hardware manager, I disabled those features? But if i enable it I get bleuscreen on windows boot.
Any suggestions? Thanks
