The Nvidia bros were talking about the harmful effects of ultra shadows and anti alias earlier. It applies just as well to us ATI friends.

You can either have high resolution, non-pixelated iShadowMapResolution=4096 shadows, or you can have 2046 blocky shadows with 8x antialiasing. Not both maxed at the same time, unless you want 15 FPS. Focus on one side of the spectrum and you'll be pleased.

With iShadowMapResolution=4096 I got around 30 fps with 4x antialiasing and a cool 55fps with 2x antialiasing. One must force the AA in the Catalyst Control Panel and disable morphological filtering, I've found. I don't know what morphological filtering is, but with 4096 shadows, it's a 10 fps hit. 2x EQ AA looks even better, whatever the 'EQ' means. Or just make it easy on yourself and use FXAA and move on with your life.

No matter what setting, the disco-ball shadows are always on my character's body. Setting fShadowBiasScale to around 1 seemed to stop these ugly shadows being cast on my female nord's pretty face and only cast around the shoulders/neck/torse, which are still pretty but not as important.

and my results are with a 6950 and phenom 955
