-"I haven't tried to fix the shimmering trees yet. They were there when I was using 6x AA so lots of AA doesn't seem to help. Maybe turning down the mipmap detail level in the driver will.-"Have you tried setting theATi Direct3D settings for AF from Performance/Quality: Performanceto Quality or Application Preference ?Kurt M

Yes, I originally had everything set to Quality or High Quality (whatever was the highest) with 6x AA and 16x AF. Everything set to override the application. That's when I first discovered the shimmering. So there wasn't anymore to give it.
