Doesn't that cause > stutter with other drivers? Hard for me to test fglrx on my setup, but soon I should have more ram to play with. The recent changes to to agd5f 3.19-wip seem to have provoked a new issue - haven't had time to find a commit yet. Will attach a screen showing that near the end of the demo there is a new really long pause (graph doesn't really show length, but it was around 10 sec) that corresponds to a big move from vram to gtt. Other demos eg. valley don't show any issues and run well. IIRC there is already a bug somewhere about the rendering issue (common to most unreal demos) that makes part of the logo black in the screen shot.
