On a similar setup (RV350 in a PowerBook) here, it runs at about 60-70 fps with compiz and just above 100 fps without compositing. BTW, are your UMS numbers from driver version 6.13? With EXA or XAA? > This makes most 2D games unplayable. I'm not sure the test app is really representative for 'most 2D games'. -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
