This is with nexuiz, demo1, high quality, hdr off, 2560x1600:
1910 frames 81.2050000 seconds 23.5207192 fps
Lowering the resolution to 1920x1200 I still get only 30 fps instead of 23.
Recently Michael at Phoronix got 150+ fps in nexuiz @1920x1200 with a slower card (HD6870), slower and with a least mature support!
Cpu is a 2,7GHz dual core. OS gentoo amd64, kernel is linux-3.0.0-rc3, today's mesa/libdrm/xf86-video-ati snapshots, xorg-server 1.10.3.
It isn't even faster than my previous HD3870 :(
Openarena is even worst... Yesterday I get 30 fps at the first run, 90 at the second and 160 at the third, today I get a costant ~30 fps :(
~ $ openarena +exec anholt 2>&1 | egrep -e '[0-9]+ frames'
840 frames 26.9 seconds 31.3 fps 3.0/32.0/237.0/14.3 ms
I use the high power profile, I disabled swapbufferwaits, this is my /etc/drirc, pageflipping and color tiling on... I attached my xorg.log :(
