I've confirmed the large difference between 173.14.12 and 177.80 drivers using the the OpenArena benchmark (both on amd64 installations with compiz running):
Intrepid, 177.80:
840 frames 3.1 seconds 267.9 fps 1.0/3.7/20.0/2.0 ms
840 frames 3.3 seconds 254.5 fps 2.0/3.9/33.0/1.9 ms
840 frames 3.4 seconds 246.8 fps 1.0/4.1/223.0/7.9 ms
average 257 fps
Intrepid, 173.14.12:
840 frames 1.8 seconds 471.1 fps 1.0/2.1/11.0/1.0 ms
840 frames 1.9 seconds 435.7 fps 1.0/2.3/11.0/1.1 ms
840 frames 1.8 seconds 465.4 fps 1.0/2.1/11.0/1.1 ms
average 457 fps
Hardy, 173.14.12:
840 frames 2.0 seconds 428.8 fps 1.0/2.3/19.0/1.0 ms
840 frames 1.9 seconds 434.3 fps 1.0/2.3/11.0/0.9 ms
840 frames 1.9 seconds 444.2 fps 1.0/2.3/10.0/0.8 ms
average 435
Using the averages, Intrepid's 173.14.12 driver comes out faster by 5% than Hardy.
But Intrepid's 177.80 driver is a whopping 44% slower than its 173.14.12 driver, so there is clearly a big performance difference between the two.
I seem the same degradation playing games under wine with 177.80 - once many things start going on concurrently, the fps reduces enormously and they become unplayable.
