I can hardly spot any difference between 2.6.0-test2, A3 and A3-O12.2
while running the test as outlined in:

http://marc.theaimsgroup.com/?l=linux-kernel&m=105956126017752&w=2

I'll never do such a three hours again... All was equally well, which
probably just means that my environment is too lightweight during
"normal" operation. So I had to focus on the taxing game scenario.

XFree86 Version 4.3.99.9 compiled against my glibc 2.2.4, and the same
story with winex 3.1 running "Baldurs Gate I":

_2.6.0-test2_

Animations have cyclic hacking like --- . --- . --- . (dots are pauses).
Ambient sound hacks in concert, with an almost oscillating quality.
Mouse pointer is impossible to place since movement can mean a few
pixels or a full screen. Panning the play area is, of course, a real
pain. Playability = 0 (on a scale from 0 to 10)

_2.6.0-test2-A3_

All problems gone. Just slight bumps (very short graphic pauses) when
doing a long play area panning. Sound is not perceptibly disturbed by
any graphic bumps. Playability = 9.

_2.6.0-test2-A3-O12.2_

Regression compared to plain A3, both in sound and animations. Mouse and
panning seem less regressed. For example, a character can take four
steps, freeze for half a second, take another four steps, freeze etc.
Playablility = 8.

I did the game-test two times with each A3 and A3-O12.2 (alternating
boots) and the results were persistent. Looking at a "top" terminal
while in the game, I couldn't spot any striking differences between the
numbers. Just one oddity - and now I'm uncertain of its validity - as
can be seen on the screencaps below. In A3 wine had a PRI of 25,
wineserver had 15. In A3-O12.2 the numbers were reversed. I can redo the
test if necessary.

( the niced process is foldingathome, always running on my system)
