I think the performance regression of intel driver is due to the lost of
the 'INTEL_BATCH' variable.
This variable can be set in Hardy to get a huge performance boost in 3D (can be
seen in glxgears, but also openarena, compizeffects...)
for example in Hardy, compare the output of :
glxgears
and

Public bug reported:
Binary package hint: xserver-xorg-video-intel
The INTEL_BATCH=1 environment variable doesn't seem to work in Intrepid.
This option is used by many users to improve 3D performance in compiz, games,
etc... on intel chipsets (i915, i945...)
For example, without this option, i
With Hardy alpha5 :
On my laptop (i915GM) it seems that MigrationHeuristic="greedy" is not enabled
by default.
i changed xorg.conf to put the lines
Option "MigrationHeuristic" "greedy"
Option "ExaNoComposite" "false"
and the results (glxgears fps) were the same as before : no performance

I tried the INTEL_BATCH=1 on my laptop (i915GM, pentium-M 1000MHz ULV) and it

I have the same measures with EXA or XAA for acceleration.
glxgears :
+33% (655fps->871fps)
openarena benchmark :
+32% in 640x480 (22.8fps->30.2fps)
+18% in 1024x768 (14.9fps->17.6fps)

I saw a terrible fps drop between feisty and gutsy, it was due to a irq
conflict (see bug n°155985)
I solved this by booting with options pnpbios=off irqpoll
maybe it could help ?

Solved !
I changed the boot options to : pnpbios=off irqpoll

Looks like it was a hardware problem, not related to the

keep up the good work !

The performance regression is seen without enabling compiz.
All the files i sent (xorg.conf Xorg.0.log lspci and now glxinfo) come from a
