Pandemonium,

I was addressing citizenofnowhere, and his issue is almost certainly due
to vblank_mode being enabled - but he is using new version of the intel
and libdrm code. I don't have access to any Intel hardware in order to
test at the moment, so I can't comment any further. If you see a
glxgears result that's constrained to your refresh rate (e.g., 60-62fps
for a laptop, or a rate corresponding to your display device such as 70,
75, 85), then the problem is vblank_mode (and perhaps the environment
variable is broken/ignored in the new driver, so it cannot be
overridden). I can't say if the problem applies to you.

>From my understanding of events, we're kind of in a transitional stage
with regards to DRI. We had the introduction of DRI2 which was initially
supposed to be in the form of TTM, which then got dropped in favour of
GEM, and I've been reading some complaints that GEM is too Intel-
centric, thus unsuitable for other chipsets. I have no idea what the
situation is at the moment, but I honestly don't think the Xorg
developers are concerned so much with performance for the legacy DRI
code at this time, which is unfortunate for users (but also
understandable).

Bryce knows a lot more, and he's already explained the situation (re:
performance of the 2.4 vs 2.5 driver and absence of the legacy
INTEL_BATCH variable).
