There's no such thing as a 90% performance drop, glxgears is not a benchmark. As for vsync, it means that your framerate is tied to your refreshrate. This is done by default now to avoid heavy tearing issues when using 3D on intel chips. To restore to the old behaviour, put this in your ~/.drirc:
<driconf> <device screen="0" driver="i915"> <application name="Default"> <option name="vblank_mode" value="0" /> </application> </device> </driconf>
Replace i915 with the driver that suits your intel chip.
I would advise against using xf86-video-intel-2.5.x and libdrm-2.4.x until GEM is merged into the kernel and things start using it. We're sticking to xf86-video-intel-2.4.x and libdrm-2.3.1 now because the newer versions cause regressions. The main improvements in the 2.5 series are related to GEM, and as long as our kernel doesn't have that, there's no need for a newer driver than 2.4.x.
That works wonders! Thank you so much and I'm sorry for all the trouble I caused! I am surprised I did not find that anywhere through Google. As I am sure this is going to be any issue for other users should this information be put into a wiki entry? Then there could be a post-install message for xf86-video-intel which directs users to that wiki page? Also do you mind if I put that information on the gentoo bug tracker? Sorry Again!
