http://global.phoronix-test-suite.com/?k=profile&u=phoronix-31974-10432-20657 Added in at the right end are the results for EXA and UXA (with no extra options being set) when building the xf86-video-intel 2.7.0 driver with the Linux 2.6.30-rc2 kernel. There's a few areas where the performance has improved, but there is certainly some slowdowns still.
