[Problem]
Extreme Tux Racer shows a significant 66% performance regression compared with Hardy.

[Original Description]
I've been experiencing it since clean install of alpha2, but now I've booted from Hardy LiveDVD and done some benchmarking.

Extreme Tux Racer IS a benchmark, isn't it?

Game settings: all graphics extras are disable, except from FPS; 800x600 resolution.

Hardy: ~60 FPS
Karmik: ~20 FPS

3 times drop!

glxgears (definitely not a benchmark, but...)

Hardy: 4200 frames in 5 secs
Karmik: 1400 frames in 5 secs

3 times drop again. And compiz feels slower as well.
