Yes yes i try it again and upgraded from kubuntu 12.10 mesa9.0 to oibaf mesa9.1-devel and the result is: its slower.
Yes maybe the mesa9.0 is only faster because 9.1 calculates more openGL effects but in the end its complete useless on my hardware.
is there any improvement planet for this kind of hardware generation? hd4000?
or is it just another way to say: fuck you customer buy new hardware you dump ass ?
