I had Manjaro(Arch) previously and I had nouveau as my display driver and all the effects on cinnamon worked fine. In Sabayon they didn't work so I did the usual test. Run Xonotic on 1920x1080 with all the settings full. The game was unplayable. It had less that 2 fps compared to manjaro which I had Cinnamon and nouveau and I had 45fps there. What is wrong with my system?
I have: Nvidia GTX670, i53770, 8GBram.
I installed the 64bit Mate edition and changed the desktop environment to Cinnamon.
