poor performance under debian 7
I have just finished a debian 7 install. My video card is GeForce 7800 GTX and I installed the nvidia driver using dkms (driver version 304.88).
Running glxgears I get approximately 60FPS, previously my system was fedora 10 (dkms...) and I use to have approximately 13800FPS
What' wrong and what shall I do to enhance this?
