I don't play computer games. Perhaps I'll render 3D videos or use Google Earth. I'll give it a try and remove the proprietary driver. Watching videos and editing videos must be possible for my needs too. I was pissed off when the old nouveau driver didn't work for my machine and some distros already dropped the nv driver. If 3D should work with the kernel-rt, I don't need the standard kernel anymore, resp. perhaps I'll keep a second kernel for emergency cases. Hopefully the nouveau driver won't cause real-time issues. I guess I'll run a jack midi latency test later or tomorrow.
In any case it's nice to see that a opensource alternative to the closed nividia driver is available and working better all the time!
Unfortunately we only can use it until 21 December 2012 ;D. Regards, Ralf
