demm Uf.. Thank you!! That worked. I just didn't know where drivers are stored. So i know that nouveau is not for me. I returned to nvidia and it worked fine and smooth. However as You see below - OpenGL renders from llvmpipe instead of GeForce Gt630. This cause problem on Steam - I've succesfully installed CS:GO, but because of that it's unplayable - fps is about 5-10. Now the qeustion is - is there something i can do with that? I mean - is there a way to change llvmpipe into GeForce Gt630?
