I have Ubuntu 11.10 installed 64-bit. I have a Nvidia GTX 580(Zotac) and a normal AMD X4 Phenom Quad Core. I am using the normal Unity desktop manager(not 2D). When I start Ubuntu everything is fine. Moving windows works fluently but let say after some minutes of surfing I again try to move windows but now the windows just lag when moving. I have the proprietary drivers activated.

I had the same problem until 290.10.
You can get the latest Nvidia driver by adding the following PPA.
