Compiz is very laggy in ubuntu 11.04

[Nipas]

System: Ubuntu 11.04 amd64
GPU: nvidia gtx 460 (nvidia driver installed from "additional drivers)
All updates installed

Problem: Compiz does not run smoothly in my system as soon as other systems that I 've tested. For example when moving windows, open effect, minimize etc. This problem makes my system slow and with a sense of crap. All other main distros do not have such problems so I suppose compiz itself is not a problem. Furthermore, I want to add that Ubuntu 7.10 and 8.04 for example, did not have this problem (but I had older hardware)
Please emphasize on this problem as it is very important for users.
Keep up on good work guys!

Currently, I am not able to boot into my ubuntu system because of personal reasons. Also, I didn't reffered to a package because I can't figure out. It may be sth about Compiz but I am not sure. However, if any debbuging info is needed about my system ask it and I 'll see what can be done.
