Regeneration

The solution is to use ATi card instead. Nvidia is not using many beta testers (like ATi for e.g.) before they introduce a new driver to the public. Every time they fix an old bug, they are introducing new ones. It will keep happening, until they will start using some kind of beta testing campaign. OR appoint someone really good to the software dept. director. Until then, use the 84.xx or 81.xx series instead.
