chaosapiant: How hot are you video cards getting? Higher temperatures can cause artifacts. And if this is the case, it's the reason that getting a new card didn't help.
Well I skipped through to this scene and I didn't test anything else and it happens every single time.
Driver settings were completely untouched btw, nothing changed. Newest drivers installed.
Can anyone else with an Nvidia card confirm that I'm the only one with this specific problem?
EDIT: Also, forgot to mention. This is running on a clean system install. Entire system was formatted and reinstalled.
