Nvidia announced that this is a hardware limitation. They cheaped out on the memory controller which is causing the problem. You basically have a 3.5 game card.
All games using 4GB in the future will have frame pacing issues, on top of lowered performance, but if you plan on keeping your card for over a year it has no future proofing. Nvidia press statement is reporting an average performance delta to hide the problem. Don't be fooled by this as the instant performance hit leading to lower than average results actually results in sporadic frame times, screen tearing, and judger for gamers when it happens. For games that will use 4GB in the future this card will be SOL.
