It seems that NVIDIA moments ago released a new Beta of their 180.84 GeForce drivers. This is tagged with Beta 3 opposed to the previous Beta 2. It also seems that a lot of stuff for GTA 4 users was fixed. If you play the game, definitely check out this batch.
There's a discussion thread open on these drivers right here.
