I installed the 313.95 Beta drivers when they were released, and today I was playing Battlefield 3 on the map "Grand Bazaar" and this started showing up:

I played Battlefield 3 before this happened on several maps, and like 2 hours in a single Caspian Border map straight and this didn't occur.
I didn't have any performance drops or lag of any sort, all the textures just went wild and started changing colours on the scale of a rainbow.
Is it a BETA driver issue or is my GPU derping?
