Subject: [PATCH] [util] Spoof Nvidia cards for Crysis 3

The game for some reason runs significantly slower in CPU-bound scenarios
when it recognizes an AMD GPU. On the other hand, there seems to be a small
performance hit on an actual Nvidia GPU (GTX 670) in GPU-bound scenarios when
doing this, but on most setups the tradeoff should be worth it.
