All right, let me tell you what I know so far.

1. Enabling Vsync and Triple Buffering may help, but my AMD VISION menu doesn't allow me to do that.
2. This game played PERFECTLY on this laptop before, but suddenly started becoming choppy.
3. My video card isn't bad, other games work fine (With the exception of TF2 which gets the same framerate)
4. I don't have a virus.
5. My specs are: Processor: AMD E2-1800 APU with Radeon HD graphics 1.70 GHz RAM: 4.00 GB OS: 64-bit Windows 8 Someone please help. I've been everywhere.
