Scroll down to "Multi-GPU Rendering Mode" and set it to "Single GPU"5. On "CUDA - GPUs", select "Use these GPUs" and select a GPU (*Note)6. Click the "Apply" button*Note: Preferrably the first GPU on your "main" card should be selected, but any working GPU should do.Also, if you didn't do step 4 and 5 in order, they'll likely revert themselves. So do them in order.On a side-note, I have two other issues. My game crashes after playing a few seconds, and sometimes when starting a game I can't use any weapons. Not sure if this is related.
