Answer

You could try reverting to the previous video card driver. If the issue was in the driver upgrade, maybe the old version will work better. If that doesn't solve the problem, it's possible it could relate to SP1. But I don't know what that could be. Another option would be to re-install SC2. This may allow the config files to adapt to whatever new changes are in your system.
