@Sam-site Thanks, that's exactly what was needed. It's basically the command for hardware cursor I think, which is perfect until nVidia fixes their stuff.
It seems to be a problem with the game not using hardware cursor. I had the exact same issue in Sins of a Solar Empire: Rebellion, and the only way I could fix it was turning on the Use Hardware Cursor option.
BlackOPS is divided into 3 mods. Did you get all of them?
Swarm Eternal is brutal indeed, but my problem with Uveso and Swarm is that you are basically playing a survival game most of the time, they just spam T1 continously.
