If you’re using a GeForce card in your current PC, we suggest you head over to Nvidia’s driver page and grab the latest beta drivers for your card. Alongside a raft of performance updates (woo! 5.8 performance game in Batman. Batman is 5.8% happier) is the inclusion of MSAA support for Diablo III, Star Wars: The Old Republic, and more. As you can see from the graphs, they are better.
MSAA is good. You should get it.
