Performance Hit with Transparency Antialiasing
It turned out that TSAA didn’t affect the performance of card as negatively as ordinary FSAA modes. Take a look at the diagram:
As you can see, enabled Transparency Multisampling does not practically affect the performance even in the basic 8xS mode. This TSAA variety doesn’t however improve the image quality as much as Transparency Supersampling does, but even in the latter case the performance hit is less than 5%. So, if you prefer to play games with enabled full-screen antialiasing, you can turn Transparency Antialiasing on without worrying that you lose anything in speed.
