   XNA 3.1 Antialiasing still not working
  I still can't get antialiasing to work in the Game1 class, even after using http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.graphics.presentationparameters.multisampletype%28v=XNAGameStudio.31%29.aspx.What do I do??   
  You should start by posting your code. Also make sure your AA settings aren't being overwritten by your GPU settings.   ;  Hi, thanks for replying!My code is an exact copy of the website I sent.Too bad I forgot about the GPU control panel. That was the issue. :\ I always set it to "application controlled", although this time it was forcing it to 2x. Thanks, I appreciate it.:)
