Does anyone else have an issue with applying msaa and sgssaa? I've been experimenting between the smaa included in Durantes work and nvidia inspector applied msaa +sgssaa. What will happen, is I'll leave smaa off, and apply the inspector AA, at say 8x each and my framerate will tank. So I'll experiment until I get a good fps and image quality balance. But if I turn them off, and flick over to smaa, it doesn't seem to turn on. Then I'll turn smaa off, try the msaa +sgssaa option instead and it wont go on either.
It seems that, as soon as I apply smaa after turning off msaa +sgssaa from inespctor, anti aliasing just stops working for both. Gah, trying to get a balance between it looking smooth and the game running smooth is driving me up the wall!
