Finally nVidia added transparency anti-aliasing support for most (all?) GeForce cards. I tried the super-sampling AA on my 6800GT and it is really looking very very good. The MSAA has problems with thin lines (HL² fences for example) while the SSAA gives really good quality on there, and as the SSAA is not really expensive I can only recommend it. And finally the trees in Guild Wars don't flicker when you move around. Well done!
