Tip for great anti aliasing

I'm a little lazy right now, but simply put use http://neogaf.com/forum/showthread.php?t=472941 to create a higher resolution than your desktop to scale down to.

PS: This guide is for AMD GPU's, not sure about nVidia GPU's.
I find the best image quality to performance ratio is achieved when downsampling 2560x1440 with 4x MSAA to 1920x1080.

Example shots:

Even if you don't find it to be much of an improvement in these screenshots, it's extremely pleasing to look at in motion.

Various notes:
  • This will obviously impact your performance
  • Can easily eat up a lot of VRAM if you are experimenting with even higher resolutions and AA levels
  • Screenshots with Fraps/MSI Afterburner will be in native res
  • Fraps doesnt' seem to support screenshots larger than 2880x1600, use MSI Afterburner instead
  • This is the only way to get super-sampling in OpenGL games (on AMD at least) as the driver doesn't let you force it
