FSAA is too much of a drain of framerate. I find that it's much nicer to just play at a higher resolution, and get more fps. The only way i'd suggest FSAA in OpenGL, is if you set the quality to the minimum-medium, and run at around 640x480-800x600. It really depends on how powerfull your system is. I can run at 640x480 max quality FSAA, and get around 100fps, but there are things that bring it down, and having non consisten fps is very annoying. FSAA isn't very great, unless you stop, zoom in, and stare at the edge of something. Extra eye candy is nice, but not when it slows you down a lot.
