Ok, here are some Quake3 screenshots with r_colormiplevels 1. All screenshots have 2x FSAA enabled. I'm not sure why the shots turned out so dark, maybe it had something to do with print screen.
edit: As is clearly seen, 0x+TS is not the same as normal 2xAF. 2xAF is better.
Screenshots to come later at 4x FSAA, and maybe some shots from either U2 or UT2003, although since I don't know if you can view colored mipmaps in those games it will be harder to discern IQ.
