image-lodbias is default but I wanted to see what image_lodbias 4 is like, and this is it. Urrrgly! If it wasn't for the text, it would be a perfect picmip replacement. See the 68fps on the second shot? If that framerate is possible, surely a lot more frames can be achieved on a faster system than mine when tweaked? Someone told me they had 100fps on a tweaked config.

This is on image-lodbias 1. After that, ( ie, image_lodbias 2) the text gets too blurry again). Conversely, the minus numbers sharpen it up.
