I'm not going to link to it as the actual release should be today or tomorrow, but it sounds like arQon has enabled vertex lighting in the mod which is giving a big fps boost when used. Hopefully more mods as well as Raven follow suit. Once an official release is made I'll put the q4max server back up.

Screenie. I asked Tigre if he'd be adding this feature to baseft, he said it's not planned but possible in the future.
