I just increased my FPS using this custom map

^and it feels great, I could care less about the visuals, but finally I guess I'll be able to get through without any fps drops anymore.

This is how it looks.

I'm actually liking my fps going from 14 to 30 =D

EDIT- This is the Extreme Low Quality custom map, there is a low quality map too which looks better.
