Want to get a better FPS and not lose any visual effects? Well, I found this great FPS script that I personally am using that takes away all the stuff you can live without and help boost that FPS number up some. I gained 15-20 FPS with using this script, it does vary from computer to computer! Check it out:

I saw an fps boost of anywhere from 10-30 depending on the map. I normally dont have any fps issues so this should boost anyones fps.
