some commands that give you better fps are locked atm, like violence, corpses and so on, but try GeT_RiGhT's cfg and see.
I used f0rest and Xizt's and I had good fps. Just try. I downloaded some top CS:S players' config too, to see some commands and I did my own config. It's kinda nice but some things need to be changed. Waiting for the final game to have a complete fps config
