CounterStrike Source

[Jones]

Hey all, I've gotten Steam installed successfully and have gotten CounterStrike and CounterStrike Source on my comp, but CounterStrike Source has massive fps issues. Even when im still in the menu, the game slows down to an unplayable speed. On windows, the game runs fine. Counterstrike and Call of Duty works fine so im not sure why CounterStrike Source should have too many problems. Any ideas?
