DId you get this drop in fps recently or has it always been like this?
Are you running toribash 3.99?
Have you tried reducing the graphic settings under options?
Are your drivers up to date?
Have you tried reinstalling toribash?
What are the specs of your computer?
Need more info =/
Edit: Also check out this thread. It has detailed instructions for updating drivers, minimum requirements, etc.
