Sorry for late reply. Kurt, if your frames are dipping below 30 then the console command won't work. But anyways you have to enable console from the options.
use '~' key on the keyboard to enable console. Type, com_maxfps 60 [or anyother desired value] There could be number of problems, you just have to figure out what has changed since your last normal gameplay. Regards -- INTEL 9xx SOLDIERS SANS FRONTIERS
