Sure do. It has some minor problems though, but I am sure you'll figure out how to use it properly. I have attached a program which will take up lots of CPU power, and you adjust based on percentage you want it to use. I had about 70-80FPS ingame, so setting it to 75% made it for down to 55FPS. Fiddle around a bit with it and I am sure you'll get something which works nice. It seems like it will slow down the system a little bit after use though, but I am not certain and it wouldn't make sense really. The program is freeware.
Oh, and don't blame me if anything goes wrong (I really doubt it will tho)
