Rise of the Triad Fps issues

Hello, I have been having problems with the fps being around 22 - 30 fps no matter what the settings are for the graphics. I can normally get pretty decent frames in other games on high or ultra at about 45+ fps. I have looked online but i can't find a solution that works. my specs are: 

Amd A6-3650 @ 2.8 Ghz 

Msi A55m-p33

Msi gtx 660 2gb

8 gb of 1600 mhz ram

any help is appreciated
