Horrible Framerate, cant figure out why

[Lambach]

Hi! thanks both of you for getting back to me.
Its a desktop, about a year old. Never top of the line, but it runs LOTS of ther games with no problems, so I didnt check min requirements. Ive actually never had a problem running any game before. I just turn settings down a bit and Im good to go. I'll try turning down resolution. WIll that make the game teeny on my screen?

edit: run as admin fixed the new problem. Now its back to just fps.

Thanks again for your help.
