Feral Heart

ok ive played fh for a while then i had a little problem with folders... redownloaded the game a few times, patched it, folders back. But now when i play it, it freezes ever second and afterward gives me another second of normal non lag moving then it freezes again. I played for a while trying to ignore it but now its just pissing me off. Can someone tell me how i can get rid of this stupid glitch thinga majig?
