Possible refund?

I'm all for supporting smaller devs, but I recently got this game on the steam summer sale, and well, I've played every other game ever on this computer with no issue, but with this one... well it's so choopy and my FPS so low that its pretty much impossible to play. I was wondering if there was any way to get a refund?

dxdiag incase anyone knows if there is a fix for this issue. It's certainly a bummer to have gotten a game and not be able to play it.
