I ran a check with Portal, which seemed like a pretty processor-heavy game (My desktop, single core 3.0 ghz, 2 gigs of ram, Radeon 9800) runs it moderately well, so it seems like there's some sort of problem on this computer's end. Ran a check with AVG, nothing came back as far as viruses go. Maybe it's a Vista issue.
Edit: It would seem the video processing is a little bit lacking as far as shaders go, but if anyone's seen blackshades, the characters are like 3 polygons each and I'm pretty sure it employs no shaders; and Phun is 2D and I've turned shader use off.
