I'm seriously in awe. I can't believe this works. SO ******* COOL.
Ok, so I started up BF3, the second level. I took this screenshot just before we hopped into the plane. It's a tad odd that it says 1818mb used considering I have 1gb cards, but my best guess right now is that it's counting 2gb as the total (even though we all know the usage is identical on each card). I'll have to add this to my GPU monitor if I can. So. Damn. Awesome!
