Motion blur is gorgeous when running at 75 fps. It's done just right. If you're averaging 30-40 then sure it's a mess

at 10 fps it's below a mess, it's just downright headache-inducing :p
Yep. and at 640x480, it's downright head-exploding. I'd rather stare at a strobe light for an hour than to play 10 minutes of it like that.
