There's really no reason to have a framerate over 60-70. Most developer's make that their minimum target, given you can't detect anything higher than that, anyway. Still, I guess it's cool to show off a 400fps framerate. The 60hz bug is alive and well on my end, and it looks fine. A lot of commercial titles don't run as smooth as my project typically runs,a nd I can't remember the last game I played(modern) that had smooth framerates. Of course, that is related to my system specs, too.
