Try (sync 0) on your jit.window. If set to 1 rendering locks to the screen refresh rate, which is likely to be 60fps. Apparently discrete and integrated gfx have a different default state.

Thanx, i was experimenting with that right now, as it turned out, it's nothing to do with the speed of the card, the 60fps is some kind of upper limit only, if both car goes under (due some more calculations) then the GeForce performs better...

But still could't override this limit, the sync is not changing anything while running on GTX660 if i turn it off on jit.window... but at least i see where to look for it now! :) thanx!

do i make it right? just it still doesn't go over 60fps...

That runs at 200fps on my GTX660Ti under OSX10.8.2. Try sending the message (sync 0) to jit.window. There was a bug in an earlier version that wouldn't let you set it with @sync 0, though it looks like you're running 6.0.8 which should have that fixed.

You can also try setting it on jit.render instead of jit.window, though that's supposed to be deprecated.

thanx again! Neither sending the message to the window or render worked...

I checked the NVidia control panel and VSync is set to "application decide"... So i guess Max should be able to set it, althought when i've turned off VSync in the NVidia control panel and restarted Max, it worked :) But i had to restart Max...

Anyway it's solved thanx, even if i don't know why the attribute and/or message is not working inside Max!

Thanx again for your help!
