since updating to windows 10 i have very weired behaviour of jit.grab: sometimes it works just fine, but then suddenly my framerate drops from a (theoretical) 400 to about 5 fps randomly (and might as well stay like that for a while but might also return to normal after some time). does anyone know something about this?
on windows 8 my patch worked just fine. with windows 10 this happens with jit.dx.grab as well as with jit.qt.grab and also with all max versions 6 and 7, both in 32 and 64 bit. also it makes no difference if i use the built in camera or a blackmagic card. however as soon as i replace jit.dx.grab eg. with the camera output of a kinect everything works as it should.
i did not test this thorougly but the bug might be somehow related to jit.window because if i delete that and send the output to a jit.pwindow instead, it seems to work fine.
