Empty patch runs on 64fps only. some windows7 issues?

boy, that’s strange…
since this morning my vvvv runs on 64 frames only. even a completely empty patch with a lonely “timing” node only performs 64 frames…
when I create a Mainloop and put it to 60 fps the framerate drops to 32 fps. mainloop on 30 --> empty patch runs on 21fps.

until yesterday everything was fine running on 120+
I’ve checked directX and slimdx and rebooted several times but still 64. Also in the taskmanager everything looks fine…

my system is windows7 64bit running on bootcamp.
I’m sure I’m doing some very stupid mistakes but I do not have any idea which. I’m not new to v4 but I switched to windows7 not long ago…
thanks folks…

haha, bingo!.. I even got the 64-32-21 fps identical.
thanks master… my day is saved.
