i experiencing some problems on a windows 7 64 bit machine.
windows gets totaly unresponsive when a frame takes a while to compute (eg when reading big files / creating meshes). cursor still can be moved.
the problem does not occur on my 32 bit system.
i allready tried to change priority or isolate vvvv on a specific core via task manager but also via SetProcessAffinityMask.
what do you think?
