Hi Jan, The thread has to have it's affinity set for it to have an affinity to a cpu core, so you if are creating your own threads and not setting their affinity they won't have any and should more from core to core according to what the OS decides.
The only thread I expect will have affinity to a particular core will be the viewer ones. Using Qt threads it sounds like is not implementing affinity so rather than working as expected it really just isn't working as it should. It rather seems like your expectations are a bit off and the OSG was doing the write thing in the first place. Robert.
