Hi
some changes in the newest v12 daily, makes the interface of c4d stalls or freezes, i almost cant do anything while i render, even with ipr. cpu usuage is very high near 100% even on ipr which should not take all cores.
any idea? maybe the lastest optimisation for many cores machines did shoot over a bit ? 
first i thouhgt it did freeze, but seems is only using the cpus so extreme.
it is even hard to press the stop button on ipr
EDIT: after c4d restart it seem sok again for now. if this happens again i post it here.
