i run a quad core in winXP 64x when i try to solve a RBD i see the that the task manager is using only 25% (1 cpu) .
Is there a way to use full power my cpu?
and when i render in mantra it uses 100% but seems kinda slow is there
some trick in the render ?
thanks for your time

Simulations can be quite tricky to multi-thread. (Some aspects of DOPs are multi-threaded and will use more than one CPU)

POPs is a bit old and has very little multi-threading (if any). However large chunks of POP networks can often be recreated in VOPs/VEX, and VEX POPs can be multi-threaded.
