2.74 not using all CPU cores when baking rigid body physics I noticed during baking physics (with 2,500 rigid bodies in a solidified cylinder) that, instead of using all 8 cores on my AMD FX-8150 CPU, it maxes one out at 100%, but then passes the baton onto another one, which goes at 100%, etc. but never seems to use them synchronously.



Baking takes a while with that many rigid bodies; is there a way to configure Blender to use all 100% of CPU when baking physics?

(Running Blender 2.74 x64 on Ubuntu GNOME 15.04 x64)
It looks like this is a known limitation of Blender (both the past 2.74 version and the current 2.76, at this time). The Cycles engine just doesn't (yet) have multithreading capability for baking rigid body physics. (Possibly soft body physics, also, though I haven't tested.)
