Reactor calculations only use 13% CPU?

[Ky Lane]

So, I've setup a scene deforming a plane set as cloth to represent and opening/closing curtain. Theres alot of subdivs, so its alot to process.

 

However, as its now keyframing the reactor stuff, its only using 13% of the CPU (I assume just 1 of the 8 cores) and taking is sweet arsed time (been waiting an hour now, and only 50% of the way - heres hoping its right!).

 

Any ideas if I can accelerate this process? I mean, I bought 8 cores for a reason!

 

Thanks guys!

maybe we should take this to the autodesk people. the Playstation 3 uses all its cores in it's physics calculations.

Things like this are common in many software apps. Reactor either has never been written for multiple processors, or the old story.. the CPU needs to certain mathematical calculation in order, so only one CPU is utilized.

 

The later of the two I always felt was just an excuse to keep from needing to partially reinvent the process to use multiple CPU's.

 

In reality, I think most modeling functions in almost all applications only use 1 CPU. Though that may have changed.

Ask for the source and rewrite it multi-threaded? ;-)
