Interactive Render uses all cores, but 'Render' using only 50% of cores

Corona Corona for 3ds Max Help Required

Both are set to use all cores.

If I could change the Interactive Render resolution to 1080p, that would also be good.

thanks.

Not good at explaining this, try another way.

Why does IR consistently run the processors @ 100%, but when I Render, it only runs them @ 30-50%.

Does that make any more sense?

Check how many threads you have allocated to rendering, in the main render setup dialog. The default is 0, I think, so all threads should be in use. This is a separate value from the threads to use for IR, which should default to -1 (so it uses all threads minus one).

@atelieryork, Both set to 0

This problem occured to me to. Suddenly Corona uses only 50%, any idea for a fix?

Hard to say. It could been my too O.C’ing, or just updated the build.

It seems to be Siger shaders problem. Anyone else experiencing this problem using Siger?
