Another performance thing I've discovered - but not nailed down. On my laptop, I run 4 threads. In certain situations, Poser stops using 100% of my CPU - it drops to 3 or 4 percent. This means a render takes hours.

I've found that dropping to a single thread will fix this. That means on my dual core I never use more than 50% CPU, but at least it stays at 50%, which is much better than 3%.

I have no idea why this happens. I suspect some mistake in Poser where the multiple threads are all curteously waiting for each other by mistake, and none of them do any work for long periods. By using only a single thread, any attempts at multi-thread coordination are skipped and it goes full speed (but uses only half my dual-core.)

Has anybody else seen this?

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
