slow render times in 9.5
Hi,
I’ve just upgraded to 9.5 from 8.2. I did a fairly simple text animation, and it took quite a bit longer than 8.2. So I did this test. I created a sphere in 8.2 and 9.5, I applied the default brick texture, and put 2 spotlights with soft shadows in the scene. When I render the frame in 8.2 it takes 1 sec. When I render it in 9.5 it takes 3. This doesn’t seem to make sense? I contacted Maxon, and they said because of the new architecture, there is more for the CPU to do, so there may be longer render times?? I’m really disappointed that what took me 20 minutes before is now taking me over an 1hr…All that and the upgrade was $1700.I hope someone out there can shed some light on this, and maybe point me to something that could be causing this. I’ve checked, and all the prefs and project settings are the same??

Hm, i created a scene from your description and rendered it on the same machine with 8.207 and 9.521. In both cases i got two seconds of rendertime for 1024×768 pixel image. No idea where the difference in your scene comes from.

rendered scene on Mac to full screen editor window – v8.2, v9.1 and demo v9.52
all were the same times

Very strange.
But if you want to see where 9.5 shines, try the comparison with area shadows.

Hey,
I think I found it….
In the prefs, Common,
Render Threads was set to 1 (No MP) instead of optimal…
When I changed it to optimal, it rendered the same as 8.3…..
Looks like that would do it.
Thanks all.
