System slowness R18/3.06

[sdanaher]

Been experiencing system wide slowness, and lag while Cinema is running and after initiating a LV render. Even after stopping a render the system remains very slow and jerky (selecting menus, moving wondows etc), as if the gfx card is still fully occupied. Only fix is to quit Cinema. I have not noticed this before with Octane and this system but has started on the current job (3 different scenes).

Cinema's own interface slowness gets worse when multiple editor views are active. Switching to a single editor view fixes the slowness of the ogl interaction so I don't think it's the size of the scene itself (it's not particularly huge). There's also a long delay before the interface becomes responsive when switching to a single editor view from say a 4-view (or even 2 up). Things definitely get better when stopping Octane completely, but there's still noticeable lag on the system generally until quitting Cinema or resetting the editor views.

Render Priority is set to low. I've noticed Vram is reported as 812MB on the LV info overlay, but 264MB in the render log??

System is an iMac + thunderbox Titan X as host with 2 slaves in a MP 12 Core.

First try to disable monitor gpu for Octane rendering and check...

Do you do that by switching off the card in Settings>Devices?

Yes off.

Hmm, then it won't render at all, says no cuda device

Sorry that's correct. What happens if you don't use slaves?

[sdanaher]

no difference

How was that on 3.05.3? Try by disabling "texture cache". Btw you have one card on host and it can become very stressed if you have heavy computational scenes.

[sdanaher]

thanks, yes its the same setup I've used for a while, not had this happen before, even on much more complex scenes. Will try disabling texture cache.

I think it helped, but its still slow. I found that I had a cloner with instancing not enabled, that seemed to not be helping.

Also now having a problem where the editor view you're working in does not update but all three of the other views do. No matter which of the 4 panes you try to pan, rotate or move an object in that'll be the only one which does not respond. Sometimes they go black during an edit too. Had this before some time ago without figuring out the cause, its back again.
