System Sluggish when Rendering - Affinity / Priority / Throttle for Enscape?

Enscape General
1

I am curious if others experience a general system slowdown when renderings with enscape?

I am running 1080ti.. (2 actually, but I realize only one is used) Cpu utilization is around 10%, and gpu seems to be around 5%, but my system lags when rendering. With vray, I could change the affinity to reserve processors for other work. With enscape, I haven’t been able to figure out why there is a slowdown or how to throttle it.

Thanks,

Chris

@renderwiz We render GPU and VRAM only. So maybe your screen gets updated sluggish when Windows tries to update the screen via GPU1 as well.

We don’t provide a functionality to lower the used percentage of your GPU.

=>But usually this shouldn’t be a problem.

Thanks for the reply… so your experience is that the system remains fully responsive while rendering movie files?

Fyi, I have noticed that simple scenes cause less sluggishness while more complicated scenes cause more. Gpu utilization appears to be less than 5% in either case but still causes the issue.

The GPU usage of 5% for both GPU’s seems a little bit too low. But the behavior seems normal.

I’ve filed your request for a adjustable usage maximum.

That would be great.

So it is normal to experience some sluggishness when rendering movies? I was asking to make sure I wasn’t missing something obvious that could improve the responsiveness.

@renderwiz when the resources are used there can always be some sluggishness.

I would like to report back that using EVGA Precision to lower the “power target” to its minimum has helped quite a bit. Any speed tradeoff is well worth it imo.

The system responsiveness is usually not related to the GPU. Therefore, you could set the task priority for Enscape lower in the (CTRL+Shift+ESC) which makes the CPU load balancing prefer other tasks. This could help i guess.

I do not see an enscape.exe under Processes… should I?

Windows 7 64bit

@renderwiz We’re using the process of the host application - Revit.exe/SketchUp.exe/Rhino.exe

Gotcha, I tried that and it does not seem to help… however as I mentioned throttling the GPU does seem to in my case. Thank you for the tips.
