[Q2]

Hi everyone

Rendering a 10000x10000PX scene in maxwell render and my PC is only using about 5% of it's CPU power. Takes forever to get started and even my Mac Studio rendering the same file gets a much higher benchmark. What is going on? PC benchmark 291 vs MacStudio M1 benchmark 895!!!

Any ideas? Maxwell Studio and Maxwell Render are running as administrator . Does anyone have an idea what is wrong here? Cheers Q!

Here is the Maxwell Benchmark Test Render... USING ALLDA POWER!!!! .... WHY?

We have in our Studio a 3990x
never had a problem like this.

We noticed ( sometimes ) a reduced workload using the FIRE preview.

1) have you checked the Priority before launching the rendering?

Usually if you’re not working on the same machine even choosing low priority, the Rendering engine will work at max frequency and max utilization, but if you’re working in other Software while rendering, choosing low priority, could potentially reduce the cpu utilization for Maxwell render.

But 5% utilization is anyway too low.

2) check if this happen with ALL your project

3) check if this happen within the already included scene in Maxwell Render
( Maxwell render demo scenes )

3) can you zip and upload your project with WETRANSFER so we can try to check it out?

I suspect that either in your host app or Maxwell it somehow got set to use one thread. Make sure it is set to 0

I had the same problem with my new DELL Precision 7875 AMD Threadripper machine using Windows 11.
I had to set priority to NORMAL to use full CPU capacity!

Figured that out just by chnace right now!
I was going crazy..

On my previous INTEL PC with Windows 10 it was BELOW NORMAL and I ha no problem..
(also -1 CPU thread to work in Rhino).
Great workflow and up to 5-6 cuncurrent rendrings in the backgorund.

Now if I don't set priority to NORMAL as soon Maxwell is not in foreground CPU goes down to 5%!

very odd!

it happens to me every now and then, also today
usually it means that there are a missing texture / missing MXS reference / problem with a network path.
most of the time if it happens maxwell will stop and prompt you about a missing file - however I found out that every now and then it will not stop and render very slowly.
also a bad object can cause these (like a bad conversion of a pillow from 3ds max to maya, for example ...)

yup, found the culprit of the day: a decorative indoor plant from 3ddd. deleted it from the scene and PC runs at 100% as always.

I found a good setting:
My prority is now set to NORMAL while CPU Threads is set to All -2 (as I have 1 CPU with 16 cores and 32 Threads).

Renders now go at full speed and the PC is only sometimes slowed down..

Mostly I need to either setup other Maxwell Scenes, model or export from Rhino 8 or start Photoshopping renderings that are already done with this blasing fast Threadripper.
Thes apps usully need only one core.
