[Max] Bug Reporting / Re: Very slow geometry phase 10x slower than old pc

« on: 2024-05-02, 20:39:42 »

There seems to be a pattern here with high core/thread machines -see my threadripper post. My cinnebench scores were great on a 64 core machine and disappointing real world performance with corona 11...

@maru Do you have 3990x and 3970x machine on latest build Win 11 and latest bios/chipset drivers etc..to test these files?

I can't share the files due to NDA. So I will have to create a test file to upload..

Have done a few tests..and by knocking out Corona Layered mat, the 64 core machines pull away and out perform the 3970x 32core machines. Interesting to say the least.

Hardware / Re: RTX 3090 & RTX 4090 - any difference in Maxs vierwport?

I can confirm there is little difference if any between Quadro RTX 4000 (old) and a 4090 -we have both. Mat editor and corona menus are still slow and laggy. Cheers.

Have done a new local render (all assets local) and the 3970x and 3990x are neck and neck for render time. Something is not right. When you render a white model the 3990x pulls away and is much faster. I have noticed that this has become an issue since Corona 10.

Try a local render of a scene that you can share. We can compare our times and see where the issue is. This will also rule out if it's any issue through network rendering.

I'm assuming all bioses are updated and you're running RAM at default? Did you build these systems yourself, or are these pre-built?

Prebuilt by Scan here in UK

I have tried standalone and the results are the ~same. Yesterday I reinstalled windows 11 and installed everything from a local admin account to discount any user/group policy issues..same result. I use Pulze render manager for network jobs, but I don't think that's the culprit. Interestingly, if I render a chalk (white mat override) the 64 core machines do better than the 32 core machines!

pulling resources from a dual epyc server (ms server 2019) -the drives are all nvme 4.0 and the connections are sfp+ 10gbe -across network with average transfers ~1GB up and down. The common factor is 64core machines (multiple) are being outperformed by 32 core machines (multiple)

The benchmarks are as normal with the 3990x and 3995wx pulling away. But real world is a very different story. I've even tried standalone render and the 3970x machines are faster on most projects. Temps are all good with all chips at spec frequencies during renders.

Going to go back to this again as there's something wrong. Recently bought another 64core threadripper 3995wx (used) to complement my existing 3990x and 4 other 3970x machines. It really annoyes me that all 4 3970x machines are way faster than the 64 core machines at rendering!! All latest drivers, os builds, bios, Corona 11 (+hotfix), 3dsmax 2024.2, 10gbe lan, AC on all machines. There is something going on here as we've now tested this setup with win 10 and win 11.

[Max] Bug Reporting / Re: Corona_Out_Of_Core_Texture Trojan Win32/Sirefef!cfg

« on: 2023-08-16, 17:31:32 »

Hi it no longer exists. I have re-saved the textures including a .exr as jpegs in the job folder. If I repath back to the megascans folder Ms defender immediately flags the Corona textures cache. The megascans maps themselves aren't being flagged. I'll upload when I get a chance. I don't think it's a trojan but it will break a scene file without isolating the maps and saving them as jpegs.

[Max] Bug Reporting / Corona_Out_Of_Core_Texture Trojan Win32/Sirefef!cfg

« on: 2023-08-16, 15:31:59 »

Hi. I've just  downloaded a surface map via MegaScans Bridge to 3dsmax (2024.1) and Ms Windows has thrown up a positive threat identifier in \CoronaRenderer\ImageTextureCache\Corona_Out_Of_Core_Texture Mip_Map_6.data. Really weird and never had anything like this before. It's most likely a false positive and I know others have had issues with Corona_Out_Of_Core_Texture. Anyone else had Sirefef!cfg flagged?
