[Max] Bug Reporting / Re: Scene has slower viewport performance with Corona 11 than Corona 10

« Last post by Aram Avetisyan on Today at 00:15:37 »

The thread above has a reply for this issue as well, but is for general 3ds Max UI sluggishness, with or without the combination of Corona.

This will be the specific thread for this issue, as a bug report (for the sake of finding it better) - scene has slower viewport performance with Corona 11 than Corona 10.

Hello Aram,

I just wanted to confirm that I tested my problematic scene with Corona 11 HF2 in both 3ds Max 2022 and 2024, and it seems that the problem is now resolved. The viewport behaves smoothly.
Thank you and the entire Corona Renderer team for listening and support.

Best Regards

@besto
did HF2 solved your issue?

We are very happy to hear that and thank you for your kind words!

Thanks for the test and reporting back.

Can you please try one last thing: try with 4K Cache (or UHD Cache) as secondary solver and set it to, if not already:

Precomputation: Try to load + append
After render: Save to file

Let's see if this brings improvements.

[Max] Feature Requests / AI Post processing

« Last post by n.merazzi on Yesterday at 23:14:34 »

In Post processing tab, We could have an AI tab to improve our images.
For example I'm using KREA Enhance at the moment to improve my images and get ideas to work on photoshop.

If we could have something direct on Corona, it could be a game changer.

Usually, I like to change people with AI, but for planting is really nice as well.

Here is example of DDR5 RDIMM (the 'R' - Registered, is important) : https://www.kingston.com/en/memory/gaming/fury-renegade-ddr5-pro-rdimm?speed=5600mt%2Fs&total%20(kit)%20capacity=128gb&kit=kit%20of%204&dram%20density=16gbit&profile%20type=amd%20expo

It's unfortunately whole magnitude more expensive than regular DDR5 memory. I personally didn't know this information few weeks back :- ) I don't really keep up that well now that all PCs are fast and I am not upgrading very often. I know a lot about children bicycles though.

There are also many generic variants that go for cheaper (here is example from few pages back from this thread, I am linking the 256GB version but I am pretty sure there is 128 as well.

Alright, thanks!

I'll check this out.

I'm certain he'll tell me you're wrong, but I trust you 100% so I'll press him on this!

Ah, I see he's already changed it to: Kingston DDR5 Fury Beast Black 64GB(2x32GB)/5600 CL40

Better?

(Your knowledge is simply amazing, Juraj. I cannot begin to comprehend how this has all not only been amassed but retained!)

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

Yep, we are aware of the patterns - I say patterns as we do know there is more than one thing going on.

TRX50, well, all Threadrippers (X and WX alike) now require Registered Memory modules same as Epyc. So that listed memory will not work.

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...

Thanks Aram.

Flickering gets worst with Path tracing in both primary and secundary.
Attached a test (notice how the flicekring only occurs in the water. The stone areas are flicker-free.

Sorry to go a little off-topic here;

I'm just ordering a new PC and the following components have been selected by my guy.

I've already decided to upgrade to RTX 4070 12GB and use water-cooling (LIQTECH TR4 II Series 360mm Liquid CPU Cooler) instead of the air-cooling listed

Any thoughts? Anything I should be weary of?

Thanks!
