Do you get smooth material editor? Switching CoronaPhysicalMaterials? In and Outside of Interactive Rendering.
I am pondering buying one just to test how much better it works compared to Threadripper.

[Max] I need help! / Re: material editor SLOW - i think its a CORONA issue?

« on: 2024-09-05, 13:18:35 »

I will oppose all the advice in this thread, because I can already tell you, it will not help. Any big-PC (Threadripper, Xeon, etc..) in high-core version, is pain like this in material editor unless as you correctly shown, you use native Physical Material.
Corona, will have super slow material editor in any remotely sized scene. And it's not snappy even in completely empty scene, unlike native.

This has absolutely nothing to do with proxies. This is technical issue on Corona's side that they just don't care about. I guess majority of users aren't on 64-core machines.

BTW, my settings:
Standard viewport (so no HQ)
Every big mesh is proxy. (most of long opening is due to bugs like "corona assets" etc.. and similar stuff, having proxies makes scenes smaller, but it hardly makes difference in opening after scenes start to feature bloat).
Viewport texture settings 1024px for all 3 types(laughably blurry, so despite having 16GB of Vram, I only use like 2GB per scene because otherwise everything will be even slower).
Basic material editor for editing materials. I only use Slate to create them, but because it's so slow, all the little changes (changing IOR 10perc. here or there, etc..) I do in basic.
All textures mapped locally, on local disc with exact paths.
No plugins whatsoever. No ForestPack, no nothing.
It doesn't matter which Max version. It's the same as long as I can remember. Really makes zero difference.

It's not anything else, it's Corona. Yes you are correct.

This does in no way help with slow material editor, and esp. slow material editor during IR. That's like unusable, I waste like 90perc. of my time and 99perc. of my mental health waiting on shit to unfreeze.
It's what it is :- (.

If it's really all because of QT, then that should have been tried ages ago.

One thing I never tested, if it's connected to materials being applied to scene ( and/or additionally, having "shown in viewport"). So I will test:
- disable show in viewport in big heavy scene
- dis-apply all materials (I don't know, apply them to single box and hide it) just keep big material editor full of materials.

It looks solid. The retailer doesn't specify the memory, but I hopefully that is RDIMM (Registered ECC memory), which Threadripper now requires, and makes like 50perc. of the build price increase.
Threadrippers have become more expensive themselves, but the RDIMM memory is big part of it.

I believe the 32-core 7970X to be the sweetspot. All the cost that RDIMM + Motherboard eats up makes the 7960 quite poor value. If you're already spending 5K, might as well get the 32-core.
It's also the best performing one for daily tasks outside of pure rendering performance.

It's still worth it if it's the main PC for both work & rendering. But if you have rendering farm, I am not so sure anymore.

Nothing is similar to disabling hyper-threading :- ) But, in September (or +/-) Microsoft is rolling out Win11 update (24H2) with new scheduler, the OS part dedicated to allocating threads correctly. It might help the situation a bit, since scheduler is the part making most issues with high-core machines.

But given the prevalence of this behavior there probably isn't anything more to do.

Maybe the issue is just 3dsMax or Corona and nothing can be done at user level.

My main goal is to achieve a responsive 3ds Max viewport and fast interactive rendering within Corona.

I can echo everything Nejc said. But in particular for your above request, run away from 3xxx Threadrippers :- ). Their performance in responsiveness in Max/Corona is questionable, particularly the high-core (64) models. It's debatable how much of that is platform, the CPU, the Max/Corona architecture, Windows Scheduler, etc.. the reality is it's just sluggish.

32-core 7970X would be the best for the particular task.

Overall, this increase in price would be minimal compared to the rest of the components.

Exactly! People always try to save money on PSU, arguably the single most important part of PC that can save you from losing hours of work and your house burning down ;- ). Not being sarcastic, for workstation, it's always good idea to just get the best PSU and sleep soundly.

There is no downside to having Platinum+ 1500W PSU from big boys like Seasonic, BeQuit, SuperFlower, EVGA, Corsair, etc.. except the cost. But for Threadripper/Xeon builds, that cost is fairly small chunk of the overall build.
For <32- core & sub/= 4080 type of builds, 1200 Watts is reasonable choice. For 64-96 core + 4090, I would opt for 1500 Watts PSU.

There really is no easy way to answer that :- ) You posed the questions and partly answered yourself already. It's just too many choices and variables with laptops unfortunately.

The more all the features aligns, the more expensive it gets. "Buy once, cry once" I see quoted fairly often on internet today :- ).

You always overpay with laptops. They're just damn expensive today.

Ignore online PSU calculators, there are many more aspects to it than that, biggest being transient spikes and PSU current protections.

In short, you're PC can consume just 800W, but the GPU alone can for split-second consume 400-600 (depending on GPU tier) and trip the PSU.
Good PSUs allow for over-draw, but high-end ones can also be very protective, Seasonic in particular.

PSU also run at maximum efficiency at around 50perc, and most of them will run passively (fanless) at that point.

So 1200Watt is reasonable default choice for workstation today.

In laptops, performance between different laptops with same chip can be up to 50perc. It also fluctuates much more depending on conditions.

Different laptops provide different amount of juice and cooling. But majority of laptops outside of boost only provide around 50 +/- Watts for extended duration (rendering, etc..) and that makes it almost impossible to distinguish between different CPU models.

There is often very little benefit to upper tier of CPUs/GPUs in laptop, there is only so much the tiny body of laptop can cool. With GPU you're at least getting more VRAM which is always valuable, but with CPU the top models are almost useless.

The AMD one is bit faster, but much more power efficient, so it keeps high performance in almost any chassis. It's definitely better laptop chip.

There is no difference between 13th gen and 14th gen Intel CPUs. It's matter of statistical error, +/- 3-5perc.

My opinion is to stick to "big" laptop CPUs, such as Intel HX and AMD HX, but to get them in slimmer, portable body if you want the laptop to be more universal. So for example something like Razer Blade 16.
I think most Legions are decently portable, not as good as Razer, but not as bad as for example my MSI Titan :- ). The Legions are very popular choice for past 2-3 years so I think most of them are very safe choice.

Buying lower-end GPU like 4070 model and upgrading memory and SSD yourself afterwards is the right way to go unless you have unlimited budget.

Pay good attention to display options, with gaming laptops, sometimes there are multiple without the vendor even specifying. For example CPU option A will get 2560px with only 250 NITs, but CPU Option B will automatically upgrade to 400 NITs brightness display. It's really sad how complicated this can get. It's good to double-check the exact configuration in reviews on https://www.notebookcheck.net/ . The website is bit B-tier news aggregators, but they have very detailed laptop reviews and they check in detail the display, noise, etc.. which other websites don't.

You can't really mix ram, I don't think your existing 3200MT/s memory is DDR5 which is required for current gen platforms. It's best to just buy 2x32 GB or even 2x48 GB DDR5 in SODIMM form factor. Retail price such upgrade is +/- 300 Euro I believe.

Laptop is perfectly fine for 24/7 workstation nowadays, but it require some specific setups often (laptop dependent) to optimize the performance for particular task, as laptop cooling and power system is shared for both CPU+GPU together and majority of gaming laptops come setup to favour GPU performance. So by default, they will for example allocate only 50 Watts for CPU and 150 Watts for GPU which will be sub-optimal for Corona.
Quite a lot can be written about this that I don't really have much time but there are laptop forums such as https://notebooktalk.net/ where people go in-depth about it.

Hardware / Re: Computer for Corona and 3ds Max

« on: 2024-06-10, 23:24:38 »

3dsMax doesn't require strong graphic card for modelling. The only limitation is GPU memory (VRAM), which gets used for showing textures in viewport which is unrelated to rendering. 3dsMax being outdated doesn't use compression and you quickly run out of memory and then speed of viewport drops to like 1perc. As long as you use 1 or 2K res max viewport you will be fine with any GPU on market that has 8GB of VRAM.

So powerful CPU and plenty of memory is all that's needed for Corona indeed.

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

« on: 2024-06-06, 13:48:16 »

I am watching this with interest and I have some partial off-topic note. The up-coming Windows build, that will be public in September I think, but is already in fast-track beta public test (not sure which channel that is but probably ISO is available to everyone), 24H2 comes with completely new (process/core) scheduler. I do wonder if this might help our situation as well? At least a bit?

I am debating whether to test this myself, but I don't have much time or patience currently with very busy life.

The worst performance with high-core machines in general work is 3dsMax/Corona while doing IR. The rendering performance is as expected (the Ray/s metric), but every other process (Material editor refresh, Precomp phasing, etc..) is perceivably slower at same time.

Once again, not to de-track from above issues, just wondering if it could be additional piece of puzzle. Windows Scheduler was always big weak point for high-core machines.
