What upgrade is needed to render 3D images faster ?

[doopydug]

Guys - I have a software package called virtual worlds for 3d designing bathrooms and kitchens.

The images below took over 4 minutes, each, to render and I wondered what would be the best components to upgrade to get that speed a lot faster

There is a little ray tracing involved too, I believe.

Current spec is Ryzen 2600X in B450 Aorus M with 16Gb 2666 DDR4 RAM and a GTX 2060

I would say that a rendering app like this would be multi threaded though?

I tried speaking to the manufacturer of the software but their tech dept were clueless

very nice
thats pretty realistic looking
not familiar with the software but
by upgrade you mean a component or 2?
or if it turned out way faster clock speed was the key then
you could change to a 5ghz intel set up?
and as always budget is important to know

i just bought the system at the end of last year as a complete build and really didn't want to disturb it too much for warranty purposes.

Budget isn't too important - just didn't want to go about making wholesale changes and wondered if there was an obvious bottleneck to the rendering process

Open task manager while it is rendering and see what is in use - with Windows 10's task manager you can get a good idea of GPU resources and the number of CPU threads in use, etc. (might have to change some settings to get the most useful metrics to show) and the balance of those should give some idea as to how threadable it is. (i.e. if it is only using 4 CPU threads heavily and the GPU is maxed out then a CPU with more cores possibly won't help while on the other hand if GPU utilisation is low but all CPU cores are maxed then it is more likely more CPU cores will help).

Good idea....

CPU Maxxed out right from the start - GPU varied between 10 and 40% usage - strangely, the CPU never went higher than 3.91GHz despite all cores maxxed out

Right click the Task Manager graph and set it to view Logical processors - just to see if it's using all the cores or not?

All 12 logical core processors are at 100%

CPU upgrade it is then

Threadripper time !!!

 

[doopydug]

Well, isn't that the definition of consumer support and all "troubleshooting" etc things?


Load is too heavy to boost all core clocks higher than that.
CPU's temperature or motherboard/VRM limits it to that.
100% means all cores/threads are maxed.

I see a competitor has a great deal on a Ryzen 3900 with a MSI X470 Gaming pro max mobo - is that a good one?

Was about to say, rendering can either be done via CPU, GPU or BOTH.

Also, programs can offer different plug ins to allow you to render off different hardware or 3rd party rendering engines.
If doing critical work you'd be rendering off workstation cards etc .

Also depends on cash you want to spend. Getting ram up to 3200hz will help . Switching to ryzen 3*** will also help greatly . Even 3700x would show a good increase without heavy cash ! Just update your bios first

Have gone with a Ryzen 3900 and 16gb DDR4 3600

Images with ray tracing ?

Keeping the RTX2060

Honestly I happened to see this and was curious because in most cases it's just more cpu and/or faster gpu (depending on render engine).

When I saw you were complaining about 4 minute renders I was like... you're complaining over 4 minute renders.. really.... I've had (animation) renders go into days lol. In the past I've had single frames take over an hour in some cases when you get the joy of raytracing and multiple different refractive materials etc.

That was a low quality render - the problem is we show them to customers in 4K and that takes a GOOD bit longer - feels like an eternity when you are sitting planning a bathroom or kitchen with a customer sat opposite you waiting for the screen to load. They don't hang around for ever you know- things to do - people to see.

 

[doopydug]

Maybe you need to look at different programs... I can't remember needing to sit around for ages when we had kitchen/bathroom planned in wickes/b&q (pc's weren't high end either)....

In all honesty if you want 'instant' rendering for clients you should really be looking at programs that support gpu rendering but it doesn't seem that the program you mentioned is even considering gpu rendering tech...

I have their software already - its a very poor quality image but it works for their market. When you are aiming for the quality market, you need a quality image and the low quality renders in my original post blow away the BEST that the wickes / B&Q software have to offer.

 

[doopydug]

Honestly if that image is indicitive of the images it puts out then that isn't any better than the ones I saw in wickes/b&q imo..... you might think otherwise, and that's fine, but I'm basing it off my own experience and my work in 3D design and rendering.

Yeah - I have the software that they have too - 2020 its called. I bought it because I was familiar with it from working at B and Q for a year so thought it would be the best one for me. When you use them both every day and compare them side by side, trust me , there is a huge difference when they are BOTH on their best quality settings.

As a wee update, I upgraded to a 3900X from a 2600X and popped in faster RAM 3600 CL16

CPU still maxxed out at 100% on every core but rendering time dropped by almost 40% I would say

Very worthwhile indeed.
