I am searching the possibilities to upgrade my workstation with a graphics card that is sufficient for running Pro Walker on the GPU. So far I understand that the card should have/support Iray drivers.
The cards mentioned on http://podiumwalker.com/iray-hardware.php are hard to get here or quite expensive.
I'm looking at this: https://www.alternate.nl/MSI/GeForce-GTX-1070-AERO-ITX-8G-OC-grafische-kaart/html/product/1338281?lk=20214
My questions are:
- If I buy a random Graphics card with a Nvidia GTX 1070 GPU, will ProWalker run on it?
- Is the Iray driver bound to the manufacturer of the graphics card or the Nvidia chipset?

(I mainly want to do still visualizations)


specs station:
Dell Inspiron 3847  (never gonna buy a Dell again..)
Windows 10 Home.
Intel Core i7-4790 3.60GHz.
16,0 Gb RAM.

1. Yes, a GTX 1070 will perform well for still images.
2. Bound to the NVIDIA chipset, manufacturer won't matter.

I have a GTX 1060 in my laptop, and it's still a very good user experience.  Because of NVIDIA's denoiser you get a very good idea what the image is going to look like almost as soon as ProWalker loads.  So the major difference between a 10 second render and a 3 minute render is edge clarity:

10 seconds

60 seconds

180 seconds

For interiors or models with a lot of artificial light the performance slows down, just like it would with Podium.  The denoiser isn't as precise, and can yield artifacts that soften edges in unnatural ways.  You can sort of see this in some of the 30 second tests that Zeus has been posting, though even with the artifacts I think they're very impressive for the render time.

I sometimes like to turn off the denoiser and use higher samples.  It takes longer but I think a little bit of noise is more appealing than denoising artifacts.

For bright exteriors like this though the denoiser is extremely effective, and results come very fast.

This is an example of the denoiser starting to struggle once artificial light is introduced.  See how the tiles on the pool are pretty clearly resolved with just the hdri background:

[afternoon-02-nolights] 

Once all the artificial light sources are introduced, parts of the pool start to get blurry and would have needed additional time to tighten up:

[syferfontein-clear] 

I don't remember exactly but those were both probably between 5 and 10 min on the GTX 1060.

Thanks Justin!
I'm am a little confused about the Iray drivers/plugins. Because when you search on Nvidia.com for Iray, there's little to nothing to find about this subject. And when you find something about Iray it seems to directed to software developers.
https://www.lightworks-iray.com/about-iray
So if I understand it well Iray is just a feature on these Nvidia chipset that can be integrated in 3D software?
And my only concern has to be getting the right hardware. 

I'll still be using Podium next to ProWalker, but now I losing big time with experimenting.

Iray is a render engine produced by Nvidia, which is coded to make best use of hardware acceleration on its hardware. It's only available for developers, it isn't a consumer grade renderer.

My Windows laptop has a 1070GTX. You do need to update the Windows Nvidia drivers for the chipset periodically, but other than that, it's simply a matter of install ProWalker, render, enjoy 😉

Yeah, the Iray render engine was written by Mental Images at NVIDIA, but Lightworks wrote the API/SDK and acts as the point of contact for third party developers like us, Autodesk, Solidworks, etc.  This is why their page is easier to find.

This is NVIDIA's official Iray product page: https://www.nvidia.com/en-us/design-visualization/iray/

But like Jim said, this page is really targeting potential developers, not consumers.  We haven't fully integrated every single feature listed there, so reading detailed information about things like Material Definition Language and Light Path Expressions isn't really relevant to a potential ProWalker user.

I'm going to update my workstation with a GTX 1070 and replace the power supply at the same time; this card consumes a whopping 150W.
Add a SSD to complete the upgrade and then I'll be back to buy ProWalker. [smile]

Nice! Get a PCIE SSD if you afford one. They are a lot faster.

The GTX Driver site is here - https://www.geforce.com/drivers/
It's a good idea to periodically update your GTX drivers.  In V1.1.7, there is an updated version of Iray which may require updating your driver.

Saw this article as I was looking for some information. Most of which are already answered by team here.

Some of the points might be helpful for any other newbie  .

That article is great on the hardware, thanks a lot for sharing, I'm sure lots of people will find it very helpful!

Where I don't think it's as good is on the 'build it yourself' section.

I built all my desktop machines years ago until I switched to working on a laptop.

The reality is that all the major manufacturers buy their parts in bulk far cheaper than individuals can. Sure you do pay a premium for having a stock machine, but with that you get support, a warranty and a website with all your standard driver details - if you choose the right manufacturer. The likes of Dell and HP are pretty cost-effective for the specification. There are often end of line sales, which get you last year's model at a big discount.

If you build a machine yourself, you have to mess around with chipsets and drivers, and the inter-compatibility of everything. In theory everything ought to just work. In practice however you may experience problems. If that happens, fixing them can be tedious, time-consuming and very, very technical. Most of us just want to render and don't want to mess around with this stuff.

I would never build a machine again. It's not at all difficult in terms of hardware, it's the software and configuration that gets both complicated and time-consuming. Even the business of formatting the hard drive and installing the operating system and all the various chipset drivers can be tedious when all you want to do is get proper work done. It can take 2 whole days before you get to the stage that is equivalent to having unpacked your HP box and connected everything up. And then you need to back up all your chipset drivers somewhere safe, which most people will forget to do.

If it goes wrong, you need another machine to trawl the internet on various forums to find out what the hell has happened, and how to fix it. If you really enjoy this stuff, great, if not, buy an HP!

you are right about branded PCs advantages... especially when you don't backup drivers or make a system image backup when you get new gig.
It was more of a reference check .
