GPU benchmarks

In 3DS MAX, I get a terrible lag, unless I scale to 200% using Windows Scaling. NVIDIA says that 3DS MAX isn't 4k compliant, so there is nothing they can do.

I am using a AMD Firepro for my display and A GTX for compute on a 32 inch 4k monitor, I have no issues at all.

Well, that's the one I have. I was troubleshooting some 4K issues and it was mentioned that my card wasn't good enough.

What were the issues ? I'm using one of those cards in our studio for 4K TV.

Best performance/money is currently GTX970 in my opinion. It's not much more powerful than 780, but has more RAM and lower TDP, which means in simplification that if you render on it for full day it uses around 2kWh less electricity. And that's around 60-70 Euros less yearly assuming 50% load time.

Best,

the GTX780 is $335 on Ebay. Not a lot of RAM.

Is the GTX580 still the fastest? This seems like an old thread and the GTX580 has a very nice price tag.

I don't think so, it has been outperformed by 7x by a good margin.

I look carefully at it before investing in the GTX780, but the heat and noise kept me away.

Vray is faster than Octane, bought Octane, used it for six months, gave up on it. couldn't finish one project with it. I had some scenes where vray would clean the scene in half the time. Octanes material converter never worked, always screwed up 90% of the materials and I had to go through each one by one to fix them. And when you need support they are non existent, only other forum members ever replied to my questions. Support is one of the most complained about issues with Octane. I also owned Thea render, fast, support was good, there material system and preview was nice, (love the way you can preview materials) but crashed way to much to use for production.

Thanks for the feedback!

And +1 on having fast preview on the materials.

Thanks for that insight info!

I think the main thing we need to get from other render engine and that most people complain about is the material preview.
Corona and thea render have some RT render for previews and it makes a huge difference compared to max one

We need something similar

I don't, right now I just do some testing on some Evermotion archinterior scenes and wonder out loud how fast Vray GPU RT is compared to Octane.

Well, the only way to find out would be to test it out... the only thing to keep in mind is to use actual path tracing in Octane, and not direct lighting kernel...

Best regards,

Yes it's pretty cool

Don't know for octane VS RT, but LC helps a lot! And I can't wait to have IR on GPU as that's gonna be a even bigger game changer!

Indeed, but I get the impression from some of Vlado's post that he is more keen on optimizing BF than IR moving forward. But, yes, I saw that he will eventually do some work on it.

If you have a scene that we can convert to octane, I'll be happy to bench them out and see how they compare to each other.

Damn, Stan. 7 Titan X's! That is some serious power right there.

One question for all of you: How fast is the Vray RT GPU with Brute Force compared to Octane?

I know that Vray has the benefit of LC too, but can Vray RT GPU compete on speed with a highly optimized BF GPU render as Octane?
