Really interested in GPU using VFSU

Pixero

Here is a test render with Thea Presto AO. GPU + CPU.
I must admit I didn't put a lot of work on the materials.
I let it render for 39 minutes on my modest Macbook Pro laptop with a i7 and a Geforce GT 750m.

Resized from 3000pixels to 1600 to be able to post it.
Partial 3000 pixels wide render. Click to see it at 100%.

I had some time to check out your scene. I was able to render at 1600 pixels in 5 minutes. Then with saving the LC and IRR maps, I ran a full res render in just under 10 minutes: http://www.mediafire.com/view/qqdk52aq9ff998z/full-res-test.jpg
There wasn't really anything I needed to do with the scene. I dropped in my own IES files since it wasn't included in your download. I deleted some high-poly stuff just to keep the parsing times down and help with scene navigation. For those things, I would typically use proxies, that way there's no speed hit at all.
My suggestion: get vfs 2.0 and use DR on as many machines as you can.

yeah, check your materials. You probably have things like semi-glossy reflection or refraction. Are those blinds 2-sided translucent or is it refractive material? Optimized, that should be a quick scene to do in vray. (prob 5 minutes on my hardware.. [[OK 15mins, conservative]] . I have 46 cores with DR...)

Thank you guys so much for your time and effort to try my model. Those are fine renders.

From my side ,I happen to work with guys who do 3ds max and whose benchmark is Evermotion,

Honestly, I have to put in a lot to even try to match their results. VFSU 2.0 somehow is getting there. I have yet to see how Thea will perform.

@Pixero, 39 minutes may still be a little quite long for my boss, If we are to use GPU,
Then He would expect something like 3 - 5 minutes.

@Andybot, Yes Im immediately requesting an upgrade to 2.0 and as you say proxy the other hi poly stuff. your render is impressive for a 5 minute run, Is it done on one machine? Would I be able to cut that to say 2 minutes If I use DR on say 3 machines?

5 mins. is with DR, (46 cores, around 3.5Ghz average). If it were on one machine only, probably 20-30 minutes for the 1600 pixel render.

to get down to 2 minutes - you'd probably need over 100 cores available (or else render smaller!)

Thea Presto is much faster with a faster GPU than mine.
I know Solo has a Titan card.
Let's hope he gets time to do a test render to show what times are possible with it.

Will you send me the model as you have it set up already and i will test just GPU.

i would really be thankful to see. titan is one solution im considering. even for my personal use. Might as well be convinced to learn Thea

I tweaked a few materials, ran Presto for 18 minutes only GPU (did not use CPU and GPU as I wanted to test Titan on it's own at low priority)

Funny how in Thea4SU my card shows 4GB ram and not 6GB, is that a Sketchup limitation?

Pixero

It would be interesting to see how well CPU+GPU does.

Hi- res , clear, crispy image. At 18m 37 secs. That is impressive. Thanks for trying out.
Now I'd like to consider Titan.. and probably Thea too.

And I wish there's somebody who could tryout vray GPU . At least with these few infos, I can come up with a recommendation to my boss in terms of GPU hardwares

Thanks a lot
