Octane Render 1.022 beta2.2 RC3 available [obsolete]

[RK-art]

Now I made some tests, comparing the same .obj-scene between Octane and Maxwell 2 , both rendered the same times with daylight and then with a hdri. all with only very simple diffuse materials.
Maxwell uses my quadcore 2,66 Ghz with 4 GB RAM, Octane used my 2 NVIDIA 8700m GT with a sum of 64 cores and 2 x 512 MB VRAM.

I must say, there seems to be almost no big visible difference in the quality of the results between Octane and Maxwell 2 after exactly the same render-times.

Seems to me, that Maxwell in Version 2 has more efficient algorhythms that compensate most of the lack of render power compared to the pure GPU-power Ocatane can use.

Have some of you made same observations or is it only with my setup that I cannot see a big advantage of Octane's renderspeed compared to maxwell V2 ?

it's a good question, we know for sure that octane is faster the first minutes, but after some hours of rendering it becomes hard to tell which one is more efficient to clean the remaining noise.

Here are my results:

All texture is simple diffuse material, no SSS (Maxwell) etc.

1) DayLight-System, 3 minutes rendering:

Maxwell:


Octane:



2) HDRI (same for both), 5 minutes rendering:

Maxwell:



Octane:




Can anyone see a big difference in the render-qualities ?

But btw., beside that Maxwell is surely much more evolved than currently Octane (I hardly miss SSS and displacement), the price-render-quality-relationsship is clearly on Octane's site.

I think difference would be better seen with at least GTX260 (with 216 cores) or even better with GTX 465/470/480.
For my configuration GTX 470 about 5 times faster than GTX 260 in octane.

Maybe Octane not so mature yet, but brute force with proper hardware (GTX 4xx, GPU Expanders, etc) give a real speed up compared to CPU renders.

p.s. It would be nice to create different thread for such tests to see the difference between Octane and other renders.

Hey,

you really can't make comparisons between them as they run on completely different architectures.
i think one should compare a modern CPU of the same price range as a modern GPU to do tests,
octane's speed depends entirely on your GPU speed, and a laptop with a 8700 is not very fast.

Why is the DOF off in the maxwell renders?!

Ah, ok its a 8700gt!

Keep in mind that octane actually uses pathtracing, maxwell uses MLT, we will see with 2.3 how octane performs with MLT.

Dunno if it has been reported, but reloading the same scene over and over will eat up all the ram. In my case it didn't take long to get Octane to use 8GB of ram.

hey,

this is a known issue we're working on.
i recommend launching a new octane render for every project you work on.
