I'm planning to buy octane for 3dsmax but as a vray user i'm thinking that you may have the same or even better / cleaner result with vray with a 90min render.
What do you think about performance / result ?
this is true but vray doesn't compute a lot of things that Octane does.
Vray isn't spectral, doesn't calculates exact diffractions, caustics, etc. Vray is totally biased.
To compare Vray speed to Octane you have to launch a render using Bruteforce for primary and secondary rays.
If in the scene you will get a lot of glossy or specular mats Vray will sit....Octane will continue slowly and you will be able to tweak well materials, lights and textures.
Vray-RT is not comparable to Octane rt feedback....and Vray-RT gpu often (2.03) crashes your system, you have to reboot.
Gpu rendering is a new technology and this year with the new Gtxs or Teslas we will get more ram and more power.
Cuda is evolving and Octane (perhaps) will use the cpu power too (iray-arion already do it).
You need 3 or 4 gpus (2xGTX590 or 4xGTX580) to achieve clean renders and cook your scene for 3-4 hours if it's a 3500x2500 pixel your final image.
Remember that if you create a 1920x1080 frame you need to render it a 3840x2160 pixels.
Then in Photoshop or AfterEffects you have to apply a denoise filter, downscale the image, add color correction....and you frame will be perfect!
