Hello guys,
I'm going to buy a new graphic card to use with octane because mine is a old 9400GT. I need fast previews and fast renders too (my final renders have to be 5000px wide), I will buy a new GPU, and I'm considering to buy a GTX590, but I'd like to know if Octane will be able to use the 1024 cuda cores it has, or if I have a better choice.
Sorry for my bad english.
Best video card for Octane

Hi, I'm in the same position as the OP above - I've found that the GTX 560 is sold in a 2GB ram version too (gainward et al), for around half the price of a single 3GB GTX 580 (palit or gainward), two 560's, according to my 'calculations' should be around 1/3rd faster than a single 3GB 580.. as long as scenes are under 2gb.
It's such a shame the 590 doesn't come with 2x3GB onboard, that really would be the ideal solution here.. Lurking the forums for a while now most people seem to think that the 1.5 GB limitation is an important one.
If NVIDIA's GPU roadmap to 2013 is realised.. wow.

How does the Octane manages the memory? I would be able to use only 1,5 GB if I buy the GTX 590?
Here in america I can find only the GTX 580 1,50 Gb nobody sells the Gainward GTX 580 Phantom 3GB here.
How is the memory usage if i have 2x GTX 480 for example? I would have only 1,5Gb avaliable?
Sorry for too many questions, but I'm a dumb in GPU's.

From what I understand the scene needs to be loaded into all graphics cards that are running, as the latency moving from mainboard ram to vram is too great - this means that the lowest active GPU memory size determines the maximum scene you can render, which means for the 590 will only be able to cope with scenes that are <1500MB..
The way I would look at it is like this - perhaps don't base your decision entirely around octane render and what it can support - octane is just one solution to the problem of unbiased rendering, I think the eventual winner will be a hybrid GPU CPU affair (but not in the VERY limited sense that arion is), with the tasks that each respective chipset excells at (linear or parallel) handed to the appropriate processors, there are a whole plethora of GPU engines that are being developed at the moment, of which Octane, to me, currently looks the most convincing - the moment Chaosgroup ups the quality of VrayRT so that it can be used for production rendering or indeed adds gpu/cpu hybrid rendering for biased (IR map/Light Cache/photon map) it's probably game over for a lot of these emerging stand alone render packages, given Chaosgroup already has a huge VIZ market share.. This is very much like the dawning era of GI systems for production rendering was, no one can really predict which software system will end up winning.. My personal hope is that new guys like Octane etc manage to hold their own, to keep the market competitive..
I'm going for 580 3GB, whatever system you use, Cude or OpenCL will benefit enormously from adequate vram..

That is correct. I would add one more caveat - video memory is also used by your computer for display purposes, as well as any applications that use video memory for the UI (via OpenCL or OpenGL). For example, if you are using a 3D modeling app that uses OpenGL, it will eat up memory from your video card as well. So if you want Octane to have the maximum amount of memory, then you should shut down any other apps that will use video memory.p3d wrote:From what I understand the scene needs to be loaded into all graphics cards that are running, as the latency moving from mainboard ram to vram is too great - this means that the lowest active GPU memory size determines the maximum scene you can render, which means for the 590 will only be able to cope with scenes that are <1500MB.
Or you can get a cheap second card for the display. I do that and my GTX460 is plenty fast with no memory or display problems, at least yet anyway.GeoPappas wrote: That is correct.
