We don't have a demo version for kepler at this stage but there is a test build of the commercial version that runs on kepler (most of the 600 series).
The reason for this is that we have not been able to get satisfactory performance out of the 600 series. The architecture is considerably different from the 500 series (fermi) cards and therefore the higher number of cuda cores does not directly translate to higher performance in OctaneRender.
Currently a 680 performs about 60-70% as fast as a 580 in OctaneRender.
In short: The official commercial release does not support Kepler, however there is a test build for licensed customers that does.
Thanks for the great info! So, most 600s work in that build for the commercial version... but at this point they don't work very well. At least not as well as "lesser" cards. Am I understanding that right?
Most of the other 600 cards are actually still fermi cores so they should run ok on the standard commercial release.
(To the best of my knowledge these are the 605,610,620, some 630's,640 and 645).
.... a GPU ray tracer (iray, VRay-RT, Octane, etc.) must fit the scene entirely on each GPU. The more memory on the GPU the larger the scene you can render with GPU speed. Renderers based on NVIDIA OptiX can support paging to system RAM, but there aren’t any of these publically available for Max yet. Be careful when examining specifications for dual GPU cards like the GTX 590 or 690 as they might be marketed with their combined memory total rather than the per-GPU memory that is available for ray tracing......
We’re still optimizing iray for optimal Kepler performance here at NVIDIA, so it’s not Autodesk dragging their feet here. Our team is working hard to get out something you will like this summer. But to set expectations, you should not expect the initial Kepler products (out now) to deliver a dramatic speed increase for iray over their Fermi generation predecessors. While Kepler has many more cores than Fermi, they run at much lower power, which means they have less performance per core. The gain you are guaranteed to see is superior performance per watt. This also makes it much easier to fit larger or more GPUs into power-constrained systems.
As for viewport/raster performance, it’s quite possible that many high end GPUs will not report high usage unless your scene is really taxing the GPU, most likely with many programmable shaders. High face counts and texture usage impact memory far more than they do workload. The graphics pipeline itself can also have a bottleneck. Here NVIDIA is working with Autodesk (and many other companies) to eliminate unnecessary data transfers that hold back the GPU. This not a reflection on Autodesk’s ability to design but rather how much more rapidly GPUs have evolved than CPUs, as these practices were often negligible to performance a GPU generation or two ago. The good news is that once these “speed bumps” get removed, all modern GPUs should benefit.....
I have a little gamer station, used for hard works, ASUS G55VW, with Geforce GTX 660M, latest nvidia driver, and i7 3610 QM. Its very fast.
- The demo version dont work, (little "failed" and clear window) - i updated drivers - dont work
- If i buy the Beta version, it will work on this machine?
- I work also with Softimage, what is yout opinion, when will be avaible this softimage version?
- If a buy Beta, can I change licence later to octane for softimage?
I work, for long time (10+) as professional, and I want to test your engine, and searching for painless solution. Other little question: Octane deals with motion blur too?
hi Rafael,
the OctaneRender demo is based on beta 2.57 which is built against fermi generation cards. The current commercial beta 2.58 is also still using the 5xx cards but we aim to optimize Octane eventually for the keplers. So as of this moment, the commercial beta 2.58 will not run on your machine. There is a version for kepler but it will not yield the same performance as the one for the fermi.
As for the xsi plugin, an integrated plugin is still being developed. Licenses cannot be transposed, so if you buy standalone edition license this cannot be exchanged to a plugin license later on. Besides this, the plugins actually need to run on a machine that also has an authenticated standalone edition installed...
