Both of these rendering technologies have significant benefits in terms of quality and efficiency. I tried my gpus as Optix devices and rendered ok with no difference in rendertime, say one given image 3 minutes And now that we can use Gtx gpu as Optix devices, what if I buy one Rtx 2060Super and try to render as Optix devices Gtx + Gtx + Rtx? Aug 5, 2019 · The problem seems to be the type of BVH, Optix uses an specific BVH system, Optix BVH, while with CUDA we have to use BVH2 and with CPU alone we can use BVH2, BVH4 or even BVH8. opened 2019-10-19 04:29:58 +02:00 by Eric Klein · 18 comments Eric Klein commented 2019-10-19 04:29:58 +02:00.

I always thought when CPU + GPU is activated, Cycles would utilize the strengths of the CPU and the GPU to distribute rendering across both. When Optix was first created, this was a matter of specialized software tools that were able to generate highly optimized machine code for ray tracing and associated tasks. Eurika -- evidence If I uncheck Persistent For that you need to edit CYCLES_CUDA_BINARIES_ARCH in the CMake configuration, and leave only the architecture needed for your GPU. However you options are more limited when compared to older versions of Blender. Mathieu promised to contribute e-cycles improvements after a year, but that year has not passed yet. What is OptiX?

The motion vector directions from the OptiX temporal denoising sample seem to line up with what Blender/Cycles expect so I believe Cycles motion vectors should work with OptiX. Stay up-to-date with the new features in the latest Blender It’s clear that when you compare the two parts together it seems logical that you don’t see your cpu slowing down your gpu 😂 I was more thinking of a reasonable price top of the line cpu then like the 2950x or 1950x. Doesn't matter if it's CUDA or OptiX, same outcome. Follow Hi, I’m very content with the addition of NVIDIA OptiX to Cycles, my thanks to the devs. New Issue. 3. The scene I THINK is a bit complex (I'm a newbie, so I may have not optimized it properly, but it's nothing CRAZY complex), but it seems that non-optix, just CUDA rendering works. Stay up-to-date with the new features in the latest Blender releases. NVIDIA CUDA vs. Further investigation revealed, that - unlike CUDA - OptiX support requires a wor A simple readme stating the intent of these files might be enough, though. So far optix is a bit faster than cuda, I guess that will be improved over time. What happens is the ray hits the "back side of the cube", Also, I took a look at things and my suggestion from previous comments (Cycles may be using the “wrong” motion vector format) is probably incorrect. Download. 81 which is faster than Cuda . Running with 2x NVIDIA `#4` on Debian 9 with NVIDIA drivers `440. exe /c "SET CYCLES_OPTIX_TEST=1 && START /D ^"C:\dev\Blender\Blender Portable^" blender.
