Installed a 3080 yesterday. As far as I know, the latest RH7 Beta is supposed to bring Ampere/RTX3000 support. Cuda rendering works fine but when I activate Optix, Rhino crashes when I start raytraced display mode. When I switched to raytraced the first time, Rhino went unresponsive. I guess some compiling was ongoing? I was impatient and killed the process, so maybe I just broke something? At least that’s the case when killing Rhino while OpenCL kernels are being compiled.
I would assume that the McNeel developers have gotten Ampere cards from Nvidia early and had time to test it?
I haven’t tried any of the available denoiser plugins yet. Will try that next.
I have the Asus 3080 TUF OC, it’s huge and heavy, although this model is still slightly more compact compared to most other models. Regarding the 10GB of Vram, this is enough for me. I don’t render big architectural scenes nor do I use huge textures. Mostly product renders and even 8GB of Vram have always been more than enough for my kind of work. For those of you who do architectural stuff, the 24GB 3090 might be more suited. But beware, Nvidia will bring a 3080Ti with 20GB soon, which will probably make the 3090 look like a pretty bad deal.
I’ll post further experience with this card here and hope others throw in theirs here as well.
Yes, it compiles the final kernel from the provided .ptx file. I’m actually not sure where the result gets saved.
Anyway, I’ll have to ask @jeff to test on the Ampere machine he has access to. Maybe I have to create a new .ptx file with the latest CUDA toolkit. I don’t know yet.
Bad assumption… NVidia hasn’t sent us any Ampere cards. Apparently they’re hard to come by, even for NVidia. It’s somewhat surprising that you were able to get one…and even more surprising that you got two.
I’ve been given access to a VM where minimal testing can be done…however, I did not test Optix…I will later today and see how it goes.
I should point out though…that the standalone renderer seems to take around 1-2 minutes of pre-processing before you see any kind of feedback in the command line, and before the render UI displays…but eventually it does start…
Note: This happens every time, so it’s not some kind of “initial” setup or compilation…
Note2: Switching in and out of Raytraced mode in the viewport, the rendering begins almost instantly, so I’m not sure what the standalone renderer is doing, but it does “appear” to hang Rhino…but eventually things start working and responding.
I was waiting for a new beta to fix my crashes with optix. no new beta release this week? or is there something else that I can try to make optix work with my 3080? I did send the crash reports.
