Running Cycles on a 2080ti gives me this error: "CUDA binary kernel for this graphics card compute capability (7.5) not found."

After digging around and finding lazydodo's old post I learned that I would have to wait for new kernel rebuilds with the new CUDA 10 toolkit. Is there an idiot-proof guide to do this? I'd work on it if someone could point me the way.

If not, is there an ETA on when it'll be updated to support 2080/2080ti cards?

EDIT: It's possible now!

You have to get a newest 2.79 (aka Official) build from Blender Builder. It has CUDA support but the kernels are missing. That's easy to fix, however. Get a CUDA 10-based Linux build from GraphicAll. Then go to blender\2.79\scripts\addons\cycles\lib. Copy the filter_7*.cubin and kernel_sm_7*.cubin files to the corresponding folder in the Windows build. It should work now :)

Thanks to Carlo Andreacchio for showing this method in a comment on GraphicAll.

Original answer:

I tried to recompile Blender with CUDA 10.0. Sadly, the library that Blender uses for initializing CUDA (cuew) didn't even recognize the toolkit. Last commit is from 3 months ago, when CUDA 9.2 arrived. We have to wait...

  • $\begingroup$ @Amir Thanks for the link. I edited my answer, as an easy method appeared recently for people who can't build. $\endgroup$

  • $\begingroup$ Nice workaround, but keep in mind that this solution does not work since things in recent builds of Blender keep changing and copying the libraries from an older version of Blender might cause crashes. So the only reliable solution is to compile Blender from source. $\endgroup$
