# RTX support for Cycles

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.
