Same thing happened for me. Installed 418.81 this morning and it broke Octane 4.02.1 R3. Removed 418.81 and installed cudadriver 410.130_macos and all is working again.

( apologies, posted this in wrong thread )

Hey all,

I am having a similar issue, getting this message :

OctaneRender 3.08.4 (3080400)

CUDA error 999 on device 0: unknown error

device 0: failed to compile module 0

However, i tried your advice and downloaded and installed the driver version, however i could not successfully complete the installation becuase it said " this driver is not compatible with your version of windows".

I am on Win7 64bit.

I am currently running Octane version 3 ( latest version ) and i have a GTX 1080 ( strix ROG ).

Any suggestions and/or help would be so deeply appreciated.

Thanks all,

Adam
