When will all core 22 projects use Cuda?

It seems to be a huge hit and miss. One day 20mill PPD next day 15mill PPD. Seems like allot of projects still not using Cuda.

No AMD GPU will ever use CUDA, if Intel ever makes a GPU F@H uses, it also won't use CUDA.
Nvidia GPUs older than Kepler cannot use CUDA in F@H.

So far, all Core_22 WUs seem to use CUDA, if the above is true.

Believe the current 22 core will check/use cuda if applicable projects running 21 core wont ... one thing to note is that as I understand it WUs are baselined on OpenCL - cuda boost helps different projects to different amounts so when using cuda there will be some variance and with QRB this might be quite significant

Moreover, if you have Nvidia GPU that is Kepler or newer, if there's a CUDA issue, it will fall back to OpenCL. Eventually, we hope to resolve all issues and errors (within reason) so that virtually all Nvidia GPUs can run CUDA without using the fallback to OpenCL
