I'm using 0.26 on 2.82a with RTX GPUs. When using Optix for Cycles rendering directly in Blender I get a performance boost of about 35-40% over straight CUDA.

With the CR add-on I don't see an option for Optix. If my Blender instances are set to Optix in the system settings, will it use Optix when I choose CUDA in the CR settings, or does that override the app settings and use CUDA? Either way, it would be nice to have the option displayed so that I know I'm rendering with Optix and not the slower CUDA setting.
