Want to use Vulkan but Mupen64 doesn't support it? So, I'm on a Shield TV.  Using gl driver, I can use Mupen64 and I get perfect performance.  However, other cores seem to benefit from Vulkan.  In fact, it seems to be preferred for performance overall.  Yet, the only N64 core that seems to support it is Parallel and it has frighteningly low performance.

So, am I just out of luck?  Are there settings for Parallel that are not default which would bring performance in line?  Can I override video driver per core somehow so that I can use gl just for Mupen64?

Thanks!
