>> I am not clear why they are having performance issues but the NVIDIA Shield I have, based around the same or even earlier version chipset, is capable of outputing 4k games to my TV at quite excellent frame rates.

Could it have anything to do with Zelda's engine?

When Street Fighter V moved to the Unreal Engine, it used way more resources than its predecessor even though it didn't really look that much better.

I went from being able to play Street Fighter IV in 4K/60fps at max settings to 1080p/60fps at slightly less than max settings for Street Fighter V on my laptop with a GeForce 860M.

While I don't have hard facts, I suspect the engine change might have had a lot to do with the lower performance.
