Just an update (good news)! The Nvidia shield update 5.0 fixes dolphins vulkan problems. All my games are working with the new update and vulkan. Also, they seemed to have updated opengl as well, they are at least using opengl 3.1, possibly even a newer version than that. Lastly, it is running android 7.0 nougat, and I like the new layout. The controllers got a nice update as well, although I'm not a fan of the nvidia games app, the hub was better in my opinion.
Edit: more bad news, gamestream is broken I cant even start streaming games, then again its always buggy, so that's not news.
