Modified drivers with full OpenGL support? topic

I am vaguely interested in a nexus 9, but the driver gimping is a non starter. I do play some Tegra optimized games, and frankly I refuse to give them up because of Google handiwork. I was considering this device as an alternative to the shield tablet, but if this issue can't be fixed I'm going to stick with nvidia's offering. FYI I do already own the shield tablet, I was just considering a switch due to issues I've been having.
