GearVR works fine with ES2. I could not get ES 3.1 working on the GearVR(compiled from 4.10.1 source), the app simply closed(didn’t check the log). But it was just for a test anyway. Currently all major GearVR games with UE4 or Unity use ES2(Gunjack, Anshar Wars, Land’s end). ES 3.1 is only suitable if you want to use the deferred rendering path, wich i assume is a bit too heavy for the GearVR.

However, Oculus and Unity recommend using GL ES 3.1 and forward rendering, even though Unity also can use GL ES 2.x. I also recall ASTC compression is only usable with GL ES 3.1 render target and capable hardware, which is what S6 and alike provide.
