How do I lower the resolution and AA on Gear VR?

You can’t. It’s hardwired to run at full resolution on Gear VR.

I need to lower the resolution and maybe disable AA on a Gear VR project. It looks great but it’s overheating too fast and the framerate is bad. On 4.10 it was obviously a lower resolution, but it ran fine. I’ve adjusted the device profiles, but it seems that they are ignored when deployed to the Gear. Thanks in advance.

It didn’t in 4.10, but I think that was before the Oculus API was at 1.0.
