[Gear VR / Oculus Go] Any optimizations or Vulkan, or ES 3.1 support coming to UE 4.19 / 4.20 ?

ES 3.1 has always been supported! Daedalus is proof of that :)

ES3.1 is supported to the point where UE4 runs on Gear VR with ES3.1. However, it doesn't seem to be optimized at all and is deferred (ES2 is forward from what I've heard).

Here are some points from Oculus themselves:

I am aware those are from 2016, but as far as I know nothing changed in UE4 regarding ES3.1 and Gear VR.

Here is some information from our integrations team:
"On the mobile codepath, if you check in the ES3.1 box, you get the ES3.1 version of the mobile forward renderer. There is also the "ES3.1 mobile deferred" box which obviously is a deferred renderer that you shouldn't use."

The only option I see with "ES 3.1" in it is "Support Open GL ES3.1" as per https://docs.unrealengine.com/latest/INT/Platforms/Android/OpenGLES31MobileRenderer/index.html

I see there is "Support Open GL ES deferred shading", but I never checked that box and I still get horrible performance when "Support Open GL ES3.1" is enabled. So I am not sure whether that box is related to ES2.0 or ES 3.1 is simply that bad in UE4 when it comes to mobile VR.

Is Unity optimized for ES 3.1 or Vulkan on GearVR?

Yes on ES 3.1, no on Vulkan

This is the link from Intel to install Vulkan to UE4.19

I don't see how it relates to Oculus Go / Gear VR.. It's more about PC and Intel hardware.

@imperativity

I just saw in https://developer.oculus.com/blog/august-monthly-tech-updates-/ the following:

"Mobile SDK: The 1.16 release now exposes experimental Vulkan support for the Oculus Go..."

However no Vulkan is mentioned in UE4 Integration notes.

Do you happen to have info about when Vulkan for Go will make it into UE4 ?

Thanks beforehand

@imperativity

is there some update on using Vulkan with UE4 on the Oculus Go?
