UE4 + Quest : FPS drop when running a release version of the app for the second time

The first time a shipping version of the app is launched, everything runs fine and we're hitting 72fps on the Oculus Quest. However, immediately after a restart of the app, there's always a consistent drop in framerate (~10fps lost)

This seems to happen only when we create a release version for distribution, and not when we build a regular shipping build. 

Has anyone else noticed this happening ? 

FYI we're running the Oculus branch of Unreal Engine 4.22.1

    Same thing happening for me on a Unity build. Did you find the culprit?

    • does this also happen to you when you just deploy it to the Quest?
    • is it actually checked by default "create a release verison...", or did you manually add it?
