Framerate much lower in packaged build on Oculus for TextureRenderTarget2D for spectator camera
This issue have been reported as UE-70352. https://issues.unrealengine.com/issue/UE-70352
Below is a description to reproduce the error as the description on issue tracker is incomplete.
I tried to implement a spectator for my app by using TextureRenderTarget2D and discovered a weird bug. Everything works fine in the editor, BUT as soon as I package my project the frame rate drops really low (<15fps, sometimes less than 5 fps).
This is a bug related to Oculus somehow, because when I try running the packaged project with my HTC Vive everything works as expected.
Steps to reproduce:
The frame rate will be fine inside the editor. But the frame rate for the packaged project will be very low. It becomes very visible when turning the head from side to side.
The bug have been present since version 4.19 (at least) and is still present in the 4.22 preview version.
