I’m having an issue with planar reflections in 4.19 on the Oculus HMD.
I had been developing in 4.18. I migrated onto 4.19 due to a bug in 4.18 that prevented reflection captures from loading in a packaged game with streaming levels. That bug was fixed, but 4.19 has tanked my performance. It is a small arch viz project, so I am being somewhat aggressive with the visuals - but the performance was more than acceptable in 4.18.
After some trial and error, it seems to be the planar reflections that are causing the issue. In the editor viewport, the level runs at over 100 FPS, but when I test (or package the game) through the HMD, FPS drops to single digits if a reflection plane is anywhere in view (even if I set Max View Distance Override to very low).
So - is this a known issue? It seems to be specific to running through the HMD. My project is identical to the version I have in 4.18 - which was running fine.
Any ideas? (other than disabling planar reflections? They really help sell the scene).
