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 Quest build settings for Arm64+ES3.11.3KViews2likes2CommentsCan't get console to show up in the project running on Go. Is it even possible?
Back in my Gear VR days, I would always use bluetooth keyboard to pull console down and do "stat startfile" to better understand the bottlenecks (or where new version of UE4 has issues). Tried doing the same last night with my UE4 project on Go and I couldn't :( UE 4.22 p3 performance is a way worse than 4.21.2 on Go and I fail to figure out why (and Epic doesn't care to look at my project - they always want free QA done by devs) I paired my bluetooth keyboard to Go and it seems to be working fine (at least Esc key works). However, pressing a key that is bound to console does nothing. Therefore I can't do "stat startfile" (or any stat cmds for that matter) :( Has another had such issue (console not working) ?

I was learning / working with particles for my project and it turned out that GPU particles are horribly slow (and probably bugged/broken) in Gear VR. Here is the video with CPU particles (performance drops are due to video recording): https://www.youtube.com/watch?v=6ZjtqHaKSlg Once the drone crashes and particle system attached to it is deactivated, fps is still good. When I made smoke trail on the drone flying over in the arc to be GPU particles (exact same look and rate), fps dropped to the floor and even after particle system got deactivated and visibility was turned off, fps still stayed super low. My guess is it's a question to Epic, but I am sharing my finding here too.3.3KViews0likes13Comments
