I made an apk in Unreal Engine 5.4.4. Without any changes to quest 2 or quest 3 they both are laggy. But if I change Quest 2 in Sidequest to use cpu/gpu level 4 and set the refresh rate to 60 Hz the Quest 2 won't display the lag. Quest 2 runs great.
I can't do the same on Quest 3. 60 Hz will not display correctly (graphical errors). Turning it up to 120 Hz looks the best but still shows a lot of ghosting. Anything other than 120Hz displays as lag.
This is a multiplayer game but even running as a single player it still shows lag. Just moving the VR hands around is laggy.
I have tried changing my code (at first I thought my code did this but now I'm not sure about that) and changing just about all settings in Unreal Engine Edit Project settings/rendering and nothing fixed it. I changed pixel density to 1 and the Quest 2 liked that. Without PD 1 it's laggy. I tried rebooting the Quest 3. I tried factory reset on Quest 3. Still nothing changed. I'm using both multi-view and instanced stereo even though every guide I've read says only to use one or the other but it will only render ONE lens if I don't use both. I also changed the CPU/CPU to sustained high and tried variations with one low one high, both high, etc... NOTHING changed.
It wasn't doing this before the recent updates a few weeks/month ago.
Any ideas why it's acting this way? Was it the update? Anyone else have this issue?
Solved! Go to Solution.

Fixed:
I unchecked smoothing and set the minimum framerate to 90.
I'm also going to try the other settings here (which is where I found out to disable smoothing and set the minimum framerate: https://stackoverflow.com/questions/59438497/unreal-vr-build-is-running-only-at-60-fps-why-but-runs-...

Update: I found that using Quest 3 in editor works fine (run in VR) but after compiling and uploading apk to meta store and then installing on the Quest 3 headset it has a different resolution and is laggy. It looks fine in Unreal Editor but I still don't know why.

Here's my Project Settings/Rendering settings:
Let me know if I need to show any other settings. Thanks
