Performance issues after building APK for Meta Quest 3

Hi everyone. I'm new to VR development and just created my first VR project in Unity for Meta Quest 3. When I run the game through Unity Link (Oculus Link) from my PC, it works smoothly with good graphics and no lag. My PC has 32 GB RAM and the game uses around 9 GB while running. But when I build it as an APK and run it directly on the Quest 3, I get problems like lagging, lower graphic quality, flickering, and sometimes low memory warnings. I know Quest 3 has only 8 GB RAM, so that might be part of it. But I would really appreciate help on how to optimize the game for Quest 3, what settings or methods I should use to reduce lag and improve quality, and whether there are tools to check what is using up memory on the Quest. Thanks a lot. I'm learning and want to get better at building for VR.

    Hello there!

    There's many ways to optimize your project, something that may help you decide where to start is the Meta Quest Runtime Optimizer. This is a tool still in its experimental phase, but its intention is to help developers find and resolve performance bottlenecks in Meta Quest applications. I will also link you to our documentation on testing and performance analysis. On the left hand side of this second link you can also find more specific documents on optimizing certain aspects of your project.
