I noticed a framerate drop on my Quest 2 as well. When I exported the .apks for the Game Jam, I think I had the forward_plus rendering method on.
I have switched to gl_compatibility and it seems to be running a lot smoother. I was nervous to upload a new apk though since I made a couple other quality of life updates since the submission deadline. Once the voting is over, I will update the apks so that they are better for other devices.
Thanks for the feedback! This is the first VR game I've distributed to others to play, so I'm still learning a lot!
