    I was looking forwards to the latest features of 2020 for my next project, where I'm currently using 2019. However, load times are insane! I tried a basic URP project with new Input Method package and the input test scene, and it takes a minute from pressing the icon in Android to the scene showing. A plain scene of 1 capsule and 1 directional light took just as long. So then I try a standard renderer project with nothing but a capsule and a light source, and it still takes 45 seconds to display anything.

    A clean 2019 project with a capsule and one directional light is running in under 3 seconds! This is on an LG G3 running Android 5. I haven't tested other devices yet.

    Hi @SoftwareGeezers,

    Would you mind checking what's happening during this time, using Unity's Profiler?

    In any case, if a very simple project as the one that you're mentioning is taking so long, it seems to be a bug worth checking.

    Would you mind also to report it, following these instructions: https://unity3d.com/unity/qa/bug-reporting ?


    Thank you!

    Just ran a blank project with a scene one light, one cube, one capsule. 30+ seconds on the LG G3. 11 Seconds on an nVidia Shield. Here's the LG G3 profile:

    By comparison here's the same thing taking 3s to start when created on 2019:

    Edit: I saved the profile data if that'll be any use.
