Android 3d game hangs on startup for a few minutes with gles3 on godot 3.3.4 and later when a 3d object is present on screen.

Godot version

Issue description

On the motorola e7i power the game hangs on startup for a few minutes on the godot logo when glse3 is in use on a 3d project. this happens with both the debug and release version of a 3d project and it doesn't happen with other devices I've tried. The motorola e7i power uses PowerVR GE8322 as gpu. i downloaded GFXBench Benchmark from google play and it can load scenes without hanging. i could try other 3d games that use gles3, but i don't know any.

Steps to reproduce

1) create an empty project with gles3 and add a mesh/sprite3d and a camera. 2) export to android

Minimal reproduction project

gles3m.zip

Edit

I want to clarify that the game run after a few minutes. It's like if it gets stuck on something while loading.

What happens if you delete the default environment .tres file? (A common culprit in similar issues is sky radiance map generation)

[Calinou]

Using the GLES2 rendering backend is preferred over GLES3 on Android, as lots of devices have poor GLES3 support in practice (especially old/low-end devices).

[Nyre221]

@Zireael07 I tried to delete it and nothing has changed. even creating a new one and trying the different modes doesn't help. I also tried to change the quality/compression settings of the project and it still doesn't work.

@Calinou i know that gles3 on android is not supported very well, but in this case it seems like a problem with godot and not with the phone. besides that, glse3 supports things that are not possible with glse2 like the hdr i use for the glow effect and the shaders for the blur (the only way i found in glse2 is very heavy). Also, godot4 will not have only gles3 and vulkan? just to be sure, do you know any games made with another engine that uses gles3?

this time i searched for godot:

adb shell logcat | grep -i godot

tell me if there is a better way to see the logs.

[Calinou]

Also, godot4 will not have only gles3 and vulkan?

It will, but the GLES3 renderer in 4.x will use a more low-end friendly approach that plays better with Android GPU drivers. The GLES3 renderer in 3.x is high-end-oriented. It was never designed with the limitations of mobile hardware in mind, other than using GLES in the first place (instead of full OpenGL).

ah, I didn't know this. thanks for the info!

@Calinou @Zireael07 I want to clarify that the game run after a few minutes. It's like if it gets stuck on something while loading. I apologize for omitting this.

[Calinou]

@Nyre221 Can you reproduce this on Godot versions older than 3.3.4? The issue title implies this, but please comment to clarify this.

If so, this is likely a (very long) shader compilation stutter, so I'm not sure if anything can be done about it. Asynchronous shader compilation/ubershaders are a bad fit for low-end mobile devices, so they're not a viable solution here.

If I remember correctly this also happened with the 3.2 version of godot. Unfortunately I don't have a stable internet connection at the moment and I can't download anything to check.

[Nyre221]

@Calinou I recovered the 3.3.2 version of godot from an old disk and the problem is present there too.
