godot 3.1 alpha2 tilemap Low frame rate on android

[myhalibobo]

Operating system or device - Godot version:
Honor 8 Lite
godot 3.1 alpha2
I looked at other related ones and I didn't get a solution. This is a screenshot of me running on android,fps 46-49。


Link to minimal example project:

I'm seeing the same with 3.1 Beta 1. 180 of the same 64x64 tile brings the fps down to single figures on the two devices I tried it on.

Just to add on GLES3 I get 60 fps, on GLES2 I get less than 10fps

Duplicate of #24466?

[volzhs]

guess so

The OP predates the commit referenced in #24466 though IINM (alpha 2). But @usbhell's comment might be due to #24466 yes.

I see the same issue when rendering a lot of text on an older samsung kitkat device. I guess this is related to sprite rendering?

@underdoeg: Related to the fact every letter is a draw call.

[akien-mga]

Could you try again with 3.1 beta 2 (or 3.1 beta 3 which we'll publish tomorrow and might perform slightly better)?

[underdoeg]

performance of beta3 is about 10x better in my case. went from stuttering to smooth.

[akien-mga]

Thanks for testing. Let's close as it seems at least @usbhell and @underdoeg's reports were related to #24466 as @bojidar-bg mentioned. @myhalibobo's report predates that, but there were many changes since alpha 2 so performance might be better too.

If you can still reproduce the original issue on 3.1 beta 3 or later, it might be worth opening a new report to avoid the confusion with the alpha 4 - beta 1 performance drop.

@akien-mga I downloaded the test again, and my phone is still low framerate,It is 44 FPS,The phone model is hua honor 8 lite and godot 3.1 alpha4

[volzhs]

alpha 4?
we have a beta 3 now. should be with it.

[myhalibobo]

@volzhs yes,I didn't test bata3,I wrote it wrong. I tested bata4
