Latest Unity Patch 5.2.1p2 is super slow on android tablet (Galaxy Tab)

My game compiled with Unity Pro 5.1.3 for Android runs with 50FPS in the initial screen. It works fine. I attach the profiler capture. "Capture5.1". This is with graphics set to compressed.



When I updated to 5.2.1p2 with all the same settings and graphics to compressed and normal compression the speed difference is frightening. Its supper slow, only 18FPS in the initial screen. I attach the profiler capture. "Capture5.2". All of it is Camera.Renderer and then gfx.waitforprefex.


As you can imagine I downgraded again. Second time, I have done it again in 5.2.0.
Any solutions please?

 

Also the graphics in 5.2 and compressed:normal looks worse than compressed in 5.1.

 

Any help appreciated...

 

I have Galaxy Tab A too, and our game performance dropped from 60->30-40 fps when upgrading from 5.1 to 5.2. It's something about the textures/images/sprites on the scene.

 

But we need an official answer about this. I am a Pro customer and I cannot use the latest version.

 

Same here. Any answer from unity team would be great.

 

Performance issues on Android have been reported throughtout thread, it seems issues still present on latest builds.
I have not seen any official replies except post bug reports. Thing is no patch release ever says anything about performance, really each release getting worse which is super sad. I just hope we can get a patch release that stabalise this as Unity is moving to fast feature wise, but little performance on mobile

 

I hope what they did for android from 5.1 to 5.2 they will take it back since it brought disaster in performance.

 

If you don't report your bug they can't fix it because they won't know!!

 

I have already reported them with no reply.

 

In that case post your case number here and anyone from unity that comes across this can see the case number and chase it, it's likely QA are still testing to get a clear repro on one of there devices.

 

Also as a pro user you could test and see if 5.3 causes the same issue and if so post it in the pro forum, I know Alex is quite on the ball there with getting stuff looked at.

 

Bug Case 732882
I would try unity 5.3 but it needs to much time to install convert project and try, then delete and reinstall the backups and old unity. I have also my work to do. Anyway I hope I get an answer saying that this is the cause of this delay and this is the way to make this as fast as before.

 

If anyone else tries 5.3 and it runs as fast as 5.1 in android please tell me, then I will try it too.

 

Might have found a fix, check all your UI Sprites or Images, and if they don't have a material:

- Add material with shader: Sprites/Default
(if image doesn't need transparency, use Mobile/Unlit)

I have a background scene compiled with several UI sprites, none had a material. After adding a default material to every sprite, performance was back to 60 fps.

 

This sounds promising... Does anyone else fixed it like that?

 

Still no luck. Downloaded the latest 5.2 patch and tried the above solution but nothing at all changed. Still the same performance. I also noticed that static batching is not working, even after I disabled dynamic batching.

 

I am downgrading again.... I also noticed that unity has a 5.1.4 (released 6 oct) version now. This tells me something that they know about the problem and its hard to fix.

 

I also noticed that UI is not causing the delay. Even after I disabled all the UI I still go 15FPS when I got 60FPS with the 5.1 version. This is really strange...

 

5.1.4 works as expected. 60FPS. I am not updating again!!

 

Thanks for posting this, looks like I'm downgrading to 5.1.4 as well, as I've had an insane drop in FPS on android.

 

Also I use Texture PackerGUI for the sprite sheets. With the new compression settings in Unity 5.2 what is the right option for compressed graphics PNGs from Texture PackerGUI? Compress Texture PackerGUI with RGBA4444 with FloydSteinbergAlpha dithering and then in Unity Compressed with best quality or normal? The quality looks worse than 5.1.

 

Or use Texture PackerGUI with RBGA8888 PNGs and then Unity Compressed with best quality? Or PKM with ETC1 right from Texture PackerGUI? I am confused with this...

 

Thanks! I've changed all my UI Image materials to Sprites-Default (expect the ones were I use a scrollrect because that needs stencil stuff). And now it running almost as fast as the same project in Unity 4.6.8. Just +/- 5 fps less

 

Why doesnt this work for me?

 

I cannot attach my project, its 2gb. What was the default choice in 5.1.4 and how can I change back to this?

 

My tablet is GT-P5110 with 4.2.2

 

Maybe a blog posting/stickies on this change may help in the future, not sure if everyone is understanding the change as of course people do not read much these days (change logs)

 

We have unity pro 5.2.1p3 and the same performance issue on galaxy Tab 4 ... You can see 2 different pictures before and after deleting ONE image component in our main canvas.

Performance has improved by 10 ms !

We need to release our game next week and can't get a decent performance on a simple GUI while 3D scenes are running well.

Also adding material with a custom shader to image components has improved performance by 30ms. Related to the post :

So you believe that if I change the setting in build setting in android of the texture compression from 'dont override' to ETC1 or RGBA16 it will work like before?

 

As I recall there was a global override menu in build settings in 5.2. you mean that there is no choice 'ETC1 or RGBA16' and now its only a choice of Etc1?

 

Maybe the tick box for 'compress using ETC1' in textures works only if you use the build in Sprite packer for atlases, but some of us use Texture Packer to make the atlases, maybe this tick box does nothing for those atlases.

 

I suspect that most of the issues will go away if I use the build in Sprite Packer instead of Texture Packer. I will test this on the next 5.2 release. Are any of you having performance issues on Android use Sprite Packer or another external tool?

 

Do you use Sprite Packer or an external tool?

 

Do you use Sprite Packer or an external tool?

 

Please help me guys to try and figure out where the problem is with 5.2. Are you all using Sprite Packer with the option compressed to normal? Or an external tool like me which is the popular Texture Packer.

 

We don't use Sprite Packer or an external tool :/ We have always the same performance issue.

 

So you dont use sprite atlases?

 

So if I change every texture with the tickbox ETC1 you believe I will have the old performance like in 5.1? Now I cannot test it, that is why I am asking.

 

I noticed a new version today 5.2.2 with this fix: (none) - 2D: Exposed alpha texture api for atlases compressed with ETC1. Has anyone tried it?

 

I downloaded the latest build 5.2.2 and still I get the same poor performance.
As you said I noticed that performance is the same with uncompressed graphics and compressed, no change.
This is because of what you say above. Compressed graphics with ETC1 on, off, nothing works, I have tried every combination. I even used Sprite Packer.

MY QUESTION:
Is there a way in the latest Unity 5.2 to use compressed graphics with apha RGBA4444 (like used in 5.1) in the older devices with no ETC2 support?
If yes how?
If no, you dropped support for older devices with ETC1?

 

I give up, I tried everything. I even tried IL2CPP android, which has the same performance but its twice bigger the APK. I am downgrading to 5.1.4 again for the 4th time! At least update to 5.1.5 to get the latest bug fixes.

 

Try 5.3 latest beta?

 

Dİd you test your game with other android devices?

 

I dont have time to install another one. I need to work too!! Maybe later.

 

No, but I'm sure it will work better on new devices. But the issue is to support the older devices too...

 

You dont need to uninstall unity 5.1 to try 5.3. You can have multiple version.
