Question by KEric · Apr 18, 2017 at 03:28 PM · unity 5bugmemoryresourcesbug-perhaps

Scene loading time after upgrade from 5.5 to 5.6

Has anyone noticed or know the source of an issue with the loading time of a scene in Unity version 5.6? After upgrading from 5.5 to 5.6 loading a new scene significantly takes a longer time. Anyone?

I also experience much longer scene loading times in 5.6 compared to 5.5, 5.4 and 5.3. In my case it happens when building for android and loading a somewhat big prefab using Resources.Load() at the start of the scene. In that case the culprit seems to be the Resources.Load call. On device the loading of the prefab (not necessarily at the beginning of a scene) takes up to 15x longer in 5.6 than in previous versions. Something must have changed in this area. I've done some profiling about the issue so if you are in that case I can tell you a bit more. I've sent a bug report about this issue. No answer for the moment.

Thanks for pointing the issue out and filing the bug report. In my case I've just downgraded back to 5.5. If there will be a fix, please post the information about it and I'll close the issue. Cheers

The QA were able to reproduce the bug. I'll post here when I learn more about its fixing. And for the moment... back to 5.5.

There is a new version 5.6.1, do you know if it has been fixed?

This bug has not been fixed yet. You can follow it in the issue tracker (case number 904652). Also browsing the issue tracker, you'll see that there are quite a few active issues related to resources loading on Android. Not sure this fix will solve your problem.

This happened after Unity's upgrade from 5.5 to 5.6, so your point is completely invalid

I have the same problem after upgrade my Unity from 5.4.2f2 to 5_5.6.1F1 and it's the same in 5.6.2F1 Does anyone know why?

It happends only in old devices like Samsung galaxy S3/S4, Galaxy tab 3, and so on, but for example in my galaxy S6 loads fast.

Thanks,
