Bug (Case 1346761) Error SwappyVk: Failed to wait for fence 2

When running android build at Mi Note 2 phone, I get super slow fps like 10+ only and the android logcat keep spamming Error SwappyVk: Failed to wait for fence 2.

 

@JussiKnuuttila Any new update for this issue? Zero update since 29 Jun. Can u help me get Vulkan team look at this issue as it most likely caused by Vulkan related bug. I also updated multiple phone testing results at this case.

 

@joelv Ya. Case 1346761. I ady put case number at thread title long time ago. Btw I also get a reply from other thread mentions that it's very likely related to this issue. If it's the same issue and can't backport to 2020 LTS, will Entities package compatibility moves to 2021.2.x as soon as possible along with Hybrid Renderer package? With this issue I will not able to ship my title.

 

Hi @joelv @JussiKnuuttila Just let u know the bug has been successfully reproduced by QA. https://issuetracker.unity3d.com/is...kan-error-swappyvk-failed-to-wait-for-fence-2

 

@JussiKnuuttila Which Unity 2020.3 LTS version will fix this issue?

 

@joelv Actually is that Hybrid Renderer specific bug or Vulkan bug?

 

Hi @joelv. Seems like next version of Hybrid Renderer will move to Unity 2021.2. Can u check whether the bug is still reproducible?

 

@joelv Alright now no more error spamming but the frame rate still very low like before. I guess now it's hybrid renderer performance issue since the same scene perform so much better at regular game object scene.

 

Also getting this with a game crash, at a very specific position in the level, looking at something that may cause it.

Code (CSharp):

1. 2022.05.24 17:19:46.133 25269 25493 Error SwappyVk Failed to wait for fence 2

Info:
Device: Redmi Note 9 Pro
Unity Version: 2021.3.3f1 LTS
Note: My framrate is very good! Remaining at max 59-60 fps as it is capped there. I realized this performance jump some unity sub versions ago. Good job on that!

Test:
As @joelv the test with
"Optimized Frame Pacing" off.

Resulted in a more detailed error message:

Facing Same problem, Any updates regarding it? @joelv .
only appears with Android Builds as slow lagging frames before screen blackens and stop or crash. I started to get this issue only after I upgraded from 2020.3.9 to 2020.3.11f in order to use VFX graph in my game. What am I doing wrong? Any suggestions? Any workarounds?
using:
Unity 2021.3.11f

What did you do to solve this issue? Did you find any workaround?

 

I never did. I am working on another project now.

 

This is still a major issue for me. Any news on this error?
