Why the game screen is basically static but the freeze is serious

My game is stable at 60 frames most of the time, but there will be a freeze for nearly one second every 4-5 seconds. The real machine debugging found the following situation.



I think my GPU is not stressed, it seems that the CPU is not processing any tasks, nor is there a large amount of memory recovery and allocation problems,but CPU is overburdened.So what caused the WaitForTargetFPS to appear?How can I avoid this from happening?

 

Nothing you're seeing in that view of the profiler is showing the GPU. That's all CPU. "Rendering" is the CPU rendering thread. Just further details on the specifics of the "Rendering" already shown in the CPU Usage chart.

In the top left click on "Profiler Modules" and select "GPU". That'll give you actual GPU timing info.

 

Thank you, is this it?

 

The sample frame correspondingly shows a static interface, and no other business logic is running. Can't understand why this is the case? Already turn off VSync from the Quality Settings in the editor.And it runs on Switch.

You have a problem on your scripts
Check that which script has a process every 4-5 seconds

 

I have checked it and haven't found it yet. By the way, what is your reason for making this judgment?

 

You must upload a full profiler cpu screen shot
your screen shot was for player loop only

 

It seems that there are really no tools for testing on the Switch platform. Is there any recommendation?

 

If you're doing Switch dev you should have access to their dev portal and tools.
