That's correct. The hello triangle samples deliberately do their own sync to make them as stand-alone as possible. Other samples use different (and simplier) means of syncing. If you want to learn how to properly sync in Vulkan take a look at one of the hello triangle samples.

Hello, Sascha
Thank you for your answer just before
and sorry for this reposting

But I have one question

May I change the name of the variable waitFences (in Triangle example) to something like waitTriangleFences ?
Is it not better to have different names ?
I wonder why we have the same name for two different variables

Please help me more about this. Thank you

See #871 for plans on updating other samples to use that way of sync.

Please note, this is for reporting issues regarding the samples. I don't answer general Vulkan questions in here. This has some community links where you can ask such questions: https://vulkan.org/learn

OK, I understand. Have a nice weekend, Sascha
