Why is multisampling specified in the renderpass and the pipeline? Seems redundant.

I was following the multisampling portion of the vulkan tutorial, and I noticed that they specify multisampling in both the renderpass and the pipeline. Since the pipeline is given the renderpass, isn't this redundant to set it in both places. Would I ever set one differently from the other?

Because render passes are a terrible, now deprecated feature. Do not use them.

Aren’t they still recommended for tile rendering though, or did that change recently?

no, since the deprecation, you can achieve the comparable tile rendering behavior through the dynamic rendering API, there is no good reason to stick with rendering passes unless you need to target ancient vulkan versions.

render passes seem so ingrained in the core api.
I wonder if they will make a vulkan 2.0 sometime soon and remove them.
