Unfortunately, dynamic rendering didn't come about until "recently". Many devices are stuck on Vulkan 1.1. Go to http://vulkan.gpuinfo.org/listextensions.php and search for dynamic_rendering. It's only supported on about 28% of reports.

If you want to support those other devices you have to have a non-dynamic rendering path, and then at that point dynamic rendering is just more code. VK_EXT_shader_object is even better, but availability is that much worse.

Edit: If you are able to find a tutorial using dynamic rendering, learn with that. Render passes obfuscate what's going on, and with dynamic rendering you can see exactly what's happening.

This information is misleading because it includes old reports from years ago, before this feature existed. It does NOT mean that 28% of devices out there have support. You will need Steam hardware survey results and cross reference gpuinfo.org or Android hardware survey results which directly list Vulkan versions.

Dynamic rendering is available on all desktop GPUs (Intel, NV, AMD), on all desktop OSes (Windows, Macos, Linux) as long as you've got drivers that are up to date (no older than 2023).

For mobile devices, the situation isn't as good. Updating mobile GPU drivers is an unsolved problem.

I get your point. But you might be surprised how many PCs are still in use that have pre-Skylake Intel IGPs. Some people just don't update their drivers, either.

Pre-Skylake Intel never had proper Vulkan support (on Linux at least) so it's a non issue.

I use a 2015 Skylake laptop for most of my graphics programming project and it's got full Vulkan 1.3 and wide set of features. The hardware doesn't do mesh shaders or Ray tracing but apart from that every new feature is available.

Not updating drivers is a problem, especially on mobile. Thankfully auto updaters are very common these days.

You really have to think of Vulkan on PCs and Vulkan on mobile as separate things, if you only care about running on the former then you can easily count on things like dynamic rendering always being available as long as your users drivers are up to date. If you need to target Android though, my condolences.
