Does anyone have experience with virtual textures?
sublime tool
Those huge ones that allow to load only a part at a time ? I wonder how big you go and what texel size you are using with them. And what method to create them do you use? Are they really that quick on modern hardware?

See the UE5 one!
Authoring wise - they're just textures...
With unreal they work fine on current gen consoles and were usable on PS4/xbone but you had to be very careful how you schedule updates due to a lack of memory bandwidth.
Outside of unreal the tech is called sampler feedback and depends on direct storage (and I think bindless resources) to function. I posted a link to a Microsoft presentation about it recently.
The primary benefits are that you basically don't have to worry about static memory footprint for textures and you that don't have to limit the size of your top mips.
The caveats are that there's overhead attached and you need certain systems in place that are non-trivial to implement.
The difference is that it loads parts of textures, not the whole thing
We had to do a fair bit of balancing and tweaking to avoid issues with the time taken to update the list of 'tiles' we loaded on PS4 and xbone because they had so little memory bandwidth - gen 9 consoles and pc were much more forgiving
We've shipped non-unreal titles with this tech on gen9 and it's been fine.
In essence you're concerned about the right sort of thing but I don't think you need to be unduly concerned
