Yes, but in a slightly different way than one might think at initial read of this. Most of the performance choices for a user-facing application have been made by the time the language and UI framework are decided. And these are just chosen out of inertia, to conform to a company standard or to use what you already know.

There's little one can do to make a WPF or CEF application super responsive.

I'd be interested in seeing if there's a YT video out there of a WPF expert doing just that.

It might be a matter of hacking-in a caching layer or something, but it feels like probably more things are possible than people think.

A framework is just code, and you can pick-and-choose.
