The suspicion may also be induced by other software.

Ever tried early RStudio (or even current) on a crappy work-issued laptop? And I don't mean R, I mean the UI elements.

This is a great piece of software, certainly more than a text editor. But it isn't as fast and snappy as a native editor, far from it. It's tolerable now, but it used to be pretty bad on non beefy hardware.

At the same time, native IDEs did not have that issue at all.
