Man, and I'm here thinking it's just my VSCode that's super slow and sluggish while editing C++ code. I switch to Clion and it's surprisingly more responsive than VSCode, given Clion is a whole IDE in itself.
In comparison, programming Swift in XCode lags so much sometimes that it starts missing keystrokes, and I end up with variable names that are missing half their letters. (This happens particularly when filling in a function's arguments). Its terrible, and it leaves me second guessing the idea that native editors are superior by default. This seems to me like a much more useful target for a new IDE.
