Yes, I can perceive that latency, if I am actively looking for it. No, it has absolutely no effect whatsoever on my ability to work. The latency is far, far below what could possibly affect neural feedback loops, even on the slowest editors. And it doesn’t bother me in the slightest.

Low-dpi font rendering also isn’t an issue for me, unless it is so bad as to be illegible (which no modern system is).

We really do perceive things differently.
