Whenever I switch to another dev's machine, usually running either jetbrains or vscode, I'm always astounded at how annoyed I find myself while typing on it due to the high latency on keystrokes. I'm blessed with ~subframe delay using st (https://st.suckless.org/) and neovim, and now I don't know if I could ever go back to a "true" IDE for professional work.
Just for kicks I've started work on my own text editor to see how little latency I can get. I figure I have to write it in C with vulkan for minimal latency. Typometer is critical for testing here. I've already matched the latency of st and neovim, but I think I can get lower by moving away from glfw and using X11 directly, and maybe by figuring out some clever vulkan sync method.
