Sublime is still the fastest(opens instantly), and personally it looks better than VSCode with the new adaptive themes. Font rendering on MacOS is native in Sublime instead of the fake blurry stuff you get with Electron.
Wheee, I'm not the only one bothered by this! It's bad on Windows too, though Linux is fine. It affects all Electron based programs, including Chrome itself.
I'm not sure if this addresses files bigger than 10mb though.
