Idk about subpixel font rendering, but font rendering on Linux looks massively better after a patch last week: https://github.com/zed-industries/zed/issues/7992#issuecomme...
They aren't high-dpi though, just big and still zoomed. On the plus side, it's very similar experience to two 4:3 monitors glued together... side by side apps on half the screen is a pretty great experience... on the down side, RDP session suck, may need to see if I can find a scaling RDP app.
> does we run game engine for code??
Zed literally does this; they render their UI using a graphics library just like a video game.
