A 1920 byte (80x24x1-byte each) character window shouldn't be having performance problems on modern systems (ie: seeing blank-characters or whatever) when a 1080 x 1920 x 4-byte == 8MB desktop completes any execution faster than the eye can see on 30 year old hardware (blank, redraw, scale, etc. etc.) Something, somewhere, is flushing the screen and waiting for V-Sync, or something like that. You can write a 2D Canvas or even 3D world (involving the reupload of entire geometries each frame) that executes faster in Javascript compared to this 80x24x1 byte TUI window.
