The console and text fields aren't uncapped
When opening/closing the console, it moves at a speed defined by con_speed to make the transition look sleek. When using timescale to speed up/slow down the game, that also affects the console's speed. which it probably shouldn't(?).
Additionally, the open/close transition isn't interpolated. (In its current state, this is easily observable with timescale 0.05, where the console repeatedly jumps up/down every tic instead of sliding smoothly.)
In addition, all text input fields (the console, multiplayer chat, and text fields in the main/pause menu) only update every tic. With . Edit: This is out of scope.timescale set to 0.05, typing something feels very unresponsive, as the text field is updated less than twice per second. The blinking underscore/text marker also blinks faster/slower depending on timescale
