Better text chat can be installed via Mod Manager. It increases the font and duration from 3s to 8s. This is a client side only mod. Only YOU, the person who installed this, will benefit from it. Other players won't have any difference. This patch makes moves in game text chat more towards the center of the screen vertically, have a larger font, and last 8 seconds instead of 3.
