con_scaletext
0: Disable message scaling.
1: Enable message scaling.
This variable controls the size of the messages that appear at the top of the screen (such as "Picked up a Stimpack"). When enabled, the text is scaled up to match your resolution. When disabled, it displays pixel-for-pixel, which may be unreadable in some higher resolutions. Please note that this variable does NOT effect how big the console font is.
