Bigger HUD Fonts
When the Activate Big Font in HUD box in the TSH Manager is checked, bigger HUD fonts will be used at all screen resolutions. These can increase HUD legibility at higher resolutions. Below are comparison screen shots of stock fonts and big fonts at a resolution of 1024x768. Note that there is a known issue with big HUD fonts where the AIM-120 AMRAAM TTG and TTA cues are sometimes displayed in both big and small fonts simultaneously. There is currently no fix for this issue.
Since the fonts are still fixed-height (TSH has only changed some of the HUD to use a bigger font, not made the font scale with resolution), it can still be hard to read the HUD at high resolutions (i.e. 1680x1050, 1920x1200, etc.). Unfortunately there is nothing that can be done to improve the situation.
