I've been using this for a few hours now, main issue I have is the text on the computer consoles you can hack and droids you can repair doesn't show up.
I also had two other issues but I consider them minor. The chat bubble that pops up from random npc that don't have dialogue cutscenes doesn't show text most of the time and as other users mentioned you can't see the amount on some things, like currency when you loot.
I'm using the 50% increase on 1440p resolution, I've installed all mods from the kotor community portal build guide. This is the only extra mod I've added outside the build guide.
EDIT: Update after a few more hours I switched to the 30% increase that other users said worked better. I could now see computer console options and droid repair options but I also found new issues.
The minor issue was not being able to see the play time on saves. The major issue was the game crashing to desktop when opening some boxes, specifically I remember 1 box in the Korriban cantina and another in a room you spawn later in the same planet, took the mod off and they opened without issues after a google search said other font mods had the same issue.
