I’ve no idea why this is the case but it would seem that there is no FXAA on the Character Select Screen when starting the game up. You can see this from the jaggies around the edge of your character that aren’t usually present in-game.
However, after playing a character and then logging back out to the Character Select Screen, the jagged edges are smoothed out so it would appear FXAA then kicks in.
It’s not a game breaker or a major issue but just a weird annoying thing that I thought I would bring to someone’s attention
