I am also experiencing this annoying issue. My peripheral vision can't see the GEAR & REV meter (placed so low on the screen) unless I move the "F1 Dial" GUI for the gears upward to the Halo barrier. The Time Trial OSD customization feature just will NOT save my personal mappings; nor is there a Filter for Time Trials in the OSD customzation area. I only see Filters for: Normal, Pit and Supercars.
Lastly, why are the OSD Customization & Map Rotation sections disabled within the OPTIONS|Settings area from the main menu before going to F1 World? I mean every other setting can be tweaked but OSD & Map Rotation? Come on now! And why force drivers to go deep into the new F1 23 game menus, scrolling through a ton of areas before we can finally customize OSD features? We're forced to go into a GP Session, or a TT Session first, select a car, then pick a track, then wait for the game to upload the session, then click, click and more scrolling and clicks. SMH. Simply put, just way too many layers to get to a base-level OSD Customization before hitting a track.
NB: The first update for F1 23 (v1.6.1006145 June) has removed OSD Customization from the Time Trial|Settings main menu. Now, it can only be accessed via the PAUSE MENU|Settings|OSD-Customization menu while on track in a Time Trial session...and it still won't save. SMH.
Simplifying, how we access OSD across ALL menus would be helpful and having PERMANENT access to OSD-Customization no matter where you are in the game. Why hide ANY game setting?
