RML, I replied to your email.
PUBG is coming up on the planned list.
A grounded relook is still planned but resources are limited so it can't be a priority during fall AAA game releases.
Unfortunately PS5 is not a supported platform at this time. I recommend trying the other fortnite configs, using other game settings if needed. Try using the recommended settings (

Halo Infinite multiplayer support is in progress.
