Xbox One Requires Day One Resolution Update for Trials Fusion
In order for Xbox One Trials Fusion players to enjoy 900p resolution they'll have to download a day-one patch.
Without this patch the game only runs at 800p, 60fps. If you are more of the 1080p type of player, then PS4 and PC have that for you. Honestly, it's not that big of a difference so go with whatever makes you happiest.
I'm still debating which platform to get it on. Which one are you buying it for?
