Rocket League on Nintendo Switch will get visual modes this Spring, Xbox One X support later in the year
Psyonix posted a detailed blog entry about their plans for this year.
You can read the full post here but if you’re a Switch owner, the upcoming update is about to make things a lot better. They will be allowing users to play with 900p 60fps docked or 720p 60fps handheld. This will be performance mode. There will be a new mode called quality mode that goes for better visuals with a 30fps frame rate. Rocket League on Switch is a lot of fun but it needs this update soon because while things have gotten better with updates, it still looks poor in many areas.
On the Xbox One X side of things, they will be adding support for Xbox One X later this year.
