When Rocket League launches on Switch, you can expect it to run at 60 FPS and 720p. This applies to both docked and portable modes. The team is prioritizing performance over visual fidelity, hence the decision to settle on 720p.

I like these guys already.

That works for me.

I can get behind this. 60fps > resolution imo

Quit reaffirming my decision to day one this game.

Yes because there's so much extra space for a desktop-level GPU in this:

OP: Works for me, I'll take 60 FPS over 1080p personally, especially for a game like Rocket League.

Wonder how it will look on the big screen when docked, hopefully not too blurry. 1080p mode makes sense when on the go though.

60, 720 > 30, 1080. I will say it would be even nicer if people were given the option to choose between the two.

No problemo!

Stuff like Rocket League unfortunately tend to make for fairly poor reference points, because their technical cap is significantly lower than what the PS4 and X1 can do. It's why even the standard X1 can run it at 1080p/60fps/Max~. Such comparisons tend to favour lower spec hardware, since less of its available power tends to go to waste. So it shows us what the Switch can do, but not what it can do relative to the PS4 and X1.

A good reference point would be a technically impressive title the PS4 and X1 have to make significant compromises on versus the game's technical cap (e.g. The Witcher 3), and from a developer willing to properly optimise for all platforms. The best example we have right now is DQH2, where the differences is 1080p vs 720p, 45-60fps vs 20-30fps, and graphical downgrades on the Switch. Unfortunately even DQH2 is a relatively lacking comparison, because it's not particularly well optimized on anything :p
