Just bought it on impulse. But now wondering if I should have. Haven't actually opened it yet. However I'm finding it difficult to get any info on resolution and frame rate. Is it 1080p native on both PS4 and Xbox One or what? Also, frame rate? Any discrepancies between the two? Constant 30fps on both?

Keep calm and carry on or take it back and swap it for the PS4 version? I only ask this because there'll be a niggle in the back of my mind when playing it if there is.

If the Internet is to be believed it is 1080p and 30fps on the XBox ONE and the PS 4.

Well, if you've got access to both consoles, you really should be aiming towards ps4 on all multi platform games. As for resolution, if the borders are painted then it should be 1080p, if not then around 800p. Framerate wise, it's not exactly cutting edge so you should be fine there.

Sounds like bad advice for this game.

PS 4 reviews seem to be complaining of stutter and frame rate issues that don't appear on the XBox ONE.

Not issues that I've come across in the XBox ONE version yet but technically they're supposed to be the same.

Runs like crap on PS4. Looks like 20fps at times. If you care about performance, from what I've read, it doesn't appear to be performing well on any system. AVOID!
