So perhaps wisely, 60fps at a resolution more befitting a 4K display remains the norm. Where this happens, FPS Boost isn't enabled by default - you need to drop into the game's compatibility menu to enable it. So in essence, despite Series X offering twice the notional graphics performance of Xbox One X, we're looking at often substantial reductions in resolution to make a consistent 120 frames per second happen.

And in fact, in the course of our testing, we also discovered the price to pay for doubling frame-rate on the more expensive machine - Xbox One X enhancements (which usually manifests in the form of higher resolution) are disabled. The full list of supported titles is reproduced below and as you can see, not every single game in the list gets an upgrade if you're gaming on Xbox Series S - certain games are only 120fps-capable on the more expensive Series X. But to cut to the chase, every last-gen Battlefield game for Xbox One now runs at 120 frames per second on Series X, as does Titanfall and its sequel, and that's just the beginning.

MIRRORS EDGE 2 GAMEPLAY UPDATE
Last week, Microsoft upped the ante with its FPS Boost campaign, delivering 120fps upgrades for 12 Electronic Arts titles and an extra 60fps update for one other - and it's a terrific bonus for Xbox Series console users, albeit with a caveat or two we'll come to shortly.
