  • Performance Analysis: Mirror's Edge Catalyst

    With the switch to Frostbite 3 for this reboot, Mirror's Edge Catalyst targets a 60fps update over the 30fps of the original's last-gen debut. On sampling the beta a few weeks ago, the upgrade in smoothness and controller response was immediately apparent, where gameplay felt far more refined as a result. However, frame-rates were far from stable, and while PlayStation 4 handed in a decent level of consistency, Xbox One often struggled to hit 60fps for long stretches of play. But DICE prides itself on its optimisation skills, and the good news is that the final game offers a substantial performance improvement over the beta.
    That translates into a much tighter lock on the target 60fps. The boost to performance is fairly light on PS4, but there are major gains on Xbox One, where the experience is considerably smoother than our last look at the game. In the beta, frame-rates fluctuated between 40-60fps across a general run of play, but now, performance rarely gets in the way of the action - outside of a few demanding scenes.
    Some sequences still cause notable issues though - an escape from Elysium Labs causes frame-rates to come down to 40fps at one rare point, as the engine appears to struggle with streaming in data for the next map segment. The situation here isn't great, but on the plus side, performance rarely drops this low for too long - and in the final build, this level of instability doesn't last for longer than a second. As a result, with the optimisations made by DICE since the beta, the experience on Xbox One is now broadly on a par with the PS4 game in terms of baseline performance.
