Let's go through each of the consoles in turn, starting with the base Xbox One edition - the most constrained last-gen console. Xbox One runs at a native 1600x900 resolution with a 30fps target that's mostly stuck to - there are occasional hitches and single frame drops, triggered by UI changes or picking up a weapon, but it's a surprisingly smooth experience that shows evidence of plenty of optimisation and no signs of dynamic resolution scaling during our testing.
Switching over to base PS4, it's again positive, with a native 1080p presentation and the same core visual settings as the base Xbox One. However, the 30fps frame-rate target isn't held quite as well, with slightly more aggressive hitching in places - but most areas remain a watertight 30fps. Note that neither base PS4 or Xbox One are able to host online games at launch - PS4 Pro, Xbox One X or a current-gen console are required to host sessions, although Dambusters is aiming to address this restriction in the weeks following launch.
Next up are the enhanced machines: Xbox One X and PS4 Pro. Both consoles use the same visual settings as their older counterparts, with textures, shadows and alpha effects all matching, but push a crisper image with a native 2560x1440 presentation. Again, the frame-rate target is 30fps, with each machine sticking to it almost perfectly, with rare incidences of one frame dips but overall a robust experience all around.
For current-gen console owners there's even better news. PS5, Series X and Series S each get a push to 60fps, and in the case of PS5 and Series X there's a sizeable resolution boost as well. The PS5 version runs at a native 3072x1728 with a perfectly-held 60fps, while Series X targets the same resolution and also hits 60fps outside of a few brief drops while using elemental attacks. Jumping over to Series S, performance remains excellent with only occasional drops from the 60fps target, with heavier effects work causing frame-rates to drop into the high 50s in rare instances. However, resolution is lower than on the other current-gen machines, with a native 1920x1080 presentation - a fair trade for 60fps, I think it's fair to say.
