To mark its fourth anniversary, developer Housemarque has introduced a free PlayStation 5 Professional improve to Returnal, promising to offer an excellent PS5 recreation a decision enhance of as much as 2.5x on Sony’s Professional {hardware}. The precise phrasing of “as much as 2.5x” does counsel a type of dynamic scaling is in play, which I am going to get to in a minute – nevertheless it’s a welcome transfer that addresses one gripe with base PS5’s picture high quality. Past that, are there another enhancements to the unique expertise? Are the efficiency points addressed and what concerning the slight traversal stutter points?
As a refresher, base PS5 to today makes use of a set 1080p base decision, which – in keeping with the developer – is temporally reconstructed to 1440p, after which upscaled to a remaining 4K output by way of checkerboard rendering. Whereas the sport is brilliantly executed in its core know-how – with particles usually filling the display to dazzling impact – this uncommon setup does trigger some visible noise on the usual PS5. It is a hardly a dealbreaker and gameplay is king in spite of everything, however excessive frequency element seems somewhat grainy within the remaining resolve. It definitely falls in need of what the PC model is able to, even at a local 1440p by way of DLSS.
To chop to the chase, the PS5 Professional replace offers us a lift to 3072×1728 at peak, with dynamic decision scaling in place to regulate to GPU load. The introduction of DRS is new to the Professional model, changing the static, fastened 1080p of the bottom PS5 – which does have a small bearing on frame-rate. The bottom determine on report on PS5 Professional in the meantime is 2400×1350, caught throughout intensive boss battles the place the frequency of screen-filling results is most apt to hammer the GPU. Decrease figures may be attainable in fact, doubtlessly in later areas. Even so, that most attainable 1728p on Professional is a surprisingly frequent occasion throughout the primary three biomes I’ve examined, and in reality, over-delivers on Housemarque’s promise of a 2.5x improve. Relatively, this finest case worth is nearer to a 2.56x improve over base PS5’s static 1920×1080 decision, which is a pleasant bonus.
The lead to evaluating PS5 to PS5 Professional pans out as you’d anticipate. Admittedly, the fast tempo of Returnal’s motion implies that a decision enhance will not all the time scream at you, however, supposing you need to take within the sights at your leisure, this a transparent improve. Specializing in staircases, or detailed ground textures, the moire patterns current on base PS5’s are minimised. The flickering is lowered on laborious edges, and notably, any sudden burst of results, the place the pixel construction seems in its uncooked kind for a couple of frames, you may discover much less aliasing.
Regardless of the improve, the PS5 Professional model nonetheless has some temporal instability, with an analogous cross-hatch impact to base PS5 because it upscales to 4K – although the artefact is subtler on Professional attributable to its general larger pixel density. It is not completely clear in each body: there are uncooked edges if the place to look, however they are much finer steps at 1728p. Secondly, a 2.56x improve isn’t sustainable in each situation. PS5 Professional affords a 1.45x enhance in GPU energy over the bottom mannequin in spite of everything – plus 45 per cent – which is misaligned with the calls for of that res enhance.
That is exactly the place dynamic decision scaling makes an impression: we’re extracting the best high quality frames the place GPU headroom permits it, whereas at its lowest level, picture high quality continues to be higher than base PS5. On hindsight, it is a disgrace that the bottom PS5 is not retrofitted with DRS as properly. This Professional patch does precisely what it says on the tin then. No different visible upgrades are in place: volumetrics, alpha results, textures and shadows stay the identical as earlier than. Relatively, it is a easy, however direct technique to route PS5 Professional’s larger GPU sources.

All of which brings us to the subsequent level that, truly, there have been different routes to utilizing PS5 Professional. There are different engaging choices that would have been explored, like a 120Hz mode – even when it necessitates a decision drop to carry a gentle 120. The opposite route may have been including the PC model’s ray tracing options. Ray traced reflections and shadows aren’t important – and certainly, every comes with its personal limitations on PC – however would have been fascinating to see on Professional, whilst an optionally available RT mode. Right here it is unusually not even been thought-about and so it stays a PC unique function. Likewise, lots of PC’s epic presets keep landlocked on PC – just like the improved volumetrics decision. What we’re left with on Professional is just one single technique to play, with no graphics toggle to talk of – nevertheless it delivers on what it got down to do.
Efficiency testing is hard. The extremely randomised nature of Returnal’s roguelike design means actual 1:1 checks between PS5 and Professional aren’t attainable. To recap: base PS5 runs properly at 60 frames per second, although there are definitely drops beneath the goal. It is unusual, however beneath the fitting circumstances, frame-rates can dip. For instance, the primary boss battle within the preliminary Overgrown Ruins stage drops into the mid-50s, and likewise, there is a smaller diploma of sub-60 drops throughout main battles within the Tower of Sisyphus. One other outlier is on respawning again on the ship: there’s usually a short, uneven passage of play – lurching to the 40s for spell – although this quickly clears up on base PS5 as Selene stands upright. Lastly, I did discover a extremely uncommon level at a staircase within the first biome – with seemingly nothing occurring forward – dropping us to a relentless 55fps. These are our actual outlier moments to a typically stable 60fps expertise, with solely traversal stutters between areas – a couple of one body blips – value noting.
Leaping to PS5 Professional it is attainable to recreate no less than a few of these moments. The excellent news is that boss battles, just like the one bookending the primary biome, and on the Tower, are solely cleared up at a secure 60fps on Professional. Between its larger GPU clock velocity, and larger flexibility afforded by dynamic scaling, we’re in a position to lock tightly at 60fps now in each areas, which is nice. Total, the DRS scale between 1350p to 1728p seems properly judged and targets PS5 Professional’s capabilities sensibly. It is also good proof that, whereas there could also be drops in later, randomised configurations of a stage, and with sufficient progress, PS5 Professional totally patched is theoretically extra secure. The transfer away from a set 1080p on a base PS5 offers it extra leeway to adapt to the maelstrom of results which might be attainable from second to second. With that being stated, there’s a small catch.
Traversal hitches stay, and there may be additionally a barely larger frequency of hitches to 50ms on PS5 Professional – a number of dropped frames – simply as an assault lands on the enemy. Maybe PS5 Professional wants a break up second to regulate its decision to an sudden spike in load, inflicting a larger spike on the body time graph.
Talking extra typically on Professional efficiency, it is value noting that point might properly reveal extra important drops. Nonetheless, after a number of days taking part in PS5 Professional as much as the third biome – and thru the Tower space – I didn’t catch main drops in any other case, as but. That is not the ultimate phrase: given the sport’s randomised nature, extra taxing areas are definitely very attainable. Certainly, posters on Resetera are noticing frame-rate dips with the Professional patch put in with recommendations there that it maybe ran higher in a pre-patch state on Professional, utilizing the bottom PS5’s rendering setup. That might be the case taking into account the conservative decision goal of the legacy code which Professional ought to effortlessly energy by. That apart, the outlook is constructive primarily based on the proof of matching stress take a look at areas: PS5 Professional is an enchancment over the bottom mannequin in holding 60fps, plus we’re getting a sharper picture into the cut price too.
As out of the blue because the Professional Returnal patch is, followers will little question be delighted that the sport is getting extra consideration from Housemarque. Decision and efficiency boosts maybe aren’t probably the most formidable use of Professional {hardware} – however the extent of the elevated pixel counts is shocking. The place there’s a 2.56x enhance to decision, we’ve got to surprise if dynamic decision scaling alone accounts for the distinction when the Professional itself solely delivers 45 % extra graphics efficiency. Even so, the improve is spectacular general: the one minor catch is the next incidence of 50ms frame-time hitches simply on placing an enemy, however the execs outweigh the cons in attending to a extra secure 60 frames per second with a big picture high quality improve. Returnal itself stays among the finest shooters ever made and with that in thoughts, the Professional improve is a superb alternative to revisit considered one of this technology’s all-time classics.
