To mark its fourth anniversary, developer Housemarque has introduced a free PlayStation 5 Professional improve to Returnal, promising to present an outstanding PS5 recreation a decision increase of as much as 2.5x on Sony’s Professional {hardware}. The precise phrasing of “as much as 2.5x” does recommend a type of dynamic scaling is in play, which I will 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 some other enhancements to the unique expertise? Are the efficiency points addressed and what in regards to the slight traversal stutter points?
As a refresher, base PS5 to at the present time makes use of a hard and fast 1080p base decision, which – in response to the developer – is temporally reconstructed to 1440p, after which upscaled to a closing 4K output by way of checkerboard rendering. Whereas the sport is brilliantly executed in its core expertise – with particles typically filling the display screen 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 any case, however excessive frequency element seems reasonably grainy within the closing 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 provides 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, mounted 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, probably 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. Fairly, this greatest 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 count on. Admittedly, the fast tempo of Returnal’s motion signifies that a decision increase will not at all times 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 arduous edges, and notably, any sudden burst of results, the place the pixel construction seems in its uncooked kind for a number of frames, you will discover much less aliasing.
Regardless of the improve, the PS5 Professional model nonetheless has some temporal instability, with an identical cross-hatch impact to base PS5 because it upscales to 4K – although the artefact is subtler on Professional as a consequence of its total larger pixel density. It isn’t completely clear in each body: there are uncooked edges if you understand the place to look, however they are much finer steps at 1728p. Secondly, a 2.56x improve just isn’t sustainable in each situation. PS5 Professional presents a 1.45x increase in GPU energy over the bottom mannequin in any case – plus 45 per cent – which is misaligned with the calls for of that res increase.
That is exactly the place dynamic decision scaling makes an influence: we’re extracting the very best high quality frames the place GPU headroom permits it, whereas at its lowest level, picture high quality remains to be higher than base PS5. On hindsight, it is a disgrace that the bottom PS5 is not retrofitted with DRS as nicely. 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. Fairly, it is a easy, however direct option to route PS5 Professional’s larger GPU sources.

All of which brings us to the subsequent level that, truly, there have been various routes to utilizing PS5 Professional. There are different attractive choices that might 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, at the same time as an non-obligatory RT mode. Right here it is unusually not even been thought of and so it stays a PC unique characteristic. 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 solely one single option to play, with no graphics toggle to talk of – nevertheless it delivers on what it got down to do.
Efficiency testing is difficult. 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 nicely at 60 frames per second, although there are definitely drops underneath the goal. It is unusual, however underneath 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 typically 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 strong 60fps expertise, with solely traversal stutters between areas – a number of one body blips – value noting.
Leaping to PS5 Professional it is attainable to recreate not 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 totally cleared up at a steady 60fps on Professional. Between its larger GPU clock pace, and higher flexibility afforded by dynamic scaling, we’re in a position to lock tightly at 60fps now in each areas, which is nice. General, the DRS scale between 1350p to 1728p seems nicely 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 absolutely patched is theoretically extra steady. The transfer away from a hard and fast 1080p on a base PS5 provides it extra leeway to adapt to the maelstrom of results which can be attainable from second to second. With that being stated, there’s a small catch.
Like-for-like efficiency testing in a roguelike is difficult, however the place we will evaluate, PS5 Professional irons out all the frame-rate drops we may discover on the unique PS5 model, whereas delivering larger total decision. | Picture credit score: Digital Foundry
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 cut up second to regulate its decision to an surprising spike in load, inflicting a higher spike on the body time graph.
Talking extra typically on Professional efficiency, it is value noting that point could nicely 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 solutions there that it maybe ran higher in a pre-patch state on Professional, utilizing the bottom PS5’s rendering setup. That could be the case allowing for the conservative decision goal of the legacy code which Professional ought to effortlessly energy by means of. 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 bold use of Professional {hardware} – however the extent of the elevated pixel counts is stunning. The place there’s a 2.56x increase to decision, we’ve 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 total: the one minor catch is a better prevalence of 50ms frame-time hitches simply on placing an enemy, however the execs outweigh the cons in attending to a extra steady 60 frames per second with a major picture high quality improve. Returnal itself stays top-of-the-line shooters ever made and with that in thoughts, the Professional improve is a good alternative to revisit certainly one of this technology’s all-time classics.
