Releasing simply previous to the PlayStation 5 Professional {hardware} launch, Name of Obligation: Black Ops 6 incorporates a set of distinctive enhancements over base PS5 – the place now we have equally distinctive insights because of a current journey to fulfill the sequence’ Principal Rendering Engineer, Michal Drobot, and the proficient staff at Infinity Ward Poland. Black Ops 6 is developed by a number of studios – mainly Treyarch and Raven Software program – however at IW’s Poland workplace I used to be capable of get a behind-the-scenes tour of the instruments used to make the sport. So in essence, this piece serves two functions: to debate the Professional upgrades with enter from the builders – and to speak about a number of the wider enhancements made to the engine.
PlayStation 5 Professional’s replace has been out within the wild for a great month already, and it is clear that Black Ops 6’s upgrades run deeper than most. Some tweaks are delicate, whereas others make a extra evident distinction to frame-rate efficiency. In abstract, PS5 Professional customers get improved visible settings whereas operating at 60Hz, plus the adoption of PSSR to spice up picture high quality with 4K because the goal output. An anti-lag VRR function can also be added solely on PS5 Professional – letting us run at above 60fps whereas utilizing that default graphics mode. Past that, there is a broad efficiency increase with the 120Hz mode enabled, the place PS5 Professional reverts to base PS5 visible settings to ship the next frame-rate.
Beginning with the 60Hz mode, there are 4 improved visible settings, beginning with a 2-4x enhance in shadow decision, relying on the shadow sort and your distance to it. This primarily impacts environmental shadow maps, the place high quality is boosted throughout close to and much shadows streaking throughout partitions. The advance is a delicate, however typically welcome discount in stair-stepping throughout laborious shadow strains. Subsequent alongside, and extra remarkably, there’s the improved world illumination. Particularly, a screen-space GI technique is added only for PS5 Professional, simulating gentle bounce between surfaces. Once more it is delicate in some areas – and calls for switching between base PS5 and Professional in full display to really admire – however the pay-off is a way more correct gentle interplay between a personality and close by, brightly lit floor.
This SSGI setting is one thing the staff is particularly happy with, as a rasterised method that makes an attempt to imitate the standard of path tracing. It is calibrated to create as comparable a consequence to the staff’s inside, path traced reference, although clearly at a fraction of the price. This additionally extends to the best way ambient shade is applied. With the improved SSAO on Professional, there is a richer mattress of shade added to the scene – and most inside photographs just like the headquarters – making a extra life-like remaining body.
Display-space reflections – SSR – are additionally improved pm Professional, the place the ambition is to as soon as once more match the staff’s inside, path-traced reference as carefully as potential. In evaluating it with base PS5, the primary distinction on Professional is within the accuracy of how reflections are occluded by objects within the scene. Switching forwards and backwards on the Skyline map, PS5 Professional drastically reduces the ‘gentle leak’ round geometry – partitions, tables – because of the up to date SSGI, all of which has a domino impact within the accuracy of the reflection as effectively. All the things mixed, we get a change which may not scream at you within the warmth of Black Ops 6’s speedy motion, however it does make a smart use of Sony’s mid-gen machine to refine the sport’s visuals.
The opposite huge change for PS5 Professional is the transfer to its native upscaler: PlayStation Spectral Tremendous Decision. PSSR solely engages within the default 60fps mode, and when it comes to the uncooked metrics, runs at 2560×1440 internally, earlier than being upscaled to 4K. It is a dynamic decision too, with changes made horizontally to 1280×1440 lowest in additional excessive circumstances, to maintain a secure frame-rate. When it comes to the perceptual pay-off, the result’s a clear one, but additionally at occasions extra artefact-prone than engine’s personal {custom} TAA – as nonetheless used on base PS5. There are teething points, the place PSSR introduces white, flickering pixels in very particular scenes. This noise tends to seem more-so in darkened, shaded areas. And in evaluating the presentation of extremely effective element – like material – there may be additionally a slight smearing to the consequence subsequent to the TAA on base PS5.
Talking to Michal Drobot straight, he confirms a repair is already within the pipeline for these PSSR artefacts – one that ought to roll out quickly as soon as the related patch passes via QA. The trigger, it seems, is just all the way down to PSSR not being fine-tuned for denoising the picture in its present state. The staff’s personal TAA nonetheless has its benefits right here: it is considerably sooner for a begin. Plus, the staff’s personal TAA is custom-tailored for denoising the precise sort of output this engine generates. PSSR, it appears, works effectively in anti-aliasing the picture, however much less so in denoising the sparkle created by the sport’s shadows, variable price shading, and particularly its SSR.

Fortunately PSSR nonetheless works effectively in most scenes with the software-based variable price shading in place. For each group of pixels the sport can render at full, half, a 3rd, or quarter decision. Edges or laborious factors in geometry are rendered at full res, for instance. A type of foveated rendering is in place right here too, placing a precedence on particulars on the display’s centre, whereas there’s a fall-off in high quality in direction of the sides, or flatter, easier surfaces. VRS solely simply made the reduce 5 days earlier than Black Ops 6 launched, I am informed, and it does in the end assist squeeze the very best outcomes from every body – whereas boosting efficiency.
Talking of which, when it comes to frame-rate testing on Professional {hardware}, the consequence is an effective one. Black Ops 6 already ran optimally at 60fps on base PS5 within the marketing campaign mode, and regardless of PS5 Professional’s visible upgrades to SSGI, SSR, AO and shadows – and the taxing PSSR upscale – we preserve a 60fps lock right here. The excellent news is, no mission goes beneath the mark primarily based on my testing. That being mentioned, there’s one approach to stress take a look at base PS5 – to power a repeatable drop – within the type of its split-screen mode. Utilizing the Derelict multiplayer map, and fixing a second participant’s viewpoint throughout the motion, base PS5 suffers fixed drops to the 50fps line. Switching to PS5 Professional in the identical spot, although – and conserving that second participant view in the identical place – we’re now nearly solely on the 60fps line, barring just a few single dropped frames. In different phrases, we get the visible enhancements, and the place the GPU is burdened, Professional can also be capable of hand in higher efficiency.
There’s one different technical advance for PS5 Professional, within the type of an ‘anti-lag’ VRR expertise on this 60fps mode. This engages as long as you’ve a 120Hz VRR show related, however particularly maintain the 120Hz mode disabled within the recreation menu. Developed together with Sony, an additional API name is made on PS5 Professional this manner, to foretell the upcoming frame-time. On this case, reasonably than VRR getting used to cover drops below 60fps – as is frequent in so many video games – Black Ops 6’s VRR is as an alternative used to render frames sooner, and go above 60fps the place there’s funds for it. That is achieved via logical prediction. Primarily based on a number of earlier frames, the engine is actually capable of recognise the place there’s ‘slop’ – or, a reliable chunk of frame-time that’s repeatedly not getting used inside a 16.7ms funds for 60fps. And through the use of that slop, it is capable of generate a body earlier, reducing latency within the course of, from the controller enter to a displayed body.
The result’s extra frames per second than would in any other case be potential. In most eventualities by myself VRR show, frames are literally output at wherever between 60-120fps, however usually efficiency hangs between 80-90fps in the course of the opening mission. Just one main drop, briefly below 60fps, is recorded whereas exploding a planted C4 on the open world missions. Past this, the VRR mode genuinely works, and the staff declare it to be extra responsive than operating the sport unlocked with the sport’s precise 120Hz output mode energetic.
The precise 120Hz mode on PS5 Professional, conversely, removes the entire new options: the visible upgrades, the PSSR, and in addition that anti-lag VRR expertise. As a replacement, Professional {hardware} as an alternative runs at 1440p internally with the staff’s in-house TAA, utilizing the identical high quality settings as base PS5’s 60Hz mode. In direct comparability between base and Professional consoles, we’re seeing an uptick in efficiency by as a lot as 35 % right here too. Spots the place the sport suffered from dips to 95fps beforehand, just like the preliminary stroll ahead on the primary mission, now run at largely 120fps. We don’t have an ideal lock on PS5 Professional nonetheless – and drops to 100fps are nonetheless very potential – however the margin is tightened now.
As an apart, the rationale PSSR is unused right here it appears is partly the frame-time price: it takes up 2.1ms of the frame-time, which in its present kind is just too nice a piece of the required 8.3ms frame-time required to run at 120fps. Later, improved variations of PSSR may pace this up, however for now the TAA is healthier suited to 120Hz. In an identical vein, I am informed the concept of utilizing PSSR to permit for a theoretical 8K decision mode in Black Ops 6 poses an identical problem. Briefly, an 8K body is 4 occasions the pixel output of a 4K one, which for PSSR’s reconstruction, equates to a 4 occasions enhance within the frame-time price.
Past PS5 Professional, there are an important many new engine options making a debut in Black Ops 6. To show every, Michal booted up a so-called ‘white room’, a neatly labeled take a look at suite that lets us see every facet of the engine operating in isolation. From materials lighting to volumetric fog, particle results, or terrain streaming – all components of Name of Obligation’s tech has its personal small torture chamber. It presents as a science experiment on this approach; a method for the event staff to zero in on new applied sciences, for Black Ops 6 and past, earlier than they really ship.
Among the many many new additions to the sport is climate grade volumes – or WGVs. In a nutshell, WGVs permit mud, water, oil, or snow to depart a persistent mark on a participant’s physique – with solely the precise physique half coming into contact being affected. It is best proven off in third individual view, although in practise you may see it on enemies throughout gameplay. One nice dev footage instance despatched by the staff has a participant stood subsequent to a 4×4 car; the acceleration of the rear wheels causes mud to spray upwards, the place the momentum of the automotive, and the speed of the spray is simulated by massive spherical volumes. These WGVs continuously regulate and alter primarily based on the place, after which, to measure the purpose of that mud’s impression on the participant, a 3D voxel-based system is used on the participant.
An grid of voxels cowl the participant rig with each individually triggering primarily based on contact with mud, water or snow. It is a approach to pattern the impression of results, and even climate situations. Put in our personal instance, trying on the oil fires of mission one, the best way oil droplets construct up on our fatigues provides a observe of realism – whereas in multiplayer it offers a touch as to the place the enemy participant has final been.
One other spotlight of current video games is the dealing with of terrain, which breaks down into a number of layers. First now we have the digital texturing system – or ‘tremendous terrain’. This was debuted in Warzone, and effective tuned in 2021’s Vanguard, permitting a large, detailed texture map to be generated procedurally forward of the participant. We’re speaking digital acres of panorama that adjusts its element primarily based on proximity and participant view. That is helpfully put in instance utilizing the dev instruments, which present how the general texture map is stuffed out in tiles – crucially serving to to handle system reminiscence.
Subsequent, operating on high of that, is the grass. For Name of Obligation, the presentation of grass throughout a number of consoles is fastidiously balanced – to make sure visibility stays the identical for on-line, cross-gen matchmaking. Density and draw distance are matched to keep away from a aggressive benefit for any participant – and, you may discover, reasonably than grass blades popping in abruptly, they’re in actual fact merely lowered beneath the bottom to ease the transition.
Rounding out, there’s the deformable terrain. The marketing campaign modes of current Name of Obligation titles embody litter, or deformable grass, which leaves a path as you crawl via. It is maybe greatest proven off within the white room footage, in a singular ‘vertex deform’ space that lets the participant paint their route via a small backyard patch. Likewise, now we have deformable snow for ranges that want it – achieved by way of tessellation.
It is one other instrument within the field for builders to make use of. Once more vertex deformation is a comparatively new function for the sequence, letting thick layers of snow seize participant motion at a excessive decision – the consequence being a persistent path. All of this helps gamers depart a tangible mark on the world, particularly within the marketing campaign. Final however not least, now we have the addition of superior glass. That is used even throughout Black Ops 6’s multiplayer maps immediately, to simulate the gradual fracturing and structural breakdown of a glass pane. The integrity of the glass breaks down with every shot, which even components within the glass pane’s thickness, whereas lighting from behind the glass is realistically simulated because it hits the pane.
The variety of additions made to the sequence, and Black Ops 6 particularly, are too quite a few to completely cowl right here. There are enhancements to the sport’s fog impact – with screen-space fog gathering used extra extensively throughout every map, after being launched in Fashionable Warfare 3. There are additionally enhancements to water caustic simulation – in choose moments – including reflections and refractions from the lit water floor. All of those factors are enormous labours of affection for the staff, and given the speedy nature of the sequence’ motion, do not at all times get the credit score they deserve – the important thing takeaway being that each Name of Obligation title pushes the technical envelope in myriad methods.
Black Ops 6 continues that evolution, in some respects constructing on the applied sciences and concepts in Vanguard, Warzone, and Fashionable Warfare 3, whereas additionally pioneering new ones. With the launch of PS5 Professional particularly although, the staff seized an opportunity so as to add some new options: the anti-lag VRR mode, the adoption of PSSR, the improved world illumination and reflections. It is a end result of years of labor, the place PS5 Professional is highly effective sufficient to finally facilitate every function within the console house.
