This is a problem for Nvidia’s new prime-tier RTX hardware that is very, very totally different from the same old benchmarks and gameplay checks – is it truly doable to run the deeply flawed PC port of Batman: Arkham Knight at 4K decision at a clean, locked 60fps? Three years on from its extremely controversial launch, has the standard of the port improved at all? Can the most recent mainstream PC expertise attain the constant efficiency degree that has historically eluded this most baffling of ports? And maybe extra to the purpose – why return to Arkham Knight at all?
The final level is the simplest to reply – it is about preservation, the concept of operating one of many best video games of this era not simply on the video games machine of right this moment however on the hardware of tomorrow. Publisher Warner Bros has already taken a swing at remastering the PS360 period Arkham titles for the present era of consoles with restricted success, whereas Arkham Knight itself has acquired no help for the improved Sony and Microsoft machines. Through that strategy of elimination, the PC model is all we’ve got to work with when the following best various is the 1080p30 PS4 expertise operating beneath increase mode on PS4 Pro.
And what’s clear from operating the PC sport at larger resolutions is that Rocksteady’s authentic belongings not solely maintain up at 4K, they give the impression of being completely lovely. While among the core results like depth of discipline or the sport’s signature rain do not scale to larger pixel-counts so successfully, the excessive frequency element, the beautiful character modelling and the sheer ambiance of Rocksteady’s open world Gotham is solely phenomenal when pushed to the following degree. Even earlier than we try to tug the PC model kicking and screaming to 60fps, what we’ve got here’s a fascinating ‘what if’ – a imaginative and prescient of what Arkham Knight operating on the improved consoles might probably deliver.
But it is the efficiency situation that’s our greatest problem right here – matching the consoles’ 30fps goal isn’t any actual downside. In principle, this must be simply doable. Running the sport unlocked on highly effective hardware simply sees the sport recurrently function effectively north of 60fps – however common body-charges should not the difficulty, it is all in regards to the extremely intrusive stutter that brings efficiency crashing down. Returning to Arkham Knight and operating the PC port throughout a variety of hardware, there are a number of points to sort out right here.
First of all, except you want tearing loads there is a double-buffer v-sync to cope with that can simply ship body-charges crashing down from 60fps to 30fps in a blink of the attention. Secondly, background streaming – sure, the dreaded Batmobile sections particularly – additionally inflicts a level of stutter, and that is probably right down to streaming points baked into the core Unreal Engine 3 expertise. Then there’s bandwidth intensive areas in minimize-scenes, which can drag efficiency down onerous. Just play by the preliminary diner scene, or the place the Joker is torched at the sport’s very starting for a few examples of this.

So how can we take care of all of those points? For Nvidia customers, utilizing adaptive v-sync (we suggest the GPU management panel flavour) and a max in-sport body-fee set larger than 60fps trades occasional display-tear for the lurching body-fee drops attributable to the double-buffer v-sync set-up. It’s not splendid, but it surely’s a transparent enchancment in total fluidity. The bandwidth intensive scenes are more durable to sort out, however based mostly on RX 580 and Vega 56 testing, this might not be as a lot of a difficulty for AMD hardware, which appears extra secure total than the GTX 1060 and 1070 counterparts. This in flip raises the query – is there some sort of GPU driver bottleneck on the Nvidia aspect?
Background streaming issues are tougher to beat, although Kaldaien’s Batman Tweak v1.01 helps right here – its balanced and quick streaming choices assist to mitigate a few of these Batmobile stutters.
Beyond that, it is all about brute-forcing the sport with trendy PC gaming expertise. The remaining stutter points are resolved merely by uncooked energy – I examined a six-core Core i7 8700K which helped immensely, whereas a quad-core Core i7 7700K added some extra dropped frames however was nonetheless pretty stable total. Setting the 7700K to quad-core i5 and twin-core i3 configurations with diminished clocks to match today’s locked Intel processors noticed extra of these dreaded dropped frames crop up throughout Batmobile sections. Tweaking solely goes to this point – we attain the purpose the place it turns into about sheer horsepower and admittedly huge quantities of overhead.
Using a monitoring device like Riva Tuner Statistics Server, it is frankly embarrassing how little of our CPU and GPU energy is definitely utilised for almost all of gameplay. It appears to be the case that merely having the ability on faucet is required to make sure consistency. According to the RTSS overlay, AMD GPUs are utilised extra successfully than their Nvidia counterparts, recurrently hitting above 90 per cent utilisation whereas GeForce playing cards are within the 75 per cent vary. The backside line? In our testing, RX 580 and Vega 56 labored superbly at 1080p and 1440p respectively when paired with an 8700K, whereas GTX 1060 and 1070 might randomly stutter in cutscenes, whereas Batmobile sections labored nice. Arkham Knight calls for plenty of VRAM – a six gig minimal appears to be required, although round 4GB is seemingly used at 1080p (based mostly on RTSS learn-outs). Again, it is about overhead.
With a 4K60 decision/efficiency goal in thoughts, GeForce is the one sport on the town. GTX 1080 Ti is ok for probably the most half, however sits on an uncomfortable threshold the place the double-buffer v-sync can nonetheless convey body-charges crashing down in cutscenes and heavier gameplay scenes. RTX 2080 improves matter by a small however noticeable diploma, but it surely’s the highest-tier RTX 2080 Ti paired with the i7 8700K that provides us a nigh-on locked 60fps at an exquisite extremely HD pixel-rely. Based on body-fee evaluation of the preliminary 10 minutes of the sport (a much better benchmark than the ineffective in-sport device) we dropped simply single frames – 18 of them from an 18,000 pattern. To all intents and functions then, we’re there – a just about locked 4K60. It’s not fairly excellent however you’d wrestle to inform and to be frank, it appears completely wonderful.
The best ‘enhanced’ Arkham Knight expertise on consoles includes operating the prevailing code beneath increase mode on PS4 Pro, ironing out efficiency drops. It’s the identical state of affairs with Xbox One X, however decision there stays locked to 900p.
The excessive decision mixed with a superbly constant body-fee elevates Arkham Knight to the following degree – it is the closest we’ll get to a 4K remaster and it is merely lovely to behold. There’s nonetheless the sense that there is maybe an excessive amount of element in among the character rendering: moire sample aliasing nonetheless resolves on the weave of Batman’s armour, however there is no doubt – that is the elevated expertise that reveals us simply how a lot work, effort and element went into the unique paintings. But nearly as good because it appears, it additionally highlights that Arkham Knight stays a sport of its time – its approximation of bodily-based mostly rendering and the dealing with of supplies has a definite, distinctive look however the actual factor appears loads higher in additional trendy video games. Similarly, the anti-aliasing approach is sub-par and was at launch – today’s TAA would work wonders in resolving Arkham Knight’s apparent shader aliasing.
In returning to the sport and aware of the efficiency tightrope we’re strolling right here, we did not run at max settings initially. Nvidia Gameworks options had been disabled, and we dropped shadows to the traditional setting (not that it makes an enormous quantity of distinction). This helps with extra consistency with GTX 1080 Ti/RTX 2080 class hardware and it is what was used for the seize in the principle video on this web page. But simply how a lot overhead was left over on RTX 2080 Ti? Could we push additional? Nvidia’s PhysX smoke nonetheless has a crippling affect on efficiency so needed to be disabled – however paper particles, gentle shafts and enhanced rain (which appears restricted to flying droplets from the Batcape when the Dark Knight glides from a constructing) appear to work simply nice with no apparent efficiency hit, whereas shadows can return to the max setting. Playing by the primary quarter-hour of the sport – an important litmus take a look at for total efficiency – all the pieces works nice, with only one exception, one momentary glitch throughout some early gliding throughout Gotham.
It’s a reminder that regardless of how a lot we brute-power Arkham Knight to deliver this genuinely thrilling expertise, essentially we’re coping with a extremely poor PC port with an typically baffling efficiency profile. An excellent instance right here issues the curiously spectacular AMD efficiency. Directly after operating the sport on RX 580, I swapped again to GTX 1060 and re-examined. Literally the entire efficiency dips I’d seen earlier than had been abruptly gone – a state of affairs I hoped would lengthen to GTX 1080 Ti at 4K (however alas, its points remained). The inconsistency in testing is irritating however by and huge, the best way ahead is evident – we start by mitigating the streaming points with Batman Tweak v1.01 then brute-power all the pieces so far as we can take it.
The outcomes are value it although. Arkham Knight could also be three-years-previous now and the overall degree of optimisation within the PC port continues to be remarkably poor – however the sport itself is a product of genius and undoubtedly one of many standout titles of this console era. And past the visuals, the standard of the storytelling and mission design stays second to none. Rocksteady’s subsequent challenge stays unknown – and it is clearly the first focus for the studio – however we hope that the studio’s future plans additionally embrace taking care of the legacy of the distinctive Arkham Trilogy. There’s the sense that Return to Arkham was effectively-intentioned however fell brief technically and the extent to which Rocksteady signed off on it’s unclear. But what’s clear is that Arkham Knight does not want an enormous quantity of remaster work – the sport belongings maintain up, however PC clearly requires a technical revamp, whereas a point of ‘ahead compatibility’ for the consoles to come back is the least that this good title deserves.
