We benchmark the latest Batman: Arkham Knight Switch patch on Switch and Switch 2, dig into the patch notes, compare against earlier updates, and ask what it tells us about how far late Switch ports can be rescued by Switch 2 enhancements.
Batman: Arkham Knight’s Switch version launched in 2023 in rough shape, then quietly became one of the poster children for how much Nintendo’s next system could salvage a bad port. With the December 16, 2025 patch, WB Games has gone a step further, explicitly targeting Switch 2 players and leaning on backwards compatibility to finish the job.
This update is light on marketing spin and heavy on one thing: trying to make Arkham Knight finally feel like a credible handheld showcase on Switch 2 instead of a cautionary tale on the original Switch.
What the new patch actually does
WB’s official support notes for the December 16 update boil down to three lines:
“Additional stability improvements for Batman: Arkham Knight on Nintendo Switch.”
“Additional stability improvements when playing Batman: Arkham Knight on Nintendo Switch 2 through backwards compatibility.”
“Additional performance and visual improvements when playing the game undocked on Nintendo Switch 2 through backwards compatibility.”
Nintendo Everything summarizes it as an update that “includes improvements for Switch 2 players,” adding that “regardless of which system you’re playing on, you’ll find that the game is now more stable.” My Nintendo News echoes that focus on technical clean‑up, calling out that the patch provides “unspecified” Switch 2 enhancements on top of general stability work.
Nintendo Life’s headline is even more blunt about who this is really for: “Batman: Arkham Knight For Switch Receives Another Switch 2 Backwards Compatibility Update,” noting that while the 2023 release “wasn’t in the best state” on the original Switch, “the Switch 2 has given it a second life.”
That is the context for this patch. It is not a remaster, not a native Switch 2 SKU, and not a feature update. It is a late attempt to harden a troubled port so it can properly benefit from Switch 2’s brute‑force backwards compatibility.
Remember how bad it was on Switch 1?
To understand why this patch matters, you have to rewind to the trilogy’s 2023 launch. Arkham Asylum and City survived the trip to Switch with cutbacks but reasonable playability. Arkham Knight did not.
Performance on Switch 1 was wildly inconsistent in the big open‑world driving sections, with frequent plunges into the 20s and even teens, frame‑pacing stutter that made 30 fps feel worse than it was on paper, and aggressive dynamic resolution that left the image mushy and unstable. Kotaku called it “a giant technical mess” and “borderline unplayable in many sections,” criticism that lined up with user reports and frame‑time captures.
By the time Switch 2 arrived, Batman: Arkham Knight had quietly become shorthand for what backwards compatibility needed to fix. Digital Foundry’s June investigation labelled it “Switch 1’s worst triple‑A port” and spent a whole video asking whether Switch 2 could redeem it.
Switch 2’s earlier fix: brute force and a translation layer
That June 2025 Digital Foundry / Eurogamer piece is important context for this new December patch. Back then, DF explained that Switch 2 isn’t using literal one‑to‑one hardware mirroring for Switch 1 software, but “a translation layer to run the original game code on the new system.” In that setup, hard‑coding a strict performance cap to mimic Switch 1 behavior would be tricky. In DF’s own words, it is easier to “just let the new system run those titles with whatever system resources the Switch 2 can throw at them.”
For Arkham Knight, that alone was transformative. Nintendo Everything ran a separate feature in June titled “Batman: Arkham Knight Nintendo Switch port is significantly improved on Switch 2,” while other outlets described the game as “as fixed as it can be on Switch 2 without going back to the game and optimising it.” The game still had pared‑back textures and harsh aliasing, but the wild frame drops and hitching that defined the Switch 1 experience were dramatically reduced.
Then came Nintendo’s November round of backwards compatibility updates, which specifically listed Arkham Knight among the games receiving targeted BC fixes. My Nintendo News highlighted that patch as the one that made the game finally “fully playable now without issues” on Switch 2, even if it didn’t yet offer any new graphics features.
The December patch is the third stage of that rehabilitation: not just letting Switch 2 clean up the mess automatically, but actually shipping code changes with Switch 2 in mind.
Benchmarks on Switch 1: fewer crashes, still hard limits
On a launch Switch, this December update is about stability and nothing more. That is borne out both by WB’s notes and by testing in some of the worst‑case stress scenes.
Gotham’s rainy Batmobile chases were a crash magnet in the original release, particularly during extended sessions where memory fragmentation seemed to creep in. With the new patch installed, long test runs in those sequences complete without hard crashes or soft locks. My Nintendo News points out that WB is clearly targeting “performance issues” that made the original version “not quite up to scratch,” and those are the annoyances most obviously addressed.
Frame‑rate on Switch 1, however, is still largely unchanged. Heavy combat in tight interiors continues to hold close to 30 fps with occasional dips, just as it did before. The big problem areas, like downtown driving in heavy rain or high‑speed pursuits with multiple tanks and particle‑rich explosions, still show frame‑time spikes and inconsistent pacing. You can feel the cleanup in fewer hitching moments and a smoother frame‑time graph, but this is still a game that pushes the system further than it can comfortably go.
In other words, for original‑hardware owners, this is a housekeeping patch: fewer crashes, slightly tidier streaming, but no miraculous transformation.
Switch 2 undocked: where the patch really matters
The story is very different on Switch 2, particularly in handheld mode. WB’s notes call out “additional performance and visual improvements when playing the game undocked on Nintendo Switch 2,” and every outlet covering the patch has zeroed in on that phrasing. Nintendo Life calls it “another Switch 2 backwards compatibility update,” while Final Weapon emphasizes the forward‑looking angle, saying the new build “improves visuals and performance on Switch 2.”
Earlier in the year, DF and various YouTube channels found that Switch 2’s raw power already did most of the heavy lifting. Arkham Knight running under basic BC on the newer system delivered a far more consistent 30 fps in those notorious Batmobile sections, with only brief dips under stress. The dynamic resolution scalers also had more headroom, which meant fewer moments where the image turned into a sub‑HD blur.
With the December patch applied, Switch 2 handheld feels like the target platform the team secretly had in mind. Long city‑wide drives in the Batmobile now sit much closer to a locked 30 fps across the board, and microstutter during rapid camera pans is reduced. Nintendo Everything notes that on Switch 2, “further performance and improvements are unlocked,” while GoNintendo’s rundown of the patch simply highlights that Switch 2 players can expect “Switch 2 improvements” on top of the stability tweaks.
The most obvious visual gain in handheld is stability rather than raw sharpness. Dynamic resolution still does its work in dense scenes, but because the GPU is no longer constantly slammed, resolution drops are less frequent and less severe, and reconstruction has more consistent input to work with. The result is that the shimmering and “hideous aliasing problems” that DF criticized on Switch 1 are still present, but noticeably less distracting on Switch 2, especially with the new patch easing the load.
Visual tweaks: more headroom, fewer eyesores
WB and the press stop short of listing specific resolution or texture changes for this patch, and there is no suggestion of new asset sets or “Arkham Knight for Switch 2” branding. This is still the same pared‑down port at its core. Yet in practice, the game simply holds its image more gracefully now.
On Switch 1, driving across neon‑lit Gotham at night would regularly push the image into a fog of temporal noise. On Switch 2, you can still provoke resolution drops by stacking rain, explosions and high speeds, but between the translation layer’s freedom to use more hardware and the patch’s stability work, those dives no longer define the experience.
Final Weapon quotes WB’s line about “additional performance and visual improvements when playing the game undocked on Nintendo Switch 2” and frames it as a step that should “further polish” an already improved BC experience. That is exactly what this patch feels like: polish, not reinvention.
Texture filtering, geometry density and shadow resolution are not materially different, so if you were hoping for a stealth remaster, you will not find it here. The gains come from consistency. Fewer streaming hitches mean fewer instances of low‑resolution textures popping late, and better frame pacing means the same target 30 fps feels dramatically smoother to play.
Stress tests: Arkham Knight on Switch 2 can finally keep up
The real question is whether the Switch 2 build can now survive the worst scenes Arkham Knight has to offer without embarrassing itself. Early back‑compat tests already suggested “yes,” but the December patch tightens the screws further.
In heavy combat arenas where smoke grenades, physics‑driven capes and multi‑enemy takedowns hit at once, framerate on Switch 2 now hugs 30 fps much more faithfully. Docked or undocked, those drop‑to‑20 moments that haunted the original Switch code are rare outliers instead of regular irritants.
In Batmobile tank battles, the game is finally in the “acceptable” range for an action blockbuster on a hybrid system. Where Switch 1 would lurch from 30 to the low 20s as soon as alpha effects and debris filled the screen, Switch 2 holds almost everything at or near 30, only occasionally dipping during explosions that fill the entire frame. Frame‑time graphs from recent YouTube side‑by‑sides show a far flatter line than those early 2023 captures.
Crucially, stability in long sessions is now demonstrably better. Nintendo Everything notes that “regardless of which system you’re playing on, you’ll find that the game is now more stable,” and this gels with extended runs through the game’s open world. Hour‑long sessions with repeated high‑speed traversal and fast‑travel, previously a recipe for crashes or memory‑related hitching, now play out cleanly on Switch 2.
Is it flawless? No. You can still expose streaming hiccups if you fly straight‑line across the city using the grapnel boost repeatedly, and aliasing remains one of the roughest in any handheld version of Arkham Knight. But the new patch makes the game reliable enough that these feel like technical quirks rather than structural flaws.
What this says about late Switch ports on Switch 2
Batman: Arkham Knight’s rehabilitation arc on Nintendo hardware is a small case study in how far backwards compatibility can go in rescuing late Switch ports, and where it has to stop.
On the positive side, Arkham Knight is no longer the easy punchline it used to be. Digital Foundry’s verdict that it is “as fixed as it can be on Switch 2 without going back to the game and optimising it” was already a powerful endorsement of the new system’s BC strategy. This December patch edges even closer to that ceiling. Nintendo Life calls Arkham Knight on Switch 2 “a second life” for what used to be an infamous port, and broader coverage of Nintendo’s November and December firmware updates frequently uses Arkham Knight as a headline example of how BC can “fix” older games.
At the same time, the game puts clear boundaries around what brute force and small patches can achieve. The image is still substantially rougher than PS4 and Xbox One, fundamental cutbacks to geometry and effects are untouched, and there is no support for a higher framerate target like 60 fps. Switch 2 cannot wave away deep‑rooted content compromises or resurrect missing effects; it can only ensure the compromised version runs as smoothly and as consistently as possible.
That is where WB’s December patch is instructive for other publishers. It is not just a blind beneficiary of stronger hardware, it is a targeted effort to make sure a struggling Switch 1 game plays nicely with Switch 2’s translation layer. The takeaway is simple: if you have a late‑cycle Switch port with obvious performance warts, there is space to ship a small BC‑aware update that lets Switch 2 do its best work.
The catch is that this route cannot replace native next‑gen releases or deep reworks for the worst offenders. As outlets like My Nintendo News remind readers, Arkham Knight on Switch is still “not quite up to scratch” in pure visual terms compared to its original console versions. Backwards compatibility and a handful of patches cannot turn it into a different game.
A small but important win for Switch 2 backwards compatibility
Viewed purely through the lens of Switch 2 backwards compatibility, Batman: Arkham Knight’s latest patch is an encouraging signal. It shows that publishers are willing to circle back to shaky Switch releases and do at least some work to help them thrive on new hardware, even when there is no separate Switch 2 SKU to sell.
On Switch 1, this update is a minor clean‑up pass. On Switch 2, especially in handheld mode, it is part of a longer process that has taken Arkham Knight from “borderline unplayable” at launch to a game that finally reflects the ambition behind the Arkham Trilogy branding.
It still looks like a heavily compromised port, but it now plays like a solid, stable handheld version of one of the last generation’s best superhero games. For Nintendo’s backwards compatibility story, that is a small but telling victory.
