TL;DR
A new Kingdom Hearts 3 graphics comparison video benchmarks the Nintendo Switch 2, PS5, and Steam Deck, revealing that the Switch 2 runs the game at 1080p/30fps docked with noticeable texture and lighting downgrades versus the PS5’s 4K/60fps performance mode. This matters because it’s the first direct, independent visual test of a major third‑party title on the Switch 2 hardware, offering a concrete look at how Nintendo’s new console stacks up against current‑gen competitors.
What Happened
On June 10, 2026, the tech analysis channel Nintendoeverything.com published a side‑by‑side graphics comparison video for Kingdom Hearts 3 on three platforms: Nintendo Switch 2, PlayStation 5, and Steam Deck. The video shows the Switch 2 version running at 1080p resolution with a 30fps cap in docked mode, while the PS5 delivers 4K resolution at 60fps (with dynamic resolution scaling) and the Steam Deck achieves a 720p/30fps handheld profile with medium‑to‑low settings.
Key Facts
- The Nintendo Switch 2 version of Kingdom Hearts 3 runs at 1080p docked and 720p handheld, both locked to 30 frames per second, with no 60fps option available.
- The PlayStation 5 version supports two modes: a 4K/30fps quality mode with ray‑tracing effects, and a dynamic 1440p–4K/60fps performance mode that drops some ambient occlusion and shadow detail.
- The Steam Deck runs Kingdom Hearts 3 at 720p/30fps on Medium settings, with occasional dips to 25–28fps in crowded combat sequences.
- The Switch 2 version uses lower‑resolution textures on character models and environments compared to the PS5, particularly noticeable on Sora’s keyblade reflections and world geometry.
- Load times on the Switch 2 average 12–15 seconds for fast travel, versus 4–6 seconds on the PS5 (using its internal SSD) and 8–10 seconds on the Steam Deck (NVMe SSD).
- The comparison video was captured using Switch 2 retail hardware and PS5/Steam Deck units running the latest system software as of June 2026.
- Square Enix has not officially commented on the Switch 2 port’s technical specifications, but the video confirms it is a native port rather than a cloud‑streamed version.
Breaking It Down
The most revealing aspect of this comparison is not the raw resolution or framerate numbers, but the texture and lighting downgrades on the Switch 2. Kingdom Hearts 3 is a UE4 title that already struggled on the original Switch’s hardware — thus requiring a cloud version. The Switch 2’s custom NVIDIA T239 SoC (based on Ampere architecture) delivers enough GPU compute to run the game natively, but the memory bandwidth appears to be the primary bottleneck.
The Switch 2’s 68.3GB/s memory bandwidth (LPDDR5 at 5,500 MT/s) is roughly one‑third of the PS5’s 448GB/s (GDDR6 at 14 Gbps), explaining why texture resolution and shadow quality are aggressively reduced.
This bandwidth gap forces developers to make trade‑offs that go beyond simple resolution scaling. The video shows that the Switch 2 version uses smaller texture mipmaps on key assets like Sora’s costume details and enemy models, and dynamic shadows are rendered at lower resolution with softer edges. The PS5’s ray‑traced reflections on watery surfaces in the Olympus Coliseum world are completely absent on the Switch 2, replaced by screen‑space reflections that lose detail at glancing angles.
The 30fps lock on the Switch 2 is also telling. Kingdom Hearts 3’s combat system relies on fast camera movement and particle‑heavy magic effects. At 30fps, the game remains playable but feels noticeably less responsive than the 60fps PS5 mode, particularly during flowmotion attacks and Attraction Flow sequences where the camera spins rapidly. The Steam Deck, despite its lower base resolution, benefits from variable refresh rate (VRR) support on its 60Hz display, smoothing out framerate dips in a way the Switch 2’s fixed 60Hz panel cannot.
What Comes Next
- Square Enix will likely release a day‑one patch for the Switch 2 version addressing load time optimizations and potential framerate stability improvements — expect this within two weeks of launch (estimated July 2026).
- Digital Foundry and GameSpot’s tech team are expected to publish their own deep‑dive analyses of the Switch 2 port, including frame‑time graphs and pixel‑count tests, within the next 7–10 days.
- Nintendo may issue a statement clarifying whether future Switch 2 ports of UE4/UE5 titles will target 30fps as a baseline, or if performance modes are being explored for less demanding games.
- The Kingdom Hearts series’ remaining titles (Kingdom Hearts 1.5 + 2.5 Remix, Kingdom Hearts 3 + Re Mind DLC) are widely expected to receive native Switch 2 ports by Q4 2026, based on datamined references in the current build.
The Bigger Picture
This comparison underscores two broader trends in the console market. First, the generational gap in memory bandwidth is becoming the defining technical limitation for handheld‑hybrid consoles. The Switch 2’s LPDDR5 memory, while efficient, cannot match the bandwidth of dedicated GDDR6 on stationary consoles, forcing developers to make visible compromises even on relatively older titles like Kingdom Hearts 3 (released 2019). Second, the rise of the Steam Deck has created a new benchmark for portable gaming performance — the Deck’s 720p/30fps profile, while not flawless, demonstrates that x86 handhelds can run AAA titles at playable framerates, putting pressure on Nintendo to either optimize aggressively or accept lower visual fidelity.
The cloud‑vs‑native debate that dominated the original Switch’s Kingdom Hearts 3 release is now settled: Nintendo has chosen native ports, but the cost is clear in the comparison video. For players who value portability above all else, the Switch 2 version is adequate; for those who prioritize visual fidelity and smooth performance, the PS5 remains the definitive way to play.
Key Takeaways
- [Switch 2 Performance Cap]: Kingdom Hearts 3 runs at 1080p/30fps docked on Switch 2, with no 60fps option — a significant downgrade from PS5’s 4K/60fps performance mode.
- [Memory Bandwidth Bottleneck]: The Switch 2’s 68.3GB/s memory bandwidth is roughly one‑third of the PS5’s 448GB/s, forcing lower‑resolution textures and simplified lighting.
- [Native Port Confirmed]: The Switch 2 version is a native port, not cloud‑streamed, meaning all rendering is done on the handheld hardware — a first for Kingdom Hearts on a Nintendo console.
- [Broader Implication]: The comparison sets expectations for future Switch 2 ports of UE4/UE5 titles: expect 30fps caps and medium‑to‑low visual settings as the standard.
