UE5, Not Nintendo, Is Switch 2's Real Third-Party Wall

The Switch 2 spent its first year building a reputation as a technical miracle worker. Resident Evil Requiem runs on it. Final Fantasy 7 Rebirth runs on it. Onimusha: Way of the Sword is coming day-and-date with PS5. Capcom and Square Enix made the impossible look routine. Then Sandfall Interactive, the studio behind last year’s Game of the Year winner Clair Obscur: Expedition 33, pulled the curtain back on the part of the story Nintendo’s marketing won’t tell you: the engine that powers modern AAA games isn’t ready for the platform yet.

In an interview with Automaton, Sandfall’s team said porting Clair Obscur to Switch 2 would be a “big technical challenge.” The culprit isn’t the hardware’s raw power — it’s Unreal Engine 5. The Blueprint scripting system the studio relied on to build the game doesn’t work on Switch 2 at present, and Epic’s lighter-weight alternatives like Lumen Lite are still rolling out on Epic’s schedule, not Nintendo’s. That’s the detail handheld players should latch onto: the gatekeeper of Switch 2 third-party support isn’t the console at all. It’s Epic’s release calendar.

Epic’s Roadmap Is the Real Boss of Switch 2 Ports

Holding back a port this way is a familiar feeling for PC handheld owners — just with a different failure point. Steam Deck and ROG Ally players have watched UE5 titles ship rough for years — DragonSword: Awakening needed a single tweak just to run smoothly — with Lumen reflections chewing through battery, shader compilation stutters, open zones sagging below 30 fps. On PC handhelds, that tax is visible in the settings menu and partially fixable. On Switch 2, the problem is structural. No amount of developer sweat fixes Blueprints until Epic ships engine updates that make its own feature set work on the hardware — a dependency no optimization pass can route around.

Sandfall is exactly the kind of studio this hurts most. It doesn’t have Capcom’s port army or Square Enix’s early-access partnership; it’s a smaller team celebrating a GotY win with a port that could eat a year of engineering time before returning a single dollar. The silence around Borderlands 4 — 2K hit indefinite delay nearly a year ago and has said little since — shows the pattern isn’t isolated. The Switch 2’s third-party problem isn’t enthusiasm. It’s that the tools developers build on define the port calendar, and Epic holds that calendar.

Elden Ring’s Long Delay Is the Portability Crash Test

That makes Elden Ring: Tarnished Edition the most consequential Switch 2 release of the season. It finally lands Aug. 28 after a full-year delay — the headliner of our Switch 2 pre-order roundup — with last year’s Gamescom hands-ons reportedly raising red flags. Elden Ring was built for PS4 and Xbox One, so it should sit comfortably within Switch 2’s reach — which makes its extended development time a tell about how hard even last-generation-scale games are to port. When it drops, watch the Elden Ring: Tarnished Edition reviews for three numbers: average frame rate in the open world, battery minutes per charge, and fast-travel load times. Those three numbers will say more about the platform’s third-party future than any Direct.

For studios like Sandfall, the math is brutal and simple: wait on Epic’s roadmap, sink months into a platform whose install base is still building, and hope people buy a game they already played elsewhere a year ago. Steam Deck and Windows handhelds sidestepped all of it — Expedition 33 shipped on Steam, and portable PC players got it in year one. The Switch 2 was supposed to erase the distance between a handheld and a home console, and in 2026 it still can for the right games. Clair Obscur’s limbo is the reality check: that distance was never about silicon. It’s about who controls the engine underneath, and Switch 2 players are waiting on Epic.
