Digital Foundry analyzes Stellar Blade frame generation on Switch 2

Digital Foundry published its analysis on Nov. 7, 2026, finding that Stellar Blade on Nintendo Switch 2 uses DLSS upscaling and AMD FSR 3.1 frame generation by default to convert a 30 FPS base into 60 FPS output.

Stellar Blade launched on Switch 2 on Nov. 5. The Switch 2 edition includes Bayonetta outfits and all post-launch content. Shift Up is developing a sequel, Stellar Blade: Blood Rain, featuring a new pint-sized protagonist.

Switch 2 lacks official DLSS frame generation support on its Ampere-class GPU, so developers use AMD’s FSR 3.1 instead. Nvidia and AMD recommend a 40-60 FPS minimum foundation for frame generation, so a 30 FPS base on Switch 2 is unusual. Digital Foundry says Switch 2 uses frame generation in a way its creators do not recommend. Stellar Blade is one of the first games on Switch 2 to use frame generation.

Shift Up CTO Dongki Lee said at Gamescom 2026 that the team reworked and tuned FSR 3.1’s rendering pipeline and swapchain integration for Nintendo Switch 2 specifically to keep a stable 30 FPS base frame rate before frame generation. Lee described the port’s key goal as showing the fun-ness and charms of Stellar Blade in handheld mode. “Stellar Blade on Switch 2 is especially optimized for that kind of upscaling.”

Shift Up added a Frame Generation toggle to Stellar Blade on Switch 2 at release after player feedback from the demo, letting players turn frame generation on or off. Digital Foundry discovered after recording its show that the feature would become a toggle, and KitGuru reported ShiftUp announced the change on Twitter following feedback from the Stellar Blade Complete Edition demo. Ahead of the Nov. 5 launch, Shift Up revealed specs confirming AMD frame generation would hit 60 FPS.

With frame generation enabled, Switch 2 docked internal resolution is about 540p and handheld internal resolution is about 360p. With frame generation turned off, docked internal resolution is about 648p and the game runs at about 35-45 FPS. Handheld and docked performance are similar, though handheld appears muddier than docked play but remains acceptable. With frame generation off in handheld mode, VRR (variable refresh rate) helps with frame rate.

Switch 2 strips back environmental detail versus PS5, removing foliage in some areas, causing pop-in in larger areas, reducing shadow, lighting, and reflection levels, and cutting detail more aggressively in larger scale shots. In some shots, the graphical cutbacks compared to PS5 are less apparent. Digital Foundry said DLSS provides a more stable presentation on Switch 2 than on PS5. Shacknews reported that Switch 2, along with PS5 Pro, is currently the only console supporting hardware-based upscaling, and Switch 2 uses a pared-back version of Nvidia’s DLSS that runs games at lower internal resolution and upscales to higher output resolution to improve performance.

The lower the input resolution, the more an upscaler struggles to reconstruct fine details like hair and intricate outfit flourishes. If resolution is low enough and the camera moves while objects are covered and uncovered, the upscaler can become temporally unstable, making up details and producing a muddy image. Shacknews found handheld static shots stable but movement caused visible breakup, with the first cutscene’s planet surface shifting and fizzling as upscaling and interpolation struggled.

Frame generation takes one rendered frame as start point and the next as end point, then slots in an extra wholly AI-generated frame between them. The GPU must wait for the second rendered frame before displaying the AI-generated intermediate frame, making a 60 FPS-looking game respond more slowly than plain 30 FPS. Upscalers cause a minor amount of latency compared to traditional rendering, and Switch 2 has no separate chipset part solely for frame generation computation, so software-based implementations are severely pared back. Frame interpolation is AMD’s version of frame generation, PC-focused because no consoles including Switch 2 support hardware-based frame generation.

Frame generation adds processing cost to an already tight frame budget on limited hardware, and when base frame-rate suffers, drops become more obvious. Delivering locked 60 FPS depends on holding a solid internal 30 FPS first.

Digital Foundry reported that with frame generation on, the HUD and on-screen text update at 30 FPS, particle effects do not interpolate well, shadow maps interpolate oddly, rain crossfades between frames, and the protagonist’s hair breaks down especially in handheld mode. Each generated frame from a 30 FPS base remains visible around 16ms versus 8ms for a 60 FPS to 120 FPS conversion, making strobing between rendered and interpolated frames easily noticeable. Interpolated frames are easier to spot in Stellar Blade on Switch 2 than on PC, and some frame generation artefacts are intrinsic while others could be improved with content tweaks or designing a game around frame generation from the start. Digital Foundry’s capture setups exaggerate frame generation lag, so the outlet may need external monitors to capture such games.

GameSpot reported via Yahoo Tech that frame generation delays actions, causing mistimed parries and dodges and sluggish control of Eve, with chaotic fights sometimes lagging so badly inputs feel ignored. GameSpot tied the input delay to Stellar Blade’s tight combat frame windows, noting the disconnect between 60 FPS visuals and heavier 30 FPS input feel makes precise timing harder, while Digital Foundry described the mismatch between smooth looks and play feel as unsettling. The mismatch between smooth visuals and sluggish feel can be unsettling for players used to native 60 FPS. Because the game is technically rendered at 30 FPS, controls and input latency feel like 30 FPS and stutters are more noticeable with frame generation than without.

Shacknews found latency was the least noticeable drawback and could still nail parries almost at will. Turning frame generation off makes Stellar Blade run at a visually native frame rate and makes controller responsiveness feel tighter. Exploration hits and holds 60 FPS for healthy periods with frame generation on, while combat and cutscenes see dropped frames and dips into the 30s before returning to consistent 60 FPS quickly. Extended frame rate dips do not happen too often with frame generation enabled, and with frame generation turned off, the game looks basically identical to when enabled.

In handheld combat, Stellar Blade runs at low resolution and the upscaler cannot keep up, creating a blocky and pixelated mess. Eve’s hair retains all physics from other versions, flowing and bobbing as she runs. Stellar Blade is too fast for its own rendering pipeline, creating a degraded experience especially in handheld mode where the cheap LCD does it no favors. Shacknews assesses the port as novel and nominally impressive but compromised to the point that playing it seems ill-advised.

Digital Foundry described Stellar Blade as close to a worst case for 30-to-60 FPS frame generation, but said interpolation is arguably better than plain 30 FPS as long as it is optional. Frame generation is mandatory in Stellar Blade’s demo, while Dragon’s Dogma 2 lets players choose between native 30 FPS and interpolated 60 FPS modes. Slower, first-person or less chaotic games should hide frame generation artefacts better than Stellar Blade. Dragon’s Dogma 2 may give a fairer picture of frame generation viability on Switch 2 than Stellar Blade.

There seemed no realistic way to get Stellar Blade to native 60 FPS on Switch 2 hardware. Digital Foundry worries frame generation could become an industry-standard solution sacrificing crucial playability.

Dragon’s Dogma 2 from Capcom also uses DLSS plus FSR 3.1 Frame Generation to hit 60 FPS on Switch 2. Stellar Blade and Dragon’s Dogma 2: Dark Arisen use this DLSS and FSR combination on Switch 2, and more third-party developers may adopt it. Digital Foundry discussed DLSS plus FSR frame generation in its DF Direct podcast Q+A, noting mixed results for the Switch 2 demo. Digital Foundry makes a case for frame generation as viable even when boosting 30 FPS to 60 FPS.

The DLSS plus FSR combination does not feel like playing at 60 FPS and introduces issues with particles and animations rendered at 30 FPS put through frame generation. FSR Frame Generation is the version before FSR 4 switched to an AI solution. NVIDIA and AMD recommend a 40-60 FPS minimum foundation for frame generation, making the Switch 2 approach better suited to slower games like Fire Emblem Fortune’s Weave than Stellar Blade. Switch 2 hardware is not powerful enough to render 60 FPS in many games, so developers seek smoother presentation solutions, and PC modders have run DLSS Frame Generation and Multi Frame Generation on Ampere-era RTX 30 Series cards, suggesting NVIDIA could deliver a Switch 2-specific version.

Digital Foundry sees a prospect of taking Nintendo’s 60 FPS first-party games to 120 FPS with frame generation, but processing cost probably rules it out. Digital Foundry says games with less rapid movement and genres where timing matters less, such as turn-based RPGs, see fewer frame-generation drawbacks.

Community mods show DLSS frame generation can run on RTX 30-series cards with relatively poor performance, and a lighter model might be possible like DLSS’s lighter Switch 2 mode. FSR 3’s frame generation compares reasonably well, frame-rate drops matter more than upscaler choice, and Digital Foundry would be surprised if Nvidia wasn’t preparing a solution.

GameSpot stated Stellar Blade plays much better on PC or PS5 than on Switch 2, even though those platforms lack portability. On Switch 2, Stellar Blade runs surprisingly well on Nintendo’s hybrid system, and on the surface looks like a smooth port with few compromises, still offering graphical detail at lower resolution. Stellar Blade requires compromises to run smoothly on Switch 2, and the frame interpolation was implemented thoughtfully with a focus on maintaining even frame-pacing.

Stellar Blade initially released on PlayStation 5 and later PC before being confirmed for Switch 2. Stellar Blade launched on PS5 in 2024 and was considered technically impressive; the Switch 2 port releases in 2026. On PS5, Stellar Blade was probably the most graphically impressive Unreal Engine 4 game alongside the Final Fantasy 7 remake trilogy. Final Fantasy 7 Remake and Rebirth have come to Nintendo’s handheld more or less fully featured.
