Arknights: Endfield should run at broadly similar frame rates on Steam Deck OLED and Steam Deck LCD. Both revisions use eight RDNA 2 graphics compute units clocked at 1.6GHz, so the OLED model is not a major GPU-performance upgrade. A Steam Deck HQ test using Proton Experimental, the Very Low preset and a 60fps cap reported mostly 60fps with occasional dips on a Deck, at 22–24W and roughly 1.5–2 hours of battery life.
The OLED is the better Endfield machine for long sessions because its 50Wh battery, 6nm APU and 90Hz HDR OLED display improve endurance and presentation. The LCD remains a sensible choice if you already own one or care primarily about frame rate per dollar: the cited hardware specifications do not show a meaningful FPS advantage for OLED.
OLED versus LCD: the short answer
| Question | Steam Deck OLED | Steam Deck LCD |
|---|---|---|
| Expected Endfield rendering performance | Broadly similar to LCD; no cited side-by-side benchmark shows a major advantage | Broadly similar to OLED |
| GPU | 8 RDNA 2 CUs at 1.6GHz | 8 RDNA 2 CUs at 1.6GHz |
| APU process | 6nm | 7nm |
| Battery capacity | 50Wh | 40Wh |
| Screen | 1280×800 HDR OLED, up to 90Hz | 1280×800 LCD, up to 60Hz |
| Best reason to choose it for Endfield | Longer runtime, higher contrast and smoother 45fps/60fps presentation | Lower-cost ownership when you already have the hardware; essentially the same GPU tier |
OLED can make a locked 45fps or 60fps output look smoother because the panel can refresh at 90Hz. It cannot generate frames that Endfield does not render. If a scene falls to 35fps, changing from LCD to OLED will not turn that scene into 60fps.

Valve lists both models with a Zen 2 CPU and eight RDNA 2 graphics compute units running at 1.6GHz. That is the part of the specification most directly connected to Endfield’s rendering rate. The OLED’s 6nm APU is more efficient than the LCD’s 7nm part, but the listed graphics configuration is the same.
#1 Best Overall
- 1TB NVMe SSD
- 1280 x 800 HDR OLED display with premium anti-glare etched glass, 7.4" Diagonal display size up to 90Hz refresh rate
- Wi-Fi 6E
- 50Whr battery; 3-12 hours of gameplay (content-dependent)
- Carrying case with removable liner
Efficiency can help the OLED sustain a workload for longer before the battery is empty. It does not, by itself, establish a higher frame-rate ceiling. There is no controlled OLED-versus-LCD Endfield benchmark covering the same patch, areas and settings, so claims of a consistent FPS lead for either model would go beyond the available evidence.
What the available Endfield test actually achieved
In a Steam Deck HQ test published January 23, 2026, Endfield was run with Proton Experimental, the Very Low graphics preset and a 60fps cap. The game mostly held 60fps, with occasional dips. The Deck drew approximately 22–24W and lasted about 1.5–2 hours.
Those are observed results from one configuration, not a guaranteed specification. The result can change with the game area, shader-cache state, background downloads, operating-system version, Proton build, display brightness and later patches. It is nevertheless a useful expectation: Very Low settings can make 60fps plausible, but demanding traversal or combat scenes may not remain perfectly locked.

Can the LCD Deck run Endfield at 60fps?
Yes, a 60fps target is reasonable at Very Low settings based on that test, but “60fps target” is not the same as a permanent 60fps lock. The LCD panel itself tops out at 60Hz, so a 60fps cap aligns with its maximum refresh rate. Watch frame-time consistency rather than relying only on the headline counter; brief dips or shader-compilation stutter can be visible even when the average is near 60.
Does OLED reach a higher frame rate?
Not on the evidence available. The 90Hz OLED panel allows a 90Hz display mode, but the same eight-CU GPU configuration means it should not be treated as a 90fps Endfield device. A 45fps cap displayed at 90Hz can provide an even cadence, and a stable 60fps output can look fluid, but the panel’s refresh ceiling is not a performance upgrade.
Battery life under Endfield’s heavy load
Endfield is a demanding game for a handheld. The cited test measured 22–24W system draw and approximately 1.5–2 hours of runtime. Because the test did not compare OLED and LCD side by side under identical conditions, do not treat those figures as a measured battery-life difference between the revisions.
The hardware still explains why OLED is the better endurance choice. It has a 50Wh battery versus 40Wh in the LCD model, and Valve states that Steam Deck OLED has “30-50% more battery life.” That statement is a product-level claim across workloads, not an Endfield-specific guarantee. The OLED’s more efficient APU and lower-power OLED panel should also reduce consumption at comparable settings.

What a lower frame cap can do
Reducing the cap to 40fps or 30fps can lower GPU work and may extend runtime, especially in areas where the Deck is otherwise rendering well above the cap. No cited controlled test quantifies the gain for Endfield, so regard the battery improvement as workload-dependent rather than a fixed number. A stable 40fps often feels preferable to an uneven 60fps on a demanding game.
Why a 90Hz setting is not free
Valve’s support guidance warns that running above a model’s display cap does not improve performance and can drain the battery faster. On OLED, select 90Hz when you specifically want a 45fps-at-90Hz cadence or a responsive desktop; do not assume 90Hz will improve a game capped at 30 or 40fps.

Display differences you will notice during Endfield
OLED model
- 7.4-inch 1280×800 HDR OLED panel.
- Refresh rate up to 90Hz.
- OLED pixels provide higher perceived contrast, especially in dark scenes.
- Lower panel power consumption contributes to the model’s endurance advantage.
LCD model
- 1280×800 LCD panel.
- Refresh rate up to 60Hz.
- A 60fps cap maps directly to the panel’s maximum refresh rate.
These differences affect image quality, motion cadence and battery use, not the number of frames the GPU can render. If you spend hours exploring Endfield’s dark interiors or prefer a smoother 45fps presentation, the OLED’s screen is a meaningful quality-of-life improvement even when FPS is unchanged.
Steam compatibility and installation status
Endfield’s PC requirements list Windows 10 or 11 64-bit, DirectX 11.1 or newer, an i5-9400F-class minimum CPU, a GTX 1060-class GPU, 16GB of RAM and 50GB of free space plus another 40GB during extraction. The Steam release supports cross-platform account synchronization.

If you are using the pre-Steam launcher route
The January 2026 hands-on test installed Endfield through a third-party route such as Epic with Heroic, NonSteamLaunchers or a directly installed launcher added to Steam. It used Proton Experimental. This is not the same as plug-and-play Verified support: you may need to add the launcher as a non-Steam game, select a Proton version, sign in, and maintain the prefix when the launcher or game updates.
Practical setup sequence
- Install the current SteamOS updates and reserve enough storage for the 50GB installation and the additional 40GB extraction requirement.
- For a native Steam install, download Endfield from its current Steam listing and let Steam create the compatibility data. If the listing remains unavailable or incompatible on your Deck, use the launcher route documented by the hands-on test.
- For a non-Steam launcher, add the launcher or game executable to Steam, open its Properties, choose Compatibility, and test Proton Experimental first.
- Launch the game once, complete account sign-in and shader processing, then restart before judging frame pacing.
- Set Very Low graphics, a 60fps cap and a 60Hz display mode as the baseline. Move to a 40fps or 30fps cap if frame pacing or battery life is more important than peak smoothness.
- Check demanding areas with the performance overlay. Compare frame time, GPU load and total power draw after shaders have finished compiling; do not infer long-term battery life from the first few minutes.
Because the current compatibility label is Unsupported, no setup path should be described as guaranteed. A Proton or game update can fix a launch problem—or introduce one—without changing the Deck hardware.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Storage: plan for the install and extraction footprint
Gryphline lists 50GB of free space plus an additional 40GB during extraction. Keep that temporary headroom available on the internal SSD or the installation target; having only 50GB free can leave the installer unable to unpack the game.
Both Deck revisions support UHS-I microSD expansion. A card is useful for capacity, especially if the internal drive is nearly full, but it does not increase the Deck’s GPU performance or solve a Proton compatibility issue. Leave additional free space for patches and shader caches rather than filling the card to its advertised capacity.
Which model should you choose?
| Your situation | Better choice | Reason |
|---|---|---|
| You already own an LCD Deck | Keep the LCD unless you want a screen or battery upgrade | Its listed GPU configuration matches OLED, and no controlled Endfield test proves an FPS gain from upgrading. |
| You are buying a Deck mainly for Endfield | OLED | Expect similar FPS, but gain the 50Wh battery, more efficient platform, HDR OLED panel and 90Hz option. |
| You play near a charger and want the lowest upgrade spend | LCD | There is no cited Endfield performance reason to pay more for OLED; compare current retail prices separately because they change. |
| You value long portable sessions | OLED | Endfield’s 22–24W observed draw makes the larger battery and efficiency especially relevant. |
| You need guaranteed, maintenance-free compatibility | Neither can be promised from the current status | SteamDB’s September 3, 2026 record lists the game as Unsupported, and launcher behavior remains update-sensitive. |
For an existing LCD owner, an OLED purchase is an endurance and display upgrade, not an Endfield FPS upgrade. For a new buyer, OLED is the more comfortable long-session platform, while the LCD can deliver the same basic Very Low-settings performance when configured correctly.
Recommended settings for a first run
- Preset: Very Low, matching the documented 60fps test.
- Frame-rate cap: Start at 60fps; use 40fps or 30fps if frame pacing is uneven or battery life matters more.
- Display mode: 60Hz for a 60fps target on either model; 90Hz on OLED only when using a compatible 45fps cadence or when you accept the extra display power.
- Compatibility: Proton Experimental for the launcher configuration tested by Steam Deck HQ.
- Monitoring: Check frame time and power draw in busy areas after shader compilation, not just in menus.
Bottom line
Endfield does not currently justify buying an OLED for higher frame rates. The OLED and LCD share the same listed eight-CU, 1.6GHz RDNA 2 graphics configuration, and the available test reached mostly 60fps on Very Low settings with occasional dips. Choose OLED for its 50Wh battery, more efficient APU, HDR 90Hz display and better long-session experience; keep or buy an LCD when value and existing ownership matter more. Whichever model you use, reserve 90GB for installation and extraction, start with Proton Experimental and Very Low settings, and treat Steam Deck compatibility as changeable while the game remains labeled Unsupported in the cited SteamDB record.
