Settings and notices below were checked on November 6, 2026 against Gryphline’s official announcements and NVIDIA’s driver release notes. Each notice is dated, and an older notice is not a current recommendation. Menu names and options can change with updates, so confirm them in the game itself.

“Lag” can mean three different things in Arknights: Endfield, and each has a different cause. Work out which one you have before you change settings. This guide does not promise a fix.

• Low FPS or choppy motion: the picture is slow or uneven even when everything responds.
• Stutter: frame rate looks fine, but the game hitches or freezes briefly.
• Possible connection problems: actions that respond late, or a character that snaps back to an earlier position, can be signs of a connection issue. They do not prove by themselves that the connection to the server is slow, because other causes can look similar.

For an overview of the game, see our Arknights: Endfield guide.

Start with the requirements

Steam lists the following for PC. Both tiers list Windows 10 64-bit, DirectX 11, a broadband connection and 60 GB of storage. Gryphline’s January 2026 notice for the PC client lists its own figures, which the install guide on this site sets out separately.

Minimum

• Processor: Intel Core i5-9400F
• Memory: 16 GB RAM
• Graphics: NVIDIA GeForce GTX 1060

Recommended

• Processor: Intel Core i7-10700K
• Memory: 16 GB RAM
• Graphics: NVIDIA GeForce RTX 2060

If your PC is below the minimum, settings changes may not be enough. Meeting the listed requirements does not rule out performance problems.

Use the in-game performance indicators

Gryphline’s Official Release Preview notes (January 17, 2026) describe a preview feature in the graphics settings. It shows Device Load or Estimated GPU Memory Usage, depending on the platform. Treat the indicators as hints about which settings to lower first, not as a measurement of your frame rate.

Open the graphics options from the in-game settings. Names and available options can differ between versions and hardware, so use what your menu shows. Options that often matter:

• Graphics Quality: choose a level your system can sustain rather than the highest one.
• Resolution: lowering it reduces the load on your graphics card.
• FPS: a lower limit that your PC can hold steadily often feels smoother than a high limit it cannot hold. The same January notes say the PC version adds a 120 FPS option.
• Vertical Sync: it caps output to your display’s refresh rate.
• Shadow Quality and Special Effects Quality: common options to reduce when the load indicator is high.
• Anisotropic Sampling: Gryphline’s NVIDIA App notice, covered below, lists it among the settings to adjust for stutter.

On supported hardware, the January notes say the game offers NVIDIA DLSS Super Resolution and Frame Generation options. Change one setting at a time and play the same area again so you can see what actually changed.

Notice 1: NVIDIA App optimization (February 7, 2026)

Gryphline’s notice of February 7, 2026 says that on PCs with an NVIDIA graphics card, enabling optimization features in the NVIDIA App may cause abnormal issues such as blurry graphics and game stuttering. It applies if you turned those features on for Arknights: Endfield and you see those symptoms. If you have not, it does not concern you. The page read for this guide carries no later update or statement that the issue is resolved.

If it matches your case, the notice describes:

1. In the NVIDIA App, open the game’s program settings and use Revert to return it to the “Game isn’t optimized” state.
2. In the NVIDIA App’s settings, turn off the option that automatically optimizes newly added games and apps.
3. For blurry graphics, set Image Quality Enhancement to NVIDIA DLSS and adjust the DLSS Super Resolution mode to a level your device can handle, or switch to TAAU and adjust Render Scale.
4. For stutter, adjust Graphics Quality to a level your device can handle. For further tuning, the notice lists options such as Anisotropic Sampling, and advises avoiding DLAA because of its performance cost and choosing the Balanced mode.

Notice 2: NVIDIA driver versions (March 17, 2026)

This notice is about specific drivers, not about every NVIDIA card. Gryphline’s notice of March 17, 2026 says stutter may occur with GeForce Game Ready Driver 595.79 or 595.71, or NVIDIA Studio Driver 595.79. It says NVIDIA was treating the issue with high priority and expected to resolve it in a future driver. For players on those drivers, it described two workarounds:

• In the GRYPHLINK launcher, tick the option “Launch with DirectX 11 (use if the game encounters issues)” and click Play. The notice describes this option in GRYPHLINK. Gryphline’s Steam post says the Steam version cannot be managed through GRYPHLINK, and this guide did not check an equivalent option for the Steam or Epic versions.
• Reinstall an older driver from the Drivers tab of the NVIDIA App. The notice names no specific older version.

Later NVIDIA release notes list this issue. The release notes for driver 595.97 (March 24, 2026) list “Arknights: Endfield: stutter may be observed in some gameplay” among the open issues, with NVIDIA’s reference 5950402. The release notes for driver 596.21 (April 16, 2026) list the same item among the fixed gaming bugs. The Gryphline page read for this guide was not updated with that information.

That fix concerns the issue NVIDIA identified under that reference, not stutter in general. It does not mean every stutter in the game has been resolved, and NVIDIA’s notes do not say how many players were affected. Other causes of stutter, such as the NVIDIA App optimization above, are separate. The March workarounds belong to the affected driver versions. They are historical, not a general recommendation to launch with DirectX 11 or to roll back drivers. If you are on 596.21 or a later driver, check the release notes of your driver and Gryphline’s news page before you use them.

Network lag is a different problem

If your frame rate looks fine but actions respond late, the connection may be involved, although this does not prove it. Check your connection rather than graphics settings first. Restart your router, switch from Wi-Fi to a wired connection if you can, and pause downloads on other devices. These are general suggestions, not steps from Gryphline.

One thing to know before switching servers to try to lower latency: Gryphline’s PSN account FAQ of January 19, 2026 says account data is not shared between different servers, for example between the Americas / Europe servers and the Asia server. Switching servers can mean starting with different progress.

Loading and driver problems

These are general suggestions, not steps from Gryphline.

• Install drivers from your GPU maker and read the release notes for the version you install, since known and fixed issues for specific games are listed there.
• Keep Windows up to date, then restart before testing again.
• Check your free storage. The listed requirements differ between sources, so follow the space your installer asks for.
• If the game crashes on launch, check Gryphline’s news page for a notice that matches your symptoms instead of trying unverified fixes.

Basic checks in Windows

Close programs you do not need while playing, especially anything that records or overlays the screen, then check whether behavior changes. Do not disable your security software or any game protection to try to gain performance.

A short checklist

• Decide whether you have low FPS, stutter or possible connection problems.
• Compare your PC with the listed requirements, but remember that meeting them does not rule out problems.
• Change one graphics setting at a time and test the same area.
• If you enabled NVIDIA App optimization for the game and see blurry graphics or stutter, read the February 7, 2026 notice.
• If you use driver 595.79 or 595.71, read the March 17, 2026 notice and the dates above.
• Update your graphics driver and Windows, then restart.

What this guide does not cover

• A guaranteed fix. The notices describe causes and workarounds for specific cases, and the driver fix concerns one identified issue.
• Whether a driver newer than 596.21 behaves differently.
• Performance on consoles or phones.
• Any change after the notices of November 4, 2026.
