Find out which server you are on before anything else. Endfield has only two — Americas / Europe and Asia — and that choice sets the floor your ping can never go below.
On PC and mobile the server selection screen shows each server's ping. Take the lower number. You get this choice once, at account creation, and there is no switching afterwards.
On PS5 you do not get a choice at all. The server is assigned from your PSN account's region, and manual selection is not supported. A PSN account registered in the wrong region is the whole explanation for some players' ping.
Nothing transfers between servers. Progress on Americas / Europe is not shared with Asia, so 'just reroll on the closer server' costs you the account.
Separate high ping from stutter. Frame drops, menu lag and hitching after a driver update are performance problems — a different fault with different fixes, and no network change will touch them.
Go wired and clear the line before blaming the game. Endfield syncs account and combat state continuously, so jitter hurts it more than raw bandwidth does.

Lag or disconnects on launch day?

Half the launch-week "server errors" we trace are routing problems between you and the game servers, not the servers themselves. A game booster reroutes that path. GearUP is the one we point people to: it supports most new releases within a day of launch.

Most Endfield ping advice starts with your router. That is the wrong end. The single biggest factor in your ping is a choice you made in the first sixty seconds of the game, on a screen most players clicked through, and it cannot be undone.

There are only two servers, and you pick once

Endfield runs Americas / Europe and Asia. That is the whole list.

On PC and mobile, the server selection screen shows you the available servers with their current ping next to each one, and the advice is the obvious one: take the lower number. What almost nobody registers at that moment is that the choice is permanent. There is currently no way to switch servers in Endfield — once you start on one, that is where the account lives.

And the accounts really are separate. From Gryphline’s own Help Center:

Account data is not shared between different servers. For example, progress on the Americas / Europe servers is not shared with the Asia server.

So if you are in, say, Southeast Asia and picked Americas / Europe on launch day because a friend did, your ping floor is now an ocean wide and the only way out is a new account. Worth knowing before you spend: blueprint codes are server-exclusive too, so a second account does not inherit your imports either.

The one thing that is shared: within the same server, your data works across platforms.

Within the same server, account data is shared across different platforms, including PC, Android, iOS, and PS5™.

On PS5 you never got a choice

This is the part that explains a whole category of complaints, and it is stated plainly in the official FAQ:

The PS5™ version of Arknights: Endfield supports the Americas / Europe server and the Asia server. When you log in on PS5™, the game server will be automatically assigned based on the region of your PSN account. Manual server selection is not currently supported.

Read that again if you play on PS5 with high ping. Your server was chosen by your PSN account region, not by where you are sitting. Plenty of people hold a US PSN account for store reasons while living in Asia, or a Japanese one for the same reason while living in Europe. On PC that mismatch is visible and avoidable; on PS5 it is invisible and locked.

There is no in-game setting to fix this. The only levers are a PSN account in the right region — which has its own consequences for your purchases and library — or reducing the damage on the route you are stuck with.

What still moves the number, and what doesn’t

Once the server is settled, your ping is three things stacked on top of each other. Only two of them are yours.

What it is	Can you change it?
Physical distance to the server you are bound to	No. This is the floor, and it is set by the choice above.
The route your traffic takes to get there — which networks it crosses and how directly	Sometimes. Bad ISP routing can add far more than the distance itself, and that part is not fixed.
Your own line — Wi-Fi interference, background traffic, a congested router	Yes, and this is the cheapest to test.

The order matters. If you are on the Asia server from Asia and still seeing 200 ms, that is not distance — something in the route or on your line is adding it, and it is worth chasing. If you are on Americas / Europe from Asia, a large number is simply the geography of the choice, and no amount of router fiddling will bring it to where a local player sits.

For the third row, the quick version: use a cable if you can, and clear the line before you play. Endfield keeps your account and combat state synced continuously rather than saving locally and uploading later, which means it is far more sensitive to jitter and packet loss than to your download speed. A connection that streams video perfectly can still feel broken in combat. Pause downloads, cloud backup and anyone else’s 4K stream, then re-check.

High ping and stutter are not the same fault

This is where most of the wasted effort goes. Two very different problems get called “lag”:

High ping / rubberbanding / delayed hits — the server and your client disagree about where things are. Network.
Frame drops, hitching, menu lag, stutter right after a driver update — your machine is not producing frames fast enough. Not network, and no routing change will touch it.

If your frame counter dips at the same moment it feels bad, you are looking at the second one. Check the PC requirements and settings instead, and roll back a driver if the timing lines up with an update. Treating a GPU problem as a network problem is the most common dead end in this whole category.

The official steps, for completeness

Gryphline’s Help Center answer for login, stuttering and crash issues is short and worth running before you file a ticket:

Check that your PC meets the system requirements.
Make sure you are on a stable network, and check server status.
Force quit the game, restart, and log in again.
Restart the device.
Log in on a different platform or device, then switch back.
If none of that works, re-download and reinstall.

If you get past all of it and the problem persists, contact support through the Help Center rather than waiting it out — they can see things about your account that you cannot.

The two-server list, the PS5 automatic assignment by PSN region, the absence of manual server selection, the isolation of account data between servers and the cross-platform sharing within one server are all quoted from the official Arknights: Endfield Help Center, which also supplies the login/stuttering/crash troubleshooting list. The server selection screen showing per-server ping, and the fact that progress cannot be transferred between servers, are documented in GameWith’s server guide. Gryphline publishes no public table of Endfield’s numbered network error codes; where you see one, it is a community reconstruction rather than an official reference.
