Co-op & Server

Latency and lag check

Use this when the session is technically up, but the play still feels delayed or messy.

Lag often gets blamed on the game before the setup is even checked. This page keeps the problem grounded in the shared session, not in guesswork.

Current watch

Watch whether the issue survives a clean relaunch, a version match, and one normal shared-session test.

What to check

Keep the retest short and tied to one real failure.

Why this hub exists

The hub works best when it explains the maintenance reason before it starts routing you onward.

FAQ

Short answers before you open another tab.

Do I always need a special lag page?

No. Start by proving the baseline.

What if only one player feels the delay?

Then the issue may be setup, host, or connection-specific.
