Performance and Network Troubleshooting

Quick symptom split

Low local frame rate

Adjust Render Scale, then Quality

Players jittering

Likely network issue

Voices dropping

Likely network issue

World geometry missing

Update graphics drivers

Host running poorly

Can affect the network session

Official low-frame-rate order

• Lower Render Scale first.
• If performance is still too low, reduce the overall Quality setting.
• Once frame rate is stable, raise Render Scale gradually until image clarity and performance are balanced.

Network checklist

• Close downloads, streams, cloud sync, and other bandwidth-heavy programs on the host and affected guest.
• Move closer to the router when using Wi-Fi.
• Use wired Ethernet where practical.
• Retest with the group in the same open area so intended voice distance and walls are not confused with a connection fault.
• Record which players jitter or lose voice and whether the problem follows one host.

Check the host's frame rate

The official FAQ warns that low frame rate on the host can cause network issues for the session. If several guests have problems at once, check the host's performance before troubleshooting every guest independently.

• Apply the Render Scale and Quality sequence on the host.
• Stop high-load background programs on the host machine.
• Recreate the session only after the host is stable, then share the newly generated Join Code.

Characters jitter or voices cut out

The FAQ treats these as common signs of network trouble. First rule out intended spatial effects by regrouping in the same open space; then work through bandwidth, Wi-Fi distance, wired connection, and host performance.

Ocean or other world geometry is missing

The official FAQ uses a missing ocean as an example of a graphics-driver problem. Update the GPU driver from the hardware vendor, restart the system, and retest before treating the world save as damaged.

• Record the GPU model, driver version, platform, and game version.
• Capture a screenshot of the missing geometry.
• Do not delete or replace the host save as the first response to a rendering symptom.
