Steps to Reproduce

Start a session on the island.

Join the match early, and notice FPS stays stable (70–80).

Leave and rejoin the same island mid-session (after 20–50 minutes have passed).

Observe the FPS dropping instantly to 27–39 and remaining unstable.

Repeat to confirm the issue occurs consistently.

Expected Result

FPS should remain stable and consistent regardless of when the player joins the session (early or mid-session), just like before the latest update.

Observed Result

When joining mid-session, FPS drops immediately from stable levels (70–80) down to 27–39, and stays low for the rest of the match.
This issue did not exist before the most recent update and affects all devices and gameplay elements on the map.

The bug only appears in sessions with 40+ players. The session must have been running for a long duration before the joining attempt (20–50 minutes or more). The issue does not reproduce in short or low-population sessions

For accurate reproduction, please test on Middle East servers, as they consistently have the highest player counts and make the issue easier to observe.
