[MCM-863] Performance degrades significantly in areas with high number of player entities

Partner Rank: (On a scale of 1 to 4 where 1 is the most important, how would you rank the importance of this bug?)

1. - Critical

Partner Team Reporting:

The Hive

Verification builds:

R14 release (1.13.25.0)

Summary:

Performance degrades significantly in areas with high number of player entities.

Impact:

Players on weaker devices, including Xbox, are less likely to spend time and money on servers. This results in lower CCU, DAU, MAU and revenue.

Repro Steps:

Join a Featured Servers with high players in the hub areas, for example, The Hive
Monitor the FPS and "laggy" feeling
Compare to R12

Observed Results:

The FPS is significantly lower than R12 in areas with player entities.

Expected Results:

The FPS should be close to R12

Screenshots/Videos attached:

Yes. FPS is hard to show properly in a video (as even non-laggy XBOX recording may look laggy), so following repro steps on consumer hardware is advised.

Regression Builds:
Any R12

Notes:

See thread in #servers_all_chat for multi server verification.

Servers use fake-player entities for anything with a custom skin. Because of this, it's not rare to have 80 or more player entities at spawn. However, this performed fine in R12.
