Framerate issues when Multiplayer Enabled - Bedrock 1.16 Beta

Noticed significant drop in framerate performance after initial install of the beta (compared with standard bedrock).  Normal frames per second was around 30-45 prior to beta.  Now down to 16-19. 

Disabled Multiplayer on a beta world (preventing it from showing up on Friends list), and found that frame rate had returned to 44fps.
