Fixed FrameRate and Frame Smoothing do not work

Hello im making a multiplayer physics based game, Smoothed framerate mode create noticeable hitching in the motion of my actors against my background (the actors are moving along a dynamic vector thats calculated per frame) Fixed framerate appears to be working fine in my editor, And is giving a perfectly smooth experience in simulated multiclient in-editor play tests. However when packaged into exe’s with a dedicated server my clients begin simulating at 240fps, quadrupling the motion of everything. I’d love to cast my vote on solving this issue.
