We’re a MOBA set up using Gamelift and AWS. Everything up until about a month ago was fine, but now, we’re getting horrendous lag that sometimes goes away, most of the times doesn’t, shortly into our game. We’ve tried different champion setups, no items, not doing certain interactions, etc. and we can’t seem to nail it down. Our test today it happened every single game a few minutes in, while last week, it happened every other game or so. We’re morons when it comes to stuff like network profiler and all we’ve found in the game log is this:
[2020.03.11-19.49.10:636]LogCharacterMovement: Warning: GetSimulationTimeStep() - Max iterations 8 hit while remaining time 0.099570 > MaxSimulationTimeStep (0.050) for ‘Ink_ChampionBP_C_12’, movement ‘Walking’

So our guess is we’re sending too much to the Network and it’s stopped receiving, but how do we find out why? Here’s a google drive of our Net Profiler if anyone can take a look, but we’re also open to other ideas on how to debug this and figure out exactly what is going on.

Any ideas? Will literally pay someone if it means figuring this out.
