Ping spikes that causes rubber banding after first round of gameplay

Summary

Ping spikes after first round of gameplay:

Hi!

Our team has run into an issue involving “ping spiking” when testing our game on a published code. What essentially happens is that we go through playing the first round (our game is round based) and everything is fine. As soon as we start playing the second round we start getting ping spikes from 20-120 ping for the first 30 seconds of gameplay. After that it seemingly stabilizes for the remaining duration of the round. The symptom of this is rubber banding and choppy player movement.

The issue is consistent every time and happens at the exact same phase of the round. At the start of our game we are loading in a lot of things and we do some heavy calculations but this is not where the ping starts spiking. It is only way after when the initial loading of everything has finished and the players are skydiving down to our level that the pink spiking starts.

I’ve looked through some code to see what is happening at that exact point of gameplay and there isn’t much at all happening. What we do just before that point is that we teleport all players in the game through a teleporter device. Just after everyone has teleported, the ping spiking starts.

I’ve looked through other code to see if we have any heavy loops running in the background. We have one loop that is quite lightweight and we already tried disabling it entirely without getting any different results.

I’ve tried to look around for others with the same or similar issues but haven’t found any solutions out of these searches.

I’m a bit lost on where to go from here. I’ve tried everything that comes to mind and haven’t been able to fix it. It’s not entirely game-breaking but is definitely of annoyance.

I apologize in advance but I cannot provide a code at this moment.

If you have any ideas or need me to clarify anything, feel free to reach out!

Thanks in advance!
