I’m not sure if this is the right section (I don’t have access to bug reports and I’m unsure whether this is a bug), but enabling streaming in my game considerably increases the average ping.
When streaming is disabled, the ping is great, however, when streaming is enabled and a decent number of players are playing, the ping increases significantly.
Does your map use terrain? If so, this is normal. Your players most likely have a limited download bandwidth and when downloading the map and unloading it, the players will have an increase in ping due to the network traffic. To speed this up with streaming, you must make the StreamOutBehavior set to LowMemory so that content is stored in memory and is not constantly downloading.
It’s currently set to LowMemory. I’ve experimented with both settings, it ends up with a similar result. It could just be terrain in general though which kind of sucks.
