Why does lag and rubberbanding still happen? Nearly every game has some. Game’s been out nearly 4 years and the servers still suck.
What’s your connection like? Wired or WiFi? NAT Type? Upload/Download speeds? Also where in the world you are will affect how close the nearest data center is.
It’s fine in other games, Halo has always been sketchy. I see enemies teleport a few times each games. My connection is wired, NAT open, 150Mb Down, 10Mb Up, Seattle, WA.
