If characters are jittery or laggy or skipping around, this is likely a networking/bandwidth issue — something is interfering with the game’s network connection.
- Quit other network-heavy programs, or shutdown devices on your network that could be using heavy internet.
- Move closer to your wireless router to increase speed.
- If you can, go wired, and connect your computer via ethernet.
Some other thoughts:
- A low graphics framerate, or the host having a low graphics framerate, can cause network issues.
- If all players on a game are experiencing network issues, it may be that the host is having network troubles.
- So, make sure the player who is hosting is running the game at a reasonable framerate. You could try asking the host to lower their quality settings, or getting a different player to host.
