Hello yWhite,
unfortunately you have not provided enough information for people to help in any real meaningful way.

Here is a list for ya to answer and use in future.

• Are you hosting the game yourself, or is it a 3rd party dedicated server?
  
• Vulkan or DX?
  
• PC specs if you are indeed hosting it yourself, or of the host.
  
• Are you and your friend using mods? which ones?

Good luck, i hope some one will be able to help.
