huge delay between my 2 characters, causing us to spread out. Is there any way to fix this?
It depends what's causing it

Are you CPU-bound (under Windows, you can use the task manager to get an indication of that)?

Have you at least set the "maxfpsbk" to a low but tolerable value so as not to strain your system unnecessarily?

If you're not sure what that means, you'll be able to find out more with a quick search for that keyword.
