did u test SE multiplayer? how is the performance if u play on different planets?

I think it really depends on how the game is played. There are also mod considerations. Things like AAI Vehicles or AAI Structures can take a toll if even 1 force is going overkill even just on a LAN session. The game having too many entities can be a problem as well. There are things you can do to try and balance all that I think, and it really boils down to the server admin to diagnose issues and enforce reasonable limitations on the culprits.

I mean SE is only playable if all player don't check any other surfaces. That's why asked. Else u get a lag fest. I was wondering if the same is still true if ur not on the same force.
