And even I get graphical lag from SL2, under the right circumstances. (Outside, weather, etc)

Do you have BYOND set to hardware rendering? Other than that it might be a simple issue with your connection, but I'm not sure.

Do you mean this? I just checked it on, and I'll see if it makes a difference.

I'll do the same, assuming you meant I should try playing with hardware rendering off.

Edit: I usually play with it on and have been for as long as I've been playing on byond.

As far as I know, hardware mode is much more efficient, but it can be worth trying both and seeing what effect it has.
