MP woes!

[SEE]

Cant remember whether it was Leadfarm or Kampverbrand hosting current beta patch version but, whichever it was, there were only a couple of players.

My first time, selected Army, airfield, plane, etc and hit 'create' and immediately on spawning (tried several times) - 'kaboomb' I blew up ....

Tried one of the others (from above) and spawned on the deck OK. I got close to another player and fps went down to zilch. (there was only one other player ac in server and my rig is fine in SP)

Am I doing something wrong or is MP glitched for me to keep blowing up each time I spawn and experiencing massive drop in fps?

I assume that my video settings are used when joining servers?
