It's only recently i've been having this problem but it seems even on instant action whenever a borg ship finishes being built or is blown up my framerate plummets.
Has there been any other instances where this has happenned?
I know they have a reputation for being laggy but i've played loads of games before and even if it did lag it was never to the severity which it is now. If it helps it all started when i played borg with 0.05 build timer on because i felt the need to build lots of cubes etc.
