Arma 2 is the shiznit, and, hey: they've been releasing beta patches like twice a month at least, and each one has improved my fps by +1 at least, so judging by this I'll be up to perfectly reasonable FPSes by the time 1.06 rolls out
That said: Hey man! Always great to see an old face around. OFPEC is, well, OFPEC is hanging in there as always, no plans on going anywhere I think. The community is actually larger than it was before, at least over at the BIS forums, lots of activity, addons and missions. The MP scene is what dominates, ever since ArmA and JIP, but it seems that Arma 2 has somehow avoided the Evolution/Domination pairing (now it's just Domination. And Warfare. I think?). Not that I'm into all of that anyway.
Anyway, if you have a semi-decent, dual-core rig with a nice(r) graphics card, you can totally run Arma 2. It's fun! You should try it. And come baaaack. Hear the siren's call...come baaaaaack...much more fun to run around virtually than in real life, don't you know
Wolfrug out.
