I bought almost all the modules up to the M2000, but uninstalled DCS World after another useless update about half a year ago gave me erratic random pauses during gameplay for no reason at all, after it was running smooth like butter before (and I'm not talking about the update that upped the default settings, but one sometime after that).
I'm now flying Flaming Cliffs 2 and A-10C Warthog stand alone. Saves me lots of HD space, too. ED can go and **** themselves.
