Never been unplayable here. Granted I went straight to 1.01, which came out right after the German release that was supposedly pretty bad in its stock form. Nowadays the performance is ok on low/medium settings with the stock game, and reports from OA will follow once I get it. Besides being familiar with the engine since OFP the key to success has been regularily vacuuming the inside of the case, especially all the fans, as those Radeons need a lot of air to stay cool.
