I'm so happy for Bohemia, I think they've finally made the game we've all dreamed of playing since Op Flashpoint.
I'm not surely it's entirely Alpha to be honest, I've done a bitta QA and this is what some people would pass as beta. I've had a few OOM crashes and it's smashing my CPU to pieces but I reckon once I give my radiators a clean and OC my CPU I might hit 40fps which would be enough for now.
It's typically ARMA though, you can tweak the graphics settings all you like, it all comes down to CPU, RAM and having a decent motherboard with the power to keep it all stable. It's a machine killer and an obvious candidate for benchmarking.
Wasteland was first out of the gate but I wouldn't be surprised to see a community build of DayZ (and the rest) find it's way onto the pre-release. Mod's will encourage the transition and one day I'll just find myself not playing ARMA 2 any more.
ARMA 3 can come out whenever it likes now, it's like when you really want to see a girl naked, you don't care if it progresses into a relationship, you just want to see nipples.
