First off, It's been a long time since I posted here, loved OFP. The guys at Bohemia Interactive are truly talented. I just recently picked up ArmA US version. I love it for the same reasons I loved the original years ago. It's a proven great game concept.
The only real problem I have with the game is this:
I have a purpose built gaming machine (albeit not top of the line) with an Intel Quad core Extreme cpu, dual 8800 GTSs (640 mb) running in SLI, 2 gigs of corsair Dominator ram (DDR2/800), running Vista32 and DX10, and all the latest patches and updates for software and hardware. Â My framerates are just...... poor. They jump from 75fps to well under 30fps depending on the action. And no matter what in game settings I change, I still get sub par results. My PC screams through every game I own, and that's with max settings. Â But I when I play ArmA, it's like a cpu/gpu stress test. Â Even the opening scenes of the island (as the camera pans over the landscape), my framerate jumps all over the place.
Now don't get me wrong, I know it's a trade off. There is a ton of great things about this game, and I'm sure I'll see some marginal performance increase with the release of various patches and drivers. Also theres more to do in the tweaking department on my end, but I'm still disappointed. Â Â
 I remember all the tweaking, and editing configs, and upgrading components I had to do to get the original OFP running smooth and at a constant framerate years ago.  I really don't want to go through that headache again. I guess I'll have too.
