I'm such an idiot. I didn't realise that I was running a video in the background while playing ARMA. It runs fine now with both AA and Atoc enabled.

I disabled atoc. It makes the grass and trees kinda ugly but it's worth it.

Is there a way to disable antialiasing on grass and foliage and just allow it on character models? Whenever I'm standing on a field with a lot of grass my performance literally dies, but I don't want to turn off AA because the character models and weapons turn so jaggy.

I can't change the name of the files because I have the demo downloaded from steam. And if there are problems with Vista 64 I'll pass om the game till they've fixed it...

I have a C2D E8500 3,16ghz. The training missions have a lot of AI too and remember that after I try to run a scenario even the training missions break. There's nothing wrong with the RAM, because it gets reset when you restart the computer but the only way to fix the bug is to reinstall the game. And no, I do not have problems with other games. I play games that are supposedly more demanding ( Crysis, 32 FPS average in the benchmark on Very High 1680x1050 8x AA ) I run Vista 64-bit.

Meh, I really want the game but I'm so afraid of this issue being in retail too... That'd be 47.99 down the sink... Still considering of I should take a leap of faith or not. :/

I'll summarize it: All training missions runs fine. Upon running one of the scenarios, the demo "breaks" and the framerate becomes unplayable, including on the training missions. Only way to fix this is by reinstalling the demo.

Ok, so I found out what happend. I can play any training mission fine, but touching the scenario breaks the entire demo. This is NOT a performance problem, my computer can handle this game. This is a BUG. I want to know if this exists in the retail version, without confirmation that it doesn't - I will NOT buy it.

I have. No one has the same problem as me, they just have general performance issues.

I'm not sure what you mean... Settings didn't increase FPS.

What does it do? Did you have the same problem as me?

I downloaded the ArmA 2 demo and maxed out everything, an exception for the fillrate which I kept at 100%. I started out with the Boot Camp training and I was suprised of how well it ran! Averaging around ~45 FPS and looking great. So I finished the training and was eager to try the scenario... But in the scenario my frames were low single digits. 2-9... So I went back to check the performance in the training again... But no... The framerate was far lower than it was earlier (5-15) so I thought it might be a memory leak so I restarted the game but nope. Still the same... I tried playing around with graphic settings etc but nothing helped so I re-downloaded the demo and the great performance of the training was back! But as soon as I tried the scenario the same thing happend again... So my question is: Was this a known issue that has been fixed in the retail version? I don't dare buying it before I know for sure that it won't happen for me in the real game.
