-nobenchmark has solved my problem, thank you very much :-D

I had the same issue (but solved it, read below).

My setup:
Asus P8Z68 DELUXE GEN3,
Intel i7 2600K,
8GB DDR3 Ram,
a GTX 570 and a GT 210.

The GTX 570 is driving my main display, while the GT 210 is driving my second and third monitor (third using HDMI).

I solved the problem by restarting the computer (don't know if necessary) and after the computer had started I first crashed once, then disconnected both second and third display and was able to launch without problems. After that I was able to launch with all three displays connected.

So I guess the benchmark (that is not verified since I can't reproduce it anymore and test with -nobenchmark) does not work well with either just multiple monitors or multiple monitors connected to different graphics cards.

Is there a way to force a benchmark on start-up?

Thanx esas for you dugestion, i fixed ot by rining from steam with "-nobenchmark" as manager has told me... How is game runing on your computer, i should recieve almost same configuration in three days :-)

Yes, always when you don't use -nobenchmark command, so game starts with benchmark.

Can you attach your dxdiag please?

OK, I did attach the dxdiag file, but in two days i will have new computer, so i don't know if it will help you

From the Dxdiag file, it seems like the Computer's not up to ArmA3 real requirements..

Oh, that :-D, i know it, but it is running better than ARMA2OA :-D.
as was saying the problem with running the game was solved by -nobenchmark command

Seems to have been resolved.
