From our Operation Arrowhead Review:
'Operation Arrowhead is still a massive challenge for any PC to play smoothly, so you should forget about running it on maximum settings. Bohemia Interactive claims to have optimised things for Arrowhead, but we didn’t find that it ran any faster than Arma II. This is a great shame, as when maxed out, Operation Arrowhead’s guerrilla-infested mountains are simply breathtaking to behold.
Operation Arrowhead doesn’t fundamentally change the gameplay of Arma II, so it’s still a very unforgiving mil-sim. If you’re expecting to run and gun and live then forget it, in a mil-sim such as Operation Arrowhead you have to think like a soldier to survive.'
We test this hugely demanding game at its most challenging settings, with all the detail options set to Very High and High anti-aliasing enabled. For the benchmark itself, we use a 60-second FRAPs run performed within our own custom time demo. As the benchmark is variable due to AI inconsistencies, tests are performed three times and the average result is used.
