Arma II: Operation Arrowhead

Publisher: IDEA Games

From our Operation Arrowhead Review:
'Speaking of engines, 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 timedemo. As the benchmark is variable due to AI inconsistencies, tests are performed three times and the average result is used.


*Arma II has recently been updated to version 1.59, and we're in the process of re-testing cards using this new version. This is why all the cards aren't listed in the graphs below*

Behind the clock speeds, the cut-down GF114 GPU remains the same. This means that it has seven streaming multiprocessors (SMs), providing a total of 336 stream processors, rather than the eight SMs of a full-fat GTX 560 Ti 1GB. The loss of an SM also drops the tessellation unit count to seven (from eight), and the ROP count down to 28 (from 32).
Once again this is wrong. The ROP count on the GTX560 is 32 just like the GTX460. The ROPs and memory controllers are seperate from the Shader Modules and are grouped 8 at a time (4 memory controllers with 8 ROPs each; for a total of 32). The GTX560 (460) have all memory controllers operational and thus it has 32 ROPs.

The below link shows a high level overview of the GF114(104):

No other review I have read has shown anything but 32 ROPs for this card, where are BIT getting a reduction of 4 from?!

Herp a derp, my 4870 doesn't do DX11, so why has it been included in the benchmarks for DX11?

This is what the 560 should have been at launch, a significantly cheaper card with good performance.

The GTX560 was available at this price from launch. I remember seeing a few below £150 on overclockers right on launch day. BIT only reviewed a very expensive model that had no reason to exist (thanks to the GTX560TI and HD6950).
