ARMA II System Requirements have popped up on Steam along with the ARMA II demo that was just released and here they are.
Minimum Requirements
OS: Windows XP or Windows VistaProcessor: Dual Core CPU (Intel Pentium 4 3.0 GHz, Intel Core 2.0 GHz, AMD Athlon 3200+ or faster)Memory: 1 GB RAMGraphics: GPU (Nvidia Geforce 7800 / ATI Radeon 1800 or faster) with Shader Model 3 and 256 MB VRAMHard Drive: 10 GB free HDD spaceRecommended Requirements
OS: Windows XP or Windows VistaProcessor: Quad Core CPU or fast Dual Core CPU (Intel Core 2.8 GHz or AMD Athlon 64 X2 4400+ or faster)Memory: 2 GB RAMGraphics: Fast GPU (Nvidia Geforce 8800GT or ATI Radeon 21c2 4850 or faster) with Shader Model 3 and 512 or more MB VRAMHard Drive: 10 GB free HDD spaceThe reference to a "Dual Core CPU" with a listing Pentium 4 3.0 Ghz and AMD Athlon 3200+ (Athlon XP or Athlon 64? There is a difference...) as examples is just a tad confusing and I'd place a bet that the "Dual Core" bit is an error. The recommended specs are also somewhat odd as a 2.8 Ghz Core 2 Duo (that would be either E7400 at 2800Mhz or E8300 at 2833Mhz, I guess) is a lot faster than a mere Athlon64 X2 4400+ is.
On the other hand, there are reports that the game runs poorly even on fairly high end systems equipped with quad core CPUs and high end GPUs well exceeding the recommended specs. The issues apparently are not universal across all configurations, so your performance may vary based on the exact configuration. I seem to recall similar issues with the first ARMA as well... another buggy release pushed out too early? I hope not.
ARMA II requirements have also been added to the Game-o-Meter and you can compare your system to them here.
Thanks, BluesNews.
