I own an Alienware M17X with a GTX560M and 16 GB of memory. All the games i own, like BF3 and COD BO2 work like a charm. I decided to buy ARMA 3 and immediately after installing i encounter low FPS. even lower in multiplayer. I installed MSI afterburner and HWINFO and when playing ARMA i see that when my FPS drops, so does the GPU core usage. I really think it's a programming issue and hope that this will be resolved soon. Otherwise i will never never buy a game that is not finished yet to support game developers. This issue exists since ARMA 2 and can not believed this hasn't been resolved yet. This is the first time i bought a BETA for full price and i really hope that this will be reseolved soon otherwise this is the last time i buy a BETA to help support developers at this company.
