I bought Arma 2 combined operations couple days ago, did everything downloaded DayZ but, due to freezing every 3-5 seconds i can't play :/. It freezes on singleplayer arma too. Only the frame freezes not the sound. I mean you can still hear background sounds like birds, weather effects. But it also freezes on menu. Here is my system: Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120503-2030) System Manufacturer: Gigabyte Technology Co., Ltd. System Model: P35-S3G Processor: Intel® Core™2 Duo CPU E8200 @ 2.66GHz (2 CPUs), ~2.7GHz Memory: 8192MB RAM Available OS Memory: 8190MB RAM Card name: NVIDIA GeForce GTS 250(driver updated) Manufacturer: NVIDIA Chip type: GeForce GTS 250 DAC type: Integrated RAMDAC Device Key: Enum\PCI\VEN_10DE&DEV_0615&SUBSYS_00000000&REV_A2 Display Memory: 4069 MB Dedicated Memory: 997 MB Shared Memory: 3071 MB Current Mode: 1680 x 1050 (32 bit) (60Hz) My processor is really old. I thought that could cause the freezing, but i couldn't be sure. So i would be grateful if you help :)
