Ive just upgraded my system to an i5 2500k new MB and a 8 gig of DDR3 ram and ArmA II still drops into the low 20's in mutliplayer and singleplayer. Now I understand that ArmA is a hungry beast but I thought at least my game would stay in the 30's and not lag with my new system. Ive just done a fresh install of Windows 7 64 all the right and latest drivers for my GFX card and everything eles im kinda stumped TBH I thought even at stock the i5 2500k would solve my bad fps drop issue.
One thing I did notice while playing online ArmA II was only using 1 core and it was running at between 40% and 60% with very little activity on all othere 3 cores.
System spec and ArmA settings below.
Windows 7 64
i5 2500k @ stock
Asrock P67 PRO
Western Digital Black 600
Corsair 650W TX
Gigabyte GTX 460
G-Skill 8GB (2x4GB) DDR3 1600Mhz
Any help is MORE than welcome thank you!
