Well heres a list of tried and failed: Every combo of graphical setting Found the best to be AA off, postprocessing off, everything else on normal except shadows which i set to off video memory on default arma2oa.cfg edit also helped a little using ati tray tool to enable multithreading helped a little setting the cpucount mannually in the launch parameters helped a little none of this helped it be playable tho after a fresh reboot I can get 35 fps in cherno on a 60 person server while full, after the first death its 18, after the second death, its 8fps, or, if I dont die, after an hour it ends up at 8 fps. so theres something wrong with the game, a bug that is causing this Myths: "Its super CPU intensive because of all the zombies etc" this is a myth, its not THAT cpu intensive, wow is more cpu intensive, so is battlefield 3. which both have more things going on at once. Sure if your running a dual core, your going to have a problem, as dual cores haven't been useful for gaming for about 5 years(don't kid yourself they're not) but any quad core(excluding low power arm quads) can handle the cpu load of arma2/dayz fine "its super hard drive intensive" again, not that much, sure getting an ssd helps, as it does with any game, but not enough to stop a bug from knocking a game down to unplayable FPS(a ramdisk runs at 5000 megabytes a second, about 100x what dayz can use, and it made little difference to fps, 5fps more max) unless your computer is already chugging along because other programs are accessing the disk to much for whatever reason already, then this isn't going to be your problem. "its got to render tons of zombies" yes, it does, but that doesnt mean fps should drop like it does, client renders thousands of mobs in other games of the same gfx quality without issue, this games gfx are old hat, and it also employs removing grass and heavily reducing gfx textures at about 70 yards. the fact that the fps gets worse as the games running, and during deaths shows a memory leak, which means its a coding problem. The reason this isn't being addressed is there is a mix of people, those who truely have this problem, and those who have super crap non gaming computers complaining that they "have this problem" dual core 2gb ram 5570 gfx card type people, who think they brought a gaming machine even those who don't think they have this problem have it, those who're getting playable fps of 60+, I bet after a few deaths that fps has dropped to 50(which is still acceptable) can someone test this? cheers
