20% is MAYBE possibel, BUT first this is not that much, and second what you link to is very likely the CPU the biggest factor, not the MB-Chipset. you cnanot compare AMD to intel, you must compare AMD to AMD and with same CPU of curse!!! same system, only different motherboard, any other compare is not valid as indictation of chipset <-> game performanc !!!

this is not true !! has nothing to do with FPS !!! (maybe 1% or 2% , if at all) --- where have you gotten such wrong and missleading knowledge ??? as long as PEG 2.0 x16 is supported, and as long as CPU is supported with MoBo this ---> every thing is perfectly fine

@Soop Sandwich: Are you SURE that a mere graphics driver update has helped ? because i dont find nothing in the AMD Patch Notes about an issue with ArmA in the ... like last 10 changelogs ! which driver have you previously had, and which you updated to ? for me the automatic update on Steam does for some reason not exist. does it not show up when having latest drivers on ??

sounds like you have a very similiar issue to mine, and i have the very exact same release of the game from steam too ! can you please look up in user User Directory/AppData/Arma Directory and check for a file called ArmA2OA.RPT open with editor and search for some thing like: Exception code: C0000005 ACCESS_VIOLATION you find it there ? if yes, we probably have teh same issue and can be debugged simulatnusly :-)
