Arma 2 OA only using one core

[dar 12]

Hey comunity,

I recently reset my whole system and now I'm facing the following issue:

Arma 2 is only utilizing one core correctly. Namely cpu 1 of 0-7.

On very heavy scenarios like a 30+ AI battle in Zargabad or comparable situations, the fps is dropping really fast. So i checked resmon and saw: 7 cores have do nearly nothing, 1 single core is utilized 100% all the time with the whole graph field filled.

I put

cpucount=4 -exthreads=7 -malloc=tbb4malloc_bi -maxmem=8192 -maxvram=4096 -world=empty -name=Dar -nosplash -nofilepatching -skipintro

in the exe settings in PlaywithSix.

I set cpu affinity of the arma2oa.exe process to all cores. Hyper threading is enabled. All cores are unparked and running. Win 7 Powerplan ist set to max.

Arma2OA.cfg has been modified to give the best performance (both framesahead things set to "1"). Nvidia control panel settings modified to give best performance. Physx is being run by GPU.

Arma 2 OA settings are maxed out, except for AA (normal) and Terrain Detail (Normal). View Distance is ~2000. Vsync is off. I'm running the currenty beta build.

My Hardware specs:

i7 3770 @3,4Ghz

GTX 770 4GB

16GB RAM

Arma is running on an SSD that has only arma on it. Unfortunatly I wasn't able to connect that SSD to the 6GB SATA plug as it is covered by my graphics card (who designed that mainboard? -.- ) so I plugged it into a 3GB SATA slot.

OS is Win7 HP 64bit

I hope someone can help me out with that.

Welcome to ArmA 2. This game is not like BF3/4 or any other game that utilises all the cores you have (or at least most of it).

So yeah.... live with it :)

"Welcome to Arma 2" ^^

Dude, I'm playing Arma 2 for years. I know of the limitations of that crappy engine. But before the reset, the game performed better in cpu heavy situations.

Well, then you played ArmA 2 for 2 years and did not know that it only uses one core. So, welcome to that part of ArmA 2.
