ArmA2 / OA (low) performance issues

[catito14]

It sounds like you've got the hyperthreading problem. You have to go into BIOS during bootup and disable Hyperthreading (look at your motherboard manual to learn how to do that)

Excellent!!! This works perfect. I disable HT and the game starts to run smooth . Thanks a lot guys!!

Very fine. I have a I7/950 and i CANNOT disable this.

I have a I7/920 and dont like to disable HT because its usefull for other apps,
but starting with cpucount=4 and HDRPrecision=32 smoothed everything out fine for me.

Why do you have 4GB of ram on an X58 platform catito? I thought that they all did triple channel?

What exactly does HDR Precision do? I believe that 8 is standard right?
Yes, I could check wikipedia or some place, but technical descriptions never work out in my head ^^

In another thread I wrote that the picture looks more "differentiated" with higher HDR Precision, so it improves visual quality and gives me more fps also.
About the exact technical connection to Hyperthreading I dunno, but fixin ArmA 2 performance is a lot of voodoo, anyway

So if you have a Dell computer you're SOL if you want to disable hyperthreading? What's the story with the cpu count, where can I find this?

Because the pack of ram came with 4 gb.... why do you ask? what is the reccomended count of ram for you?

the "PAGEFILE" is your virtual memory,
turn that of it smoothed the game for me.

rightclick my computer/properties/Advanced settings/visualperformance.

it takes a part of your harddrive and uses it as virtual memory only your harddrive have too read two things now, the game and the virtual memory.

in my situation that was my bottleneck..

i think when u have 2 HDD's in RAID it isnt needed, if u installed the game on second HDD

After 1\2 hours of play Vista says I've no more free memory (I have 4gb but ArmA 2 don't use more than 2gb), ingame there are a lot of rendering problems and then I have to close the game

Hi Snake!
I have pagefile turn off and it smoothed the game too.
but so you need at least 6gb of ram running Arma2 under Vista64.
with 4gb I had your same error message(memory).
ps: I'm from Italy too. I see on the forum your problems with Arma,
I solve them and maybe I can give you a little help.
feel free to PM me if you need.ciao.

the optimal ram setting for x58 platform is triple channel,
so 3gb(3x1) 6gb(3x2) etc. in real world applications there's no much
advantage(on double). sure someone on the forum knows how to
explain it better than me,sure!
but for my experience on Vista64 6gb ram are the optimum. disabling pagefile for example.
bye Catito.
