ArmA2 / OA (low) performance issues

[DerMoor]

Just bought The combined operations package through Steam. I installed the game and tried to play but the performance was terrible....I play many other games at max settings and am 60fps or more without any problem....and When I play this game its almost as if I am getting 10 or even less fps....any suggestions to what I should do....I would love to play this game at max and I just dont understand if I exceed Recommended specs why the game performs so poorly. My specs are in my sig but here they are anyway...

AMD Phenom II x4 920 2.8ghz OC-3.36ghz
Gigabyte GA-MA770-UD3
8gb 2x4 Kingston Hyperx 1066mhz PC2-8500 CL5 240-pin
ram timings 6 6 6 18 24 2t.......orignial is 5 5 5 15 idk if is should change is back or what
Ati Sapphire toxic 1gb Radeon HD 5850 775:1125
Win 7 ultimate 64bit
H50 cooler push/pull
case is a basic atx with 4 fans one intake(along with H50's fans) and 3 exhaust.


If anyone could give me some tips on what to do I would greatly appreciate it...ps I can play COD:black ops,,Starcraft 2,,Cs:s,,HL2,,,Just Cause 2,,,Sims 3,,,,,basically anything but Arma 2 or operation arrow head.

What settings do you play at? and when do you get low fps. Some missions in the campain are pretty heavy on any system.

Best thing to compare performance is post all your settings and run the 3 benchmark scenario's.

edit: I run at:

1920x1080
2000 visibility
aa off
low objects detail
high shadow detail
post very low

rest on normal

I get 51 fps average on the benchmark 08 scenario on my q6600@3.3 and an overclocked gtx260. Vsync is on and prerendered frames set to 0.

and 46 on benchmark 01

My settings are
Vis 3600 which I will try lowering to what yours is
quality veryhigh
1920x1080x32--I am playing on a 46" led tv
3d res 1920x1080
textures normal Shadow-high(will change to what yours is as well)
vidmemory normal Hdr- normal
AF high Post Process-Low
AA off Vsync disabled(helped a little but I get screen tearing
Terrain Normal so i am going to have to enable
Objects High this)

Benchmark 1 avg 37fps
Benchmark 2 avg 11fps didnt try 8 but I will.....Idk why this is like that....so sad I really wanted to play this game and I dont see why I need to play with is looking soo crappy with dumbed down graphics.

Ok so now I changed a few things and got some outstanding results
Textures are now at high
Vidmemory is at veryhigh---actually increased my fps
af-High
aa-off
terrain-normal
objects-normal
shadow-normal
Hdr-high
postprocess-off
vsync-enabled
and I did change my visibility to 2100...my fps is now 49 or 50 in benchmark 1....used to be 37....benchmark 8 was 57 so I think i am content...still sad that some textures load in late and from far away tanks and other vehicles look 1st gen graphics until u get close then they start looking good.

I have shadows on high because that way they're fully rendered by the gpu, normal shadows are determined by the cpu.

if you look at the complexity of some of the models, it's clear why the game can run sluggishly.

imo, an optimized low poly model with superior normal mapping is near indistinguishable from a higher poly model. case in point:

you can have a hundred of these running around on the battlefield with no slowdowns. right now, lod 3 looks more complex than that.

im just going to add to the frustrated list here lol... someone PLEASE tell me how to get better preformance.

my system:
CPU: AMD PhenomII x4 955 3.2Ghz (OC'd to 3.5Ghz)
RAM: 6Gb DDR3 @ 1600 9-9-9-24
GPU: GTX 460 (800, 1600, 2000) = (core, shader, memory)
HDD: 500Gb @7200rpm
MoBo: Asus 870

i have all settings on NORMAL except for video memory = high and AA = OFF, my view distance is 2500 and im running a resolution of 1680x1050. i am only gettings 25-30 FPS MAX.

i know i should be getting better preformance than this but am not sure what i am doing wrong. any advice is greatly

one thing i notice is that looking at EVGA precision, it tells me that my GPU is only being 50-60% used while in missions but then when i hit ESC and go to menu, the FPS shoots up to near 70 and the GPU % goes up to 97-98 on precision..... is the game just not using my GPU correctly or what? i found this very odd.

[Leon86]

what do you get in the benchmark missions 1 and 08 if you run at:

1920x1080
2000 visibility
aa off
low objects detail
high shadow detail (for gpu shadow rendering)
post very low

rest on normal

?

not sure how to do this benchmarck thing, i will post back if i figure it out

Its under singleplayer scenarios.

I have very low performance while in combat even with few bots(sometimes it drops to 1-2fps sshow or massive lag). For example I get this while running b-mark @ Chernarus with intense night combat. Many trigger spawned explosions & lots of friendly ai running about seems to have no impact on performance whatsoever.

My setup:
-A2(DVD) + OA(DVD) as CO with 1.57(latest atm) and latest beta;
-NO MODS(at least for the test runs I made to make sure it wasn't mod related);

-using Advanced System Care PRO/GameBooster PRO/CPU control to max out the performance;
-latest Nvidia drivers(default(application controlled) settings in Nvidia control center);
-71GB free HDD space(defragged every now and then);
-no viruses so far spotted by KIS 2010;
-no trash on desktop(only shortcuts - I like to keep it clean);

My rig:
-Win 7 Ultimate 64bit;
-Intel Core2 Quad Q6600 2.4Ghz;
-4GB RAM;
-Geforce 9600GT 512mb(not OC'd);
-onboard sound card;
-hi cap HDD;

Ingame settings:
-1440x900 res(native monitor res);
-3D res @ 83%;
-1000m vd;
-textures norm;
-vidmem default;
-filtration high;
-AA off;
-terrain norm;
-objects high;
-shadows high;
-HDR norm;
-PP low;
-Vsync off;
