ArmA2 / OA (low) performance issues

[gambla]

No, it's not normal, there must be something wrong. Check this:

CPU speed = at what speed is your CPU running ? Is turbo mode enabled ?
Visibilty (view distance) = lower the better (i'm using 1600)
Video Memory = set to "default" to use full video memory
Anisitropic Filter = impact > low
Anti Aliasing = high impact > low
Postprocess = high impact > off
blood = low

Your rig looks a bit more powerfull than mine and i'm running A2AO on "very high" (AA,AF normal) at 1920x1200. With Vsync on, the FPS usually are between 30 and 60 (max).

Wow i see so money people with good pc have problems with arma. Thats strange becouse i have old athlon 6000 and old ati 4850 and 20-30 fps on AO with all setting at maximum excluding Antialiasing and Postprocessing. I recommend you turn off that AA and PP shit becouse it causes very strong damage to performance and dont set you ingame visibility too high. I prefer 4000.

most settings the highest.

dont do that. arma allows ridiculous settings, it's up to the user to find the appropriate ones.

Just more low FPS issues, but this one's pretty bad. I get about 15FPS in the bootcamp with all of the settings on absolute minimum (apart from video memory, that's on default), on my native resolution (1440x900).

My specs are as follows:

AMD Phenom II X4 840 3.2GHz
8GB RAM
Windows 7 64-bit
Nvidia GTX 550 Ti

The sort of performance I'm getting is pretty unreasonable for these specs. I know that the game's pretty bad in that it doesn't run well on anything, but I'm pretty sure with a PC like that I should be able to get performance that's actually playable. In actual campaign missions, the performance is even worse.

It runs everything maxed fine now. I just had to change HDRprecision to 8, now I can jack up all in game settings to max and still always get 30+.

How do change HDRprecision?

How do change HDRprecision?

Locate your ArmAOA cfg file in your 'my documents' Arma2 folder.

Ignore my earlier post, I did a cleanup of files and fixed registry errors and now performance is okay.

Locate your ArmAOA cfg file in your 'my documents' Arma2 folder.

There is a much easier way, on the menu screen select "Options" from the in-game menu, then "Video" and then "Advanced" and in the field entitled "HDR Quality" select the option "Normal"

According to my system specs i should be able to run this game on better settings. I have no idea why i cant play unless it is on very low? Is there some fix that i have to do? My game is bought on steam fyi.

My specs

Processor: AMD Phenom II X6 1100T 3.30 GHz
Ram: 8GB
Card: NVIDIA GeForce GTX 560
Windows 7 64-bit
