ArmA2 / OA (low) performance issues

[MavericK96]

4.8 is a easy setting. But to get 60fps in Cherno you need to have allot of settings lowered and a low Rez (1280/1024). Thats to stay at 60fps with Vsync. Not going to talk about the VD(2k or less)

They claim more or less max settings at 1920x1080...

I am skeptical.

And a lot of the various tweaks and fixes found here:

I didn't read that entire post, but this:

Anti Aliasing: Increases resolution around edges so you get less jaggedness. Note the AToC notes above: If disabled, trees will not be affected (But AToC is enabled by default).
Low = 2x MSAA
Medium = 4x MSAA
High = 8x MSAA
Very High = 16x MSAA

Is totally false. Very High is NOT 16x MSAA. It's more like 4x MSAA. Because you can also go above Very High from 5 to 8, so what exactly are those? 128x MSAA?

Right VH AA is 4X. And for Nvidia, they use different combos of "Q" and MSAA by default.


- Low and middle = 2x MSAA
- High and very high = 4x MSAA
- 5 = 8x MSAA 4x + CSAA (8x called in Nvidia drivers)
- 6 = 8x MSAA (called 8xQ in Nvidia drivers)--------------------------ATI is 6X
- 7 = 4x + CSAA 16x MSAA (called 16x in Nvidia drivers)
- 8 = 8x MSAA + 16x CSAA (called 16xQ in Nvidia drivers)---------ATI is 8X

I've been having this problem that I really hope someone here can help me with. When I run operation arrowhead (for dayz) and play I get game freezes and stutters. Sometimes they last for 1 second, sometimes they last for 20 seconds and the screen becomes grayed out and I get the hourglass. I'm not sure what the problem is, my computer can definitely handle this game.

My CPU is an i7 950 and I have a gtx 560ti. I had read that my freezing could have been caused by hyperthreading, but I disabled it and nothing changed (then I also found out that problem had already been solved with an older patch.) So i'm at a loss.

I've set the video options as low as they go and I still get it, so I'm not sure what the problem is. I've made sure that there were no background applications running that could possibly be slowing me down.

Is anyone else having this problem?

EDIT: Also, I'm running the newest arma 2 build 95417. It was occurring on a previous version as well.

The stuttering or sudden drop in framerate is due to the game loading new textures. There's no easy way to fix this, check to see if your swap file is big enough (i.e. not full). Otherwise you could look into making a RAMdisk (search the general forum or just google - it's a big thread) or taking the SSD plunge.
Edit: If you have two physical HDD (not partitions) make sure the swapfile isn't on the same HDD as Arma. Google it if you don't know how.

The 20 second freeze with the hourglass I will assume is the game if it's the big green hourglass. That happens when you're unconscious usually due to low blood (<3000).

SSD removed those stutters entirely for me. Highly recommend that option.

I have the same graphics card but with following hardware: 8 GB DDR3 ram, AMD FX 8120 @ 3.5ghz

I am able to get 40-70fps on default settings. Your Cpu is the problem would be my bet.

My swap file is full, but it isn't on the same hard drive as ARMA. I do have a SSD already, would it solve all my problems if I moved my arma over to my SSD?

I didn't mean the hourglass in game (in fact windows doesn't use the hourglass anymore so I probably shouldn't of said that.) The game freezes and the window becomes not responding for about 10-20 seconds, then it goes back to normal.

Hourglass-related artefacts:
Try turn off SuperFetch, temporally[in registry] in "EnableSuperfetch" key, set to "0".
Also in case of AMD FX CPU's [similar issues/specific expected for iNtel Haswell aswell] to turn off built-in prefertcher too,
Because built-in[into CPU]VERY aggressive prefetcher seriously interefere with system prefetcher, so try "EnablePrefetcher" set to "0" or "2".
Corresponding fix applied to recent Linux kernels and expected to be added by Microsoft too.

You could just expand the swap-disk first (again google, I don't remember the step-by-step guide but it's a setting in windows). If you're still bothered by stutter/drop in FPS you need to move Arma to SSD. This isn't a simple copy/move command though. You need to uninstall first, then reinstall on the SSD. Make sure you have enough space.
