FPS problem with ARMA2

[Hyuga.]

Hey guys. I've been playing Arma 2 for a couple of days now and I'm getting this strange FPS drop problem from time to time. I'm running the game on very high settings and most of the time I have around 40 FPS, but sometimes it just drops to 10 and seems to stay there for 10-20 minutes. There's usually no action or anything that could normally cause FPS drops. Perhaps there's a setting that I should adjust to get rid of those random lag spikes?

Once again, the game runs smoothly most of the times, during shootouts, explosions and highly crowded areas. The lag spikes occur totally randomly.
Thanks!

Tried lowering your rendering distance? Or whatever it's called again.. The Visibility..

[Hyuga.]

Yep :< I tried lowering almost all settings. These lag spikes just occur. Perhaps there's some solve outside the game settings

Change the 3D thing in advanced options. Make it lower than (100%)

Draw distance. :razz:

This isn't GTA SA, there's no draw distance on ARMA 2 
It's visibility settings.

Do you use DayZ Commander?

Do you use DayZ Commander?

arma 2 =/= dayz.

@OP it could be many things. What CPU and GPU do you have?
I had the same problem with my previous CPU. Arma 2 is very CPU intensive.
Maybe your video card is running out of memory.
Turn off shadows and anti aliasing, should help.

Check your GPU/CPU temperatures. A good app for that OpenHardwareMonitor. Check, what is the max during gaming.

laptop specs:
Intel i7-2630QM
Nvidia GTX560M
16GB ram

Yes, I am using dayZ commander.
The temperatures are fine. I tried lowering the 3d resolution, no problems so far. Still needs testing.

If it's a laptop, with those specs, it is most probably an overheating issue.
If in the rare case that it's not overheating, the HDD may be causing the lagspikes.

[Hyuga.]

What could I do about any of those things?

Remove your old thermal paste and apply new thermal paste between the cpu and heatsink, and thoroughly clean the fan from dust.
If it's the HDD, scan your disk for errors and see what comes out.

I would suggest against opening a laptop, especially one that still has a warranty or guarantee on it.
Just monitor your system temperatures when you have the game open and you're playing to see if it spikes to anything high while playing.
