Having Fps Drops?/Low Performance in game? this should help

[Swifty]

Performance Tips Below:
--------------------

1. Set Post-processing to Low to somewhat match ArmA2's High PP settings.

2. Stop using a RAM Drive.

3. I always suggest gamers turn off Hyper-threading technology (aka HTT) as it almost always decreases game performance. This isn't as necessary now since the game shuts down more than 4 cores and arma 2 only uses 2 cores but I still suggest it be turned off in the BIOS

4. Turn VSYNC OFF <--- this alone makes at least a 5 fps difference and makes the game much more responsive.

5. Windows Vista and Win 7 users - For optimum compatibility make sure you're running as an administrator...

Minimal PC Requirements

CPU: Dual Core Intel Pentium 4 3.0 GHz / Intel Core 2.0 GHz / AMD Athlon 3200+ or faster
RAM: 1 GB
Video Card: NVIDIA GeForce 7800 / ATI Radeon 1800 with Shader Model 3 and 256 MB VRAM or faster
OS: Windows XP

Recommended PC Requirements
CPU: Intel Core 2.8 GHz / AMD Athlon 64 X2 4400+ or faster
RAM: 2 GB
Video Card: NVIDIA GeForce 8800GT / ATI Radeon 4850 with Shader Model 3 and 512 MB VRAM or faster
OS: Windows XP or Vista

But does MY computer meet the requirement?

This website can help you analyze your hardware, select ArmA 2 from the drop down list and see how your rig measures up!

Looks like I only get 20 FPS on my pc, guess I can't play...

WRONG! Anything over about 15 FPS is acceptable and anything over 30 FPS is considered really good. This may surprise you, if you come from another FPS game where everybody sucks if they don't get 100 FPS or more

ArmA is not your average FPS, it is a military simulator. As such it's calculating the trajectory of every bullet, calculating precisely what's happening kilometers away off screen, and just generally modelling things realistically and accurately in ways that other games do not. This combined with the long view distances mean you will NOT see the same level of FPS in ArmA that you would see in a lighter weight game.

Would the game run better if I had a faster CPU?

Yes.

Would the game run better if I had a faster video card?

Maybe. If you adjust the video settings like anti-aliasing, anisotropic filtering, shadows, resolution, and texture quality does it make a big difference? The bigger the difference that makes, the more likely a better video card will help you. If it doesn't make much difference what you set those things to you are likely limited by your CPU.

I can't afford better hardware, what else can I do?

There are a lot of things that you can try to optimize if you feel that performance isn't quit up to what you need it to be. There are a couple of sticky threads for that over in the troubleshooting section, try some of these suggestions out:

this thread was taken from various other threads from arma holic i took it and put it all together i just thought this would be useful for others as it has been for me i hope it helps
