Thread: Arma3 CPU Optimization

We all know that Arma2 and now Arma3 are freaking CPU hogs and even the players with top of the line computers are having some performance issues. Obviously the game is still in Alpha and we are all hoping that some of the performance and optimization issues will be solved when the game is fully released.

But for now post any links that have helped you out to increase FPS, lag issues, etc.

I've been looking long and hard for some quick fixes to my fps and lag issues and the one thing that I have confirmed to work is this.

Arma 3 CPU Optimization

1. Go to Steam Library
2. Go to "Arma 3" Right Click then select "Properties"
3. Select "Set Launch Options"
4. Copy and paste the correct launch command line below to what your system is setup for and click "OK".

For AMD CPU users:
AMD Dual Core with 4GB System Ram:
"-noSplash -cpuCount=2 -high"
AMD Quad Core with 4GB Ram:
"-noSplash -cpuCount=4 -high"
AMD Six Core with 4GB Ram:
"-noSplash -cpuCount=6 -high"
AMD Eight Core with 4GB Ram:
"-noSplash -cpuCount=8 -high"
______________________________________________
If your running more than 8GB Ram then apply this to the end of the launch line:
"-maxMem=8192"
This will allow your game to utilize 8GB system Ram instead of 4GB.
______________________________________________
Intel CPU:
For Hyperthreaded CPU's such as a Quad Core you will apply this:
-cpuCount=8
This will enable your Hyperthreads on your CPU so your CPU will act as an eight core when running Arma 3.
If you are running a Hyperthreaded Six Core then:
-cpuCount=12
If you are running a Hyperthreaded Eight Core or Eight Core Xeon then apply this:
-cpuCount=16
If you are running just a non Hyperthreaded CPU such as a Quad Core then select "4" instead of "8" same for a Dual Core you will select "2" instead of "4".
All AMD CPU's are NOT Hyperthreaded so Hyperthreaded options is highly not recommended as this can cause system failure or damage.
I will not be responible for system failure and damage if you choose to select more cores then you have on your command line!

Basically got rid of all the jitters and lag for me. I'm getting a steady 30 fps, which isn't great, but at least when I'm shooting at another player my crosshairs don't jitter across the screen as I'm trying to shoot left or right.

How to: CPU and GPU usage along with FPS in-game

I've been finding this useful to monitor actual core usage, gpu usage, temps, and frames.

MSI Afterburner also works well.

That's odd, I've heard this Won't work for Arma 3....
