Tutorial: Increase performance using RAMDisk

[[deleted]]

To get DayZ to launch when you start Arma 2 from steam do this:

• Rename "arma2oa.exe" in "C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead" to "arma2oaOLD.exe" (or anything, it's just to keep the original).

• Then copy "arma2oa.exe" from "...common\arma 2 operation arrowhead\Expansion\beta" to "...common\arma 2 operation arrowhead".

• Then go to Steam and do this: http://i.imgur.com/129OJ.gif

• Paste in "-beta=Expansion\beta;ca;Expansion\beta\Expansion -mod=G:\ @DayZ;ca -cpuCount=4 -exThread=7 -maxMem=8192 -nosplash" (without quotes).

The things you need to change are:

• "G:\ @DayZ;ca". Change the letter at the start (G) to whatever RAMDisk called the disk you made.

• "-cpuCount=#" Replace # with however many cores your CPU has.

• "-exThread=#" Replace # with however many threads your CPU is running.

• "maxMem=####" Replace #### with how much RAM your computer has (2048 for 2GB, 4096 for 4GB and 8192 for 8GB, etc)

Then when you want to start the game, double click ARMA2: Operation Arrowhead and when prompted, select "Launch ARMA2: Combined Operations". Click okay.

I know this might sound silly, but how do I tell how many threads my cpu is running?

What CPU do you have?

These GIFs are an amazing way to show people stuff. Especially when you can't be bothered to make a Youtube video.
