Title: Performance Tips & Tweaks
Post by: KrisiS on July 02, 2015, 02:52:46 PM
Hey guys,

The following might help you to improve your performance in DayZ Mod:

Advanced Settings

Texture Detail: Set this to Very High unless your graphics card has less than 1GB RAM then incrementally go down a setting per ~256MB
Video Memory: Set to Default otherwise ArmA will not use your card fully
Anisotropic Filtering: Set to Very High, same reason as Texture Detail
Antialiasing: Using this setting will result in major performance hits unless you have a fast CPU/GPU combo, use low if you can as anything higher seems a waste.
ATOC: Disabled for performance, else either all trees or all trees + grass with a good CPU/GPU.

Terrain Detail: Up to your system specs, use as needed but generally either Low or High.
Object Detail: As Terrain Detail except this also influences the distance at which you can spot men, however unless you are zoomed in or using optics they will still be difficult to see.
Shadow Detail: This setting can result in a moderate to major performance hit, use as needed.
HDR Quality: Set to Normal, higher settings are purely cosmetic.
PPAA: Set to FXAA - Low, other settings don't seem better.

Postprocess Effects: Set to Off or Very Low, Low+ enables motion blur of which there is too much for most people.
Vsync: Off unless you are experiencing screen tearing or have a very high spec computer that is always 60fps+.




ArmA2.cfg and ArmA2OA.cfg

Both are located in Documents > ArmA 2

GPU_MaxFramesAhead=1; This may help smooth your frames and/or increase performance.
GPU_DetectedFramesAhead=0; as above.
refresh=120; This will disable VSync





Startup Parameters
Use the 'Startup Parameters' to increase performance slightly:
Right-click ArmA 2 in Steam > Properties > Set Launch Options and entering the following:

-cpuCount= set this to however many physical CPU's you have either 2 or 4.
-exThreads= use 3 for dual-core and 7 for quad-core and only if you have an Intel CPU.
-high sets ArmA 3 as a high value CPU process.
-maxMem= set this to 2048 or about 1GB (1024) less than your maximum RAM, I am not sure if higher values have an effect.
-noPause Does not pause the ArmA window when alt-tabbed in Fullscreen window mode, good for multi-taskers and streamers.
-noSplash gets rid of the intro stuff at startup.
-world=empty Starts up the game faster as it loads empty level.

Sample Startup Parameters for quad-core system:
Code: [Select]
-high -cpuCount=4 -exThreads=4 -maxmem=2047 -noPause -nosplash -skipintro -world=empty


Just to let you know that the single biggest improvement I could make in terms of FPS was to OC my CPU.

On my i5:
@ 3.4mhz = 38 -> 42 FPS in Cherno
@ 4.3mhz = 62 -> 67 FPS in Cherno
