Launch OptionsSteam’s launch options allow you to supercede the internal settings of whichever game they are applied too. To access launch options, you need to right-click on DayZ within steam and select ‘settings‘. Now select ‘launch options‘ and you will be presented with a single line text-box. There are a few different launch options that are useful here. - -nosplash – removes the Bohemia Interactive splash page, letting you get into the game faster.
- -skipintro - skips the intro, getting you into the game faster.
- -noPause – keeps the game running while minimized or not focused.
- -world=*empty – disables the map from loading on launch, meaning you get into the game launcher quicker, but loading the game will take longer.
- -cpuCount=8 – set this to how many cores your CPU has. Most systems are either 2 (dual-core), 4 (quad-core), or 8 (octa-core)
- -maxMem =8192 – set this to the total amount of RAM your system has, 2048 for 2GB, 4096 for 4GB, 8192 for 8GB.
- -window - launches the game in windowed mode, if that’s something you’re looking for.
- -noborder - launches the game in border-less windowed mode.
- -exThreads=7 - set this to 0,1,3 or 7 – this is the amount of threads your CPU uses. Defaults to 3 for dual-core, or 7 for quad-core.
So your launch options within the box should look something like this: -cpuCount=8 -nosplash -noPause -maxMem=8192 Configuration FilesThere are a few files which can be tweaked on your system that will give you a performance boost. First of all you want to locate ‘My Documents\Dayz\Dayz.cfg‘. You can edit this file in ‘notepad’ or any other text editor. Open it up and edit the following:
- GPU_MaxFramesAhead=1 - set this to 1.
- GPU_DetectedFramesAhead=1 - set this to 1.
now you want to open another file, you can locate it at: ‘My Documents\Dayz\<name> (where <name> is your DayZ Profile name). You can edit this file in ‘notepad’ or any other text editor. Open it up and edit the following: - sceneComplexity=100000 - this number affects your object details. Setting it anywhere from 50000 to 20000 can improve performance significantly.
- shadowZDistance=250 - this number affects the distance at which shadows are drawn, setting this to a lower value will increase FPS.
- preferredObjectViewDistance=1000 - this number affects the distance in metres that the engine will draw objects. A lower number will greatly improve performance.
- viewDistance=3000 - this number affects the distance at which you will be able to see objects. A lower number will increase performance, but setting it below 1000 will mean that you may not be able to see incoming threats like players or zombies in the distance.

(Ripped from Reddit) This is a quick-start/optimization guide as well as a general reference for DayZ SA settings in its current state (~.45).
It will cover: 1. Launch Parameters, 2. In Game Settings, 3. Config File Tweaks, 4. FOV Calculation, 5. CPU and GPU (NVidia/ATI) Optimization tweaks or corrections users share in this thread will be added. It will not cover: - CrossFire/SLI Setup
- CPU Core Parking
- Memory Allocators
- TrackIR
- Optimization for Potatoes
- How to make Friends in DayZ,
although it will provide further reading.
***INSTALL ON AN SSD IF YOU HAVE ONE***
1. Launch Parameters
DayZ is currently a 32-bit application; some of these setting may make more of an impact if/when it is made into a 64-bit application. - http://i.imgur.com/W0wMmzQ.png" rel="nofollow - Right click DayZ in steam and go to properties [1] - http://i.imgur.com/t2Hp4RG.png" rel="nofollow - Click the 'Set launch Options' button [2] -window - launches in windowed mode. see "Config File Tweaks" for resolution settings. -noborder - borderless windowed mode. -nosplash - disables the splash on startup. -skipintro - disables the intro on startup. -noPause - keeps the game running while not focused (could be useful for streaming) -world= *empty, ChernarusPlus *empty will keep ChernarusPlus from loading at startup, which results in faster load times to the main menu. However, there will be a longer delay between connecting to a server and being able to move, which could mean ***LIFE OR DEATH*** -winxp - *May help with problems using older drivers on multi-GPU systems. may cause even more problems. Use at your own risk. *HDR Quality needs to be set to "Very Low" -maxMem= 256-*2047mb 256mb is hard-coded minimum; 2047mb is hard-coded maximum (May change with a 64-bit version) -maxVRAM= 128-*2047mb+ 128mb is hard-coded minimum; 2047mb is soft-coded maximum, any value over 2GB may help or hurt performance or "result into unforseen consequences!" -cpuCount= Defines number of CPUs/cores. 2,4,6,8. -exThreads= Defines the amount of extra threads. 0,1,3,5,7. This will override auto detection (which uses 3 for dualcore and 7 for quadcore) https://community.bistudio.com/wiki/Arma2:_Startup_Parameters" rel="nofollow - source [3]

2. In Game Settings
These settings are intended to boost your framerate without sacrificing all the pretties, and are a good starting point for users to customize: Open DayZ and head to Configure>Video settings. Quality: - Objects - Low (Normal with good GPU)- Terrain - Very Low- Clouds - Normal (Disabled if you're getting random FPS drops)- Shadows - Normal (High or Very High with good GPU)Textures: - Video Memory - Auto- Texture Detail - Normal- Texture Filtering - HighRendering: - AntiAliasing - Low- Alpha to Coverage - Disabled- Edge Smoothing - FXAA Low- HDR Quality - Low- Ambient Occlusion - Disabled- Postprocess Quality-Disabled
when you are finished, close DayZ. credit: McGuyver
3. Config File Tweaks
There are two files to be changed, located in My Documents>DayZ Open with notepad: DayZ.cfg Resolution_W: 2560,1920,1650, etc. Resolution_H: 1440, 1080, 1050, etc. *Set to your monitors native resolution WinW: Custom WinH: Custom winDefW: Custom winDefH: Custom *Windowed Resolution, http://steamcommunity.com/groups/WindowedBorderlessGaming/discussions/0/846966336037436101/" rel="nofollow - borderless option [6] & http://forums.steampowered.com/forums/showthread.php?t=2675769" rel="nofollow - guide [7] refresh: 60, 120, 144, etc. *your monitor's refresh rate Render_W: 2560, 1920, 1650, etc Render_H: 1440, 1080, 1050, etc *GPU scaling - can be set in game FSAA: 1 (from game settings) postFX: 0 (from game settings) GPU_MaxFramesAhead: 1 GPU_DetectedFramesAhead: 1 HDRPrecision: 16 (from game settings) vsync: 0 AToC: 0 (from game settings) Setting this to 6 disables AA on grass, which gives you a massive performance boost. (AMD) PipQuality: 3 PPAA: 4 PPAA=1; enables a very light, basic FXAA, which puts AA back on the grass, and finishes off other details in-game. (AMD) Windowed: 0 ssaoEnabled: 0 credit: anon
<profilename>.DayZProfile "Towards the bottom there are a couple lines you'll need to edit" SceneComplexity: 600000* this changes distant object detail, set between 50000-100000010000000 is optimal "makes buildings, trees, etc, look like clay models if you set it lower"
TileSize: 12.5* this changes the quality of the rendered textures, set between 50-3.125, smaller numbers = higher quality ShadowZDistance: 100* this changes the distance shadows appear in game, set between 50-250 "the ShadowZDistance is the distance away that you'll render shadows, I'm pretty sure" viewDistance: 1800* this sets the maximum distance you can see in game. set between 1000-3000 "with my view distance at 1800m, and a scene complexity of 600k, I don't get any clay models in small towns, I haven't tried looking into Cherno or elektro yet - the human eye can't make out objects beyond 1250m, without zooming somehow, so even if you have a long range scope, you'll never need to see beyond 1800m" credit: McGuyver preferredObjectViewDistance: 1000* this sets the maximum distance player/npc models appear.set between 800-2500. Keep this number smaller than viewDistance
4. FOV Calculation Guide
Original thread can be viewed http://www.reddit.com/r/dayz/comments/ug6wu/how_to_adjust_your_fov_aka_how_to_cure_arma2/" rel="nofollow - here [8] , credit to http://www.reddit.com/u/wildcard__" rel="nofollow - /u/wildcard__ [9] Within the <profilename>.DayZProfile find "fovTop=" and "fovLeft=" These are the values that are dependent on your monitor. [Default FOV](https://i.imgur.com/aALT7.jpg) 1920x1080 - [Zoom](https://i.imgur.com/7LQq6.jpg)
fovTop=0.75;
fovLeft=1.3333334;
[90 FOV](https://i.imgur.com/ug5Gn.jpg) @ 1920x1080 - [Zoom](https://i.imgur.com/UwQgk.jpg)
fovTop=1.03;
fovLeft=1.83;
^credit: ^/u/Reutertu3
**-Cheat Sheet-**
80 FoV for 16:9 screens. fovTop=0.89;
fovLeft=1.58;
80 FoV for 16:10 screens. fovTop=1.0;
fovLeft=1.59;
85 FoV for 16:9 screens. fovTop=0.96;
fovLeft=1.71;
85 FoV for 16:10 screens. fovTop=1.06;
fovLeft=1.70;
90 FoV for 16:9 screens. fovTop=1.03;
fovLeft=1.83;
90 FoV for 16:10 screens. fovTop=1.13;
fovLeft=1.82;
90 FOV for 21:9 screens fovTop - 0.8
fovLeft - 1.87
- **Custom FOV Calculations**
- *Enter your screen resolution/aspect ratio and desired FOV into this [Calculator](http://www.rjdown.co.uk/projects/bfbc2/fovcalculator.php)*
- *Use [Google](https://www.google.com/search?btnG=1&pws=0&q=degrees+in+radians&gws_rd=ssl) to convert to radians, then round it off at the hundredths. This is your fovTop.*
- *Using a calculator, divide your new fovTop by the second number in your aspect ratio - in my case, 9 (16:9). Then multiply it by the first number, in my case 16. This is your new fovLeft, round it to the nearest hundredth.*
5. CPU, GPU (NVidia/AMD) Optimization
This section needs work, if someone with an NVidia card could post their settings that would help me out a lot For an AMD card, using CCC: AA - Override application settings, 8xEQ, Standard, Multisampling, On. Texture Filtering - Override aplication settings, 2c, High quality, Off.
For an AMD card, using RadeonPro: For an NVidia GPU: Anisotropic - 2x, AA - FXX - Force On, Gamma correction (application controlled), AA - Setting 8x CSAA is what I use, Multi-display/Mixed GPU - Single Display performance, Texture Filtering - Anisotropic sample - OFF, Texture - negative LOD Bias - CLAMP, Texture Filtering Quality - Quality, Trilinear opt - ON, Threaded Opt - Auto credit: McGuyver
