"This guide is from DayZpvp.com" As we all know DayZ is a very demanding game, in all senses of the word. ArmA 2 itself needs a good amount of RAM, CPU and GPU power itself, and the DayZ mod adds a whole other layer of code on top. Also since DayZ uses a very unique “hive” central server there is more demand on your internet connection. The game server that we play on has a huge part to play in this equation as well. You really have to make sure your rig is set up properly to get the best performance. The goal is the highest FPS or Frames Per Second that is possible for our machine. Field of view or FOV may be changed (some people can do without adjusting FOV – depends on your monitor mostly). Click here for a full guide on changing your FOV. FOV is how much can you see on the screen at any given time. Default is I think 65 but I like 80 or 85 for DayZ. DayZ Looks Amazing at Times – pic by Joss There are a lot of tweaks that you can do besides the settings in-game. If you are not comfortable changing your config files, then you might want to leave them alone. MAKE A BACK UP OF ANY FILE BEFORE YOU CHANGE IT. I will not be responsible for you messing up your installation! This is your one and final warning! Make sure that all of your drivers are up to date. Motherboard/CPU, graphics card, and sound card especially. Up to date drivers will fix a lot of issues! For the giant polygun bug going on right now try this tip from gamefoo: Got those giant shards and artifacts making the game unplayable? Fix is here: Go to Documents/ArmA 2/playername.ArmaA2OAProfile Open file in Notepad Search for “sceneComplexity=;” Change to “sceneComplexity=100000;” Save changes and exit. Launch DayZ with preferred method. Also you can make this tweak by setting “Object Detail” to “Very Low” (thx again to Szalent) A quick tip: if things are suddenly running bad you can try and flush the system. You flush by holding SHIFT and pressing the numberpad “-” key. Then let go of SHIFT and type the letters: F L U S H (flush). Your screen will go black for about 5 seconds, be careful. Graphic Card Settings The fist thing we are going to look at is your graphics card settings, not your settings in game. Weather you have an Nvidia card or an ATI card you can do this. If you have some 3rd party card then I have no idea… I will pray for you. I am not going to tell you how to find your graphics card settings, I am not a tech support guy. Good places to look are your Control Panel, also you might want to try looking in the programs list for either Nvidia or ATI. Below is an example of what they look like. DO NOT USE ANY SETTINGS YOU SEE ON THE IMAGE BELOW. I purposely made it very blurry so no one tries to use those settings. The real settings will be below the image. This is just what the panels look like, you have to find them on your own computer. You will have one of these depending on the brand of your graphics card: ATI on the left, Nvidia on the right.Graphics card control panels: ATI on left, Nvidia on the right.
