(Just want to note that this worked for me with the specs that I have, results may vary depending on hardware)
My computer consists of the following specs:
AMD Phenom II X4 955 Black Edition Deneb 3.2GHz
CORSAIR Vengeance 8GB
First in your NVIDIA Control Panel (Not sure how AMD works, I would assume something similar), go to "Manage 3D Settings" then find ArmA 2: Operation Arrowhead in the drop down menu of games.
Set the following settings:
Ambient Occlusion - Off
Anisotropic Filtering - Application controlled
AntiAliasing Gamma Correction - On
AntiAliasing Mode - Application controlled
AntiAliasing Setting - Application controlled
AntiAliasing Transparency - Off
Maximum Pre-Rendered Frames - 0
Multi-Display/GPU Accelaration - Single Display
Power Management Mode - Prefer Maximum Performance
Texture Filtering Sample Optimization - On
Texture Filtering Negative LOD Bias - Allow
Texture Filtering Quality - High Performance
Texture Filtering Trilinear Optimization - On
Threaded Optimization - Auto
Triple Buffering - Off
Vertical Sync - Off
Make sure you hit apply to save
Then in Documents\ArmA 2 find the ArmA2AO file. Open (will probably need to right click open as "notepad" it and change the following to:
GPU_MaxFramesAhead=1; (Mouse Smoothing - off)
My in game settings are as follows (Yours may differ in terms of resolution);
(Note: Interface Size is only set to "Very Large" to get a better screenshot)
Video Memory MUST be set to "Default" to make use of ALL of your video memory
Postprocess Effects I personally have found by disabling this gives me an increase to FPS and gets rid of the blur in the game (As well as smoothing out the experience)
Objects Details by lowering this to "Normal" or even better "Low" you will(should) see a significant increase in FPS and smoothness! The only thing I have noticed this effects is the grass, but by changing AToC, PPAA, AND PPAA_Level which was stated above the picture will still make it look nice!
Vsync making sure this is disabled is important! This will make it so the game does not cap the FPS to the screens refresh rate
While I play with Texture Detail and Terrain Detail at very high, you can bump it down to High (putting some settings to low or very low can actually give your worse performance
I personally like Shadow Detail at high
So I hope some of this helps you out because I know it was a pain in the ass for me to get things going how I wanted them. But of me doing exactly what I posted throughout this post I saw awesome FPS gains and overall smoothness to my game. Even though in major cities I personally still get around 30 FPS when I am outside of the major cities I am easily getting 45+FPS. This may not be much in your eyes but it made playing the game that much more enjoyable for myself!
RAMDisk is a way to create a virtual drive on your memory. Since DayZ is only around 400MB and below you will actually be sacrificing very little RAM to get awesome speeds by loading DayZ through the virtual drive! While I did not come up with this idea first this guy did!
Check out his video guide! While you are there be sure to check out his channel for awesome DayZ videos as well! A thank you always is nice too!
Thank you and below are the links and videos I have obtained all my information from over the course of tweaking and playing around with things!
