Performance Issues
Hey everyone,
Regardless of hardware setup, we will all be affected by performance issues while DayZ is under development. This should of course get better as DayZ gets farther on into the development cycle. For now, try out the following suggestions, posted by Reaper (source), on how to improve the ingame fps and see if it helps.
In game settings
Now we'll set up the in game settings. At the Main Menu, click on Configure, Video.
Now set the Rendering resolution to your native resolution, the resolution next to 100%. Overall quality to Custom, VSync disabled if you don't have a 120Hz monitor.
Now click on the Quality tab, here you'll see 4 options:
Objects - decrease it if you haven't got a powerful CPU, Very low should be ok for 2-4 cores Amd Cpus and 2 cores Intel Cpus (2 Threads), low and normal for 2-4 cores Intel Cpus (4 Threads) and 6 cores Amd Cpus, high for 8 cores Amd Cpus and 4 cores Intel Cpus (4-8 Threads) and very high for 4+ cores Intel Cpus (8+ Threads).
Terrain - it affects GPU, increase it if you got a powerful video card
Clouds - leave it on Very low or disable it.
Shadows - affects both CPU and GPU, turn it up if you got a powerful GPU.
After you set up the quality settings, click on the Textures tab, here there are 3 settings:
Video Memory - set it to Auto
Texture Detail - If you got a good GPU set it to Very high or high (it doesn't cause FPS drops), otherwise turn it down.
Texture Filtering - This is the anisotropic filter, it doesn't have a high impact on performance, so if you got a good GPU, set it to high or very high.
Now, the last one, click on the Rendering tab
Antialiasing - i suggest keeping it on because it smoothes the game, but if you get low FPS disable it. Disabling it you'll get a good fps boost. For the ones who have a good gpu: You should disable the antialiasing and increase the resolution, this will improve the system usage and grant you some more fps.
Alpha to Coverage - if you didn't disable the antialiasing this option will be available, setting it to All trees + grass will not cause significant FPS drops if you set Antialiasing on low.
Edge Smoothing - Leave it Disabled or set it to whatever you like, it doesn't affect the performance too much.
HDR Quality - Set it on Very low
Ambient Occlusion - Disable it for a good FPS boost in open areas and cities (about 15-20 FPS).
Post Process Quality - I suggest to disable it, it has a medium impact on performance. If you disable it you won't see the blur effects anymore and so you won't be able to understand if your character is healthy or not. You should check how many fps you're getting with it disabled and then enabled to see which value suits best for your system.
Bloom -Set it as you like
Rotation Blur - Disable it or turn it up a little bit, it doesn't affect performance too much.
Cfg settings: video and mouse tweaks In this section, you'll learn how to properly edit the configuration files, in order to gain some more fps.
Max Frames Ahead. This fix will smooth the game, so open DayZ.cfg with the notepad (you can find it in C:\Users\Username\Documents\DayZ\), find the lines GPU_MaxFramesAhead=# and GPU_DetectedFramesAhead=# and set them to the same value (between 1 and 4) (GPU_MaxFramesAhead=1/2/3/4 and GPU_DetectedFramesAhead=1/2/3/4).
These settings won't increase your FPS but will give you the feeling as the game is running at higher FPS.
Other improvements:
Open the file named YourName (.DAYZPROFILE) located in C:\Users\Username\Documents\DayZ\ with the notepad. Now find the following lines:
sceneComplexity=# - set it to a value between 200000 and 500000 (other values are 1000000, 750000, 250000 but they require a high end cpu), it will draw less elements and reduce CPU load.
viewDistance=# - set it to a value between 1800 and 1200, it reduces the cpu and gpu load.
preferredObjectViewDistance=# - it decreases CPU load, set it to 1000 (or between 800 and 1600);
terrainGrid=# - Set it to one of these values: 50, 25, 12.5, 6.25, 3.125. Higher value = Better FPS, Lower value = lower fps but a better graphic quality. I suggest setting it to 25 or 12.5 for the best performance/quality ratio.
shadowZDistance=# - set it to a value between 100 and 200 (100 is the best for me), reduces gpu and cpu load.
For example, my parameters are:
(AMD System)
sceneComplexity=150000;
shadowZDistance=100;
viewDistance=1400;
preferredObjectViewDistance=1000;
terrainGrid=3.125;
(Intel System)
sceneComplexity=1000000;
shadowZDistance=150;
viewDistance=3000;
preferredObjectViewDistance=1700;
terrainGrid=3.125;
Mouse X and Y speeds problem fix. Probably you've seen that mouse x and y speeds are different, you can fix this issue by setting the lines mouseSensitivityX=# and mouseSensitivityY=# (located in the YourName .DAYZPROFILE file), to the same value. Also you can disable mouse smoothing.
mouseSmoothing=# - This is optional, set it to 0 to disable mouse smoothing.
Note: After you edit these files, don't change any of the in game settings, otherwise, those settings will overwrite the .cfg ones. You can avoid this by setting read only property to those files when you edit them. Suggestions I suggest you to close other programs before playing DayZ, even Steam windows, terminate the processes/applications you know you're not using, this will free up some Ram and CPU power and maybe pause your downloads/uploads. Also you'd better download Fraps and run it before adjusting your settings, to see which config gives you more FPS and update your video drivers.
It's recommended that you put DayZ.exe in high priority mode, so the system will leave all of its CPU power to it. You can do it by starting DayZ, when you're in the main menu press Ctrl+Alt+Del, open the Task Manager, there go to Details (Windows 8) or Processes (Windows 7-Vista), scroll down until you find DayZ.exe, right click on it, Set priority, click on High and then choose Change priority. (Note: this is not suggested for old systems.)
Installing the game on an SSD will improve the loading times and FPS by a lot. For a look at the original guide, please have a look here: http://steamcommunity.com/sharedfiles/filedetails/?id=216291078 Please keep in mind though that the old launch parameters mentioned in the guide are no longer supported. The only two launch parameters that are currently supported are "-newui" and "-dologs".
