illyuziya 1 Posted July 25, 2014 (edited) At first, sorry for my grammar, English is not my native language :( BUT I tried my best effort to help anyone who has this problemI was annoyed by this issue when I was a beginner. And search many forums for solution, many player have the same problem but still don't have a idea. Afterwards I find my way to get rid of this shit and decide to help others:1. why happen thisYour hardwares(CPU、RAM、video card..etc) aren't good enough or your computer lack of RAMSpawning zombies and items will take a numerous resource among of your RAM. Each zombies are AI, controlling them takes RAM,tooWhen zombies enraged, they will chase you and leave their cruising area and the spawnspot will spawn new zombies, which will exhaust your RAM That why this problem happens when players chased by zombies,or looting 2. SolutionIf you noticed, there are two options of video resolution in this game. interface resolution means how many resolution dots for your monitor3D Resolution essentially means your video quality, the higher you set,the more resource it will takeI was setting 1920x1080/1440x810(interface/3D ) and usually happens this issue when zombie around me.(somesay set video memory as Default will help,too. But it didn't work for my computer )*Lowered the 3D Resolution can reduce the spending of RAM,and prevent you from 'black screen receiving'However the enactment of large interface Resolution and small 3D Resolution will cause your in-game screens seems blur as myopia. So I suggest set both of them the same.My picking is 1280x1024/1280x1024 now, and seldom happen this shityou may not feel comfortable with low quality, but it is better scratched by zombies in a black screen and can't do anything.By the way, if you still have this problem after do my recommendation, do virus scanning. becouse virus wastes RAM.and trun off some unnecessary service on your computer, recall task manager and click files → click New tasks(Run...) → tape services.msc → turn off services which unnecessary and spend resource.REFERENCE Updating your computer is the best way to solve, but it costs.These suggestions should be helpful for most player. Good luck and have a good game. Edited July 25, 2014 by Myagkiy 1 Share this post Link to post Share on other sites
