Hello sosa.ijaman.
Please try to clear the C:\Users\*username*\Documents\DayZ folder and verify the game data - make sure Steam cloud sync is disabled prior to doing so - as it could possibly re-download the old config files. Please let us know if that has any effect on the issue.
Also, we have trouble finding more detailed information about the GPU you are using (do you have any further specification?) but it does appear that the GPU might be below the minimum requirements listed on the Steam store. If that was the case, then we could not guarantee smooth experience.
Regards,
Geez

Thank You for your response, yes I have cleared that folder many times but unfortunately no luck. Yes indeed, my integrated GPU is under the minimum specs for the game but it still ran it smoothly before the 1.13 update or 1.14 update. I understand you can't guarantee a smooth experience and I had an idea what may be the problem just an idea. So recently there was a problem where GTA V updated and integrated GPUs had a problem where the game would read the integrated GPUs' shared system memory rather than its dedicated VRAM causing serious lag and making the game unplayable. The same things that were happening in GTA such as textures not loading in and lag and a lot of stutters are the same thing that's happening for me in Dayz. I feel like maybe Dayz is reading/using my shared system memory rather than my dedicated VRAM after the 1.13 update, what do you think? Is there a way to see which memory type dayz is using by any chance? I also saw when going into the game on the menu screen there was a text that mentions the infusion engine. Is this a new engine being used?, or has the code or anything drastic has been done to the dayz engine to cause it to possibly use my shared system memory rather than my dedicated VRAM?
