DayZ
DayZ
Find ways to run dayZ smoothly without lag. Your setup includes an i5-4440 and GTX 970, which causes issues at low settings. You worked around it by using medium settings with your GTX 650.
DayZ could work more smoothly on older cards. I face a similar issue with my i5 4590 instead of the 4440.
Dayz has always been a laggy game, regardless of setup. Some people suffer with HUGE lag, some people don't. It's just a POORLEY optimised game I'm afraid
