PAC 3 Models lag/flicker

Hi, I’ve searched up this problem many times, and have only come with 2 solutions which I have done, but still no change! From what another user said “This was a problem I used to have on a server of mine, and is now happening on a friends, which leads me to believe that it is a common problem for some people. Basically, in pac3, objects will either lag and glitch around behind you, or flicker in and out of existence as you move around. Usually only other people see these problems, and for you it’s fine. This was very annoying and people really need some answers. Has anybody had this happen or got an idea?”

Any solutions?
