That's absolute fiction Chambo472. BF3 introduced the mechanic. It came out in 2011.
The Nvidia 400 series was the most common card and everyone played at the most common resolution 1080p.
It was introduced to stop hill-hugging camp fests, it was to create a deterrent to camping in ridiculous glitch locations and not contributing to the objective play. Just sniping people for kills and adding nothing to the game.
By design, it prevents camping because the community wanted it and still does.
Get to a location, take your shot, risk having revealed your location or relocate. That's it's intended purpose.
