Didn't originally work in with 1680x1050 resolution because the boxes were like 1m above the players heads but If you run the game in windowed then drag the game to fit the screen it fixes itself, just posting this for anyone with 1680x1050 monitors.
Yeah, this hack is completely unplayable for me. I know it was working because I saw the little text overlay in the top left corner, but it cut my FPS in half. I always play it at 60FPS damn near completely solid, but this seemed to lock it at 30 for some reason because it never saw a peep above it.
Also, the actual wallhack itself doesn't work for people in vehicles, so I was ten feet away from an entire enemy squad but had no way of knowing.
