I've found that the ESP for Arma Reforger is smooth and synced with actual player movements when I limit my in-game FPS to 60fps. I get close to 150+ fps on average in reforger and it causes a major visual desync with the actual player movements and the ESP location on screen. When FPS is limited to 60, the player movements and FPS are synced, but when I allow FPS to get higher than 60, the ESP overlay and the game moving at different speeds.
