The main issue i find in the game is that the missiles do crazy high G maneuvers to intercept an enemy thats far away and not doing much of anything, losing a lot of speed in the process, this inherent tracking issue, becomes even more obvious in MP, where planes are very jumpy, you can lose lock on an enemy, just because when you shoot his connection decides to launch him in outer space. That is an extreme example, but there are plenty of small yet jerky jumps when you look at a client in DCS World.
