About a week ago I started getting ball movement (on ball cam) after playing rocket league for an hour or so. This is not possible and its also not possible to play the game with it happens.
Its mostly noticeable when traversing but also happens when I'm not. Its sort of like the game is lagging but I have had no problems running the game at full settings for about 2 years with my current setup. I have GX480, i7 3.4, 8GB RAM, SSD, W7. I also experienced the same issue on my predator helios a couple months ago. Here is a link to a clip.
