Unsure where to post this, but…
If you look at the following short clip from GTA V you can see a band of visual distortion surrounding the player avatar as it moves. The distortion is there also if you keep the player still and pan the camera. I'm not a developer (I know a little C++, but that's it), so apologies if this is a stupid question, but what causes it?
