The reason for that one I think is pretty simple - it is much more ghosty there than it is in normal gameplay. There it is TAA acting on a flat image (the computer monitor is just a flat image) without motion vectors, so it is ghosting the entire time since it cannot at all compensate without proper information of what is moving.The shimmering in RE2 and it's TAA implementation is really pissing me off. You basically have to have TAA turned on or else specular detail is aliased as hell, but the TAA is causing ghosting during fast movement. You can easily see an example of it while watching Elliot on the security camera. With TAA turned on you'll see him leaving trails as he runs and pushes the zombie away.
