Can you tell what's different between these images?

Sorry for being vague. I need to verify something. It's a graphics detail. Try to figure it out without reading the responses.

The direction the character is facing ?

There camera is rotated and/or panned across the scene between each set of two images.

...Did I win?

At first glance I did not notice anything, but I figured it had to be something with the graphics so when I really focused and tried to find something I think it's the missing chromatic aberation (or some other blur thingy)on 1 side of each picture? Might be just my mind playing tricks when I really try to find something. Frankly I don't mind stuff like this in games.

Textures look a bit sharper/less blurry in the second pictures. Might be my eyes playing tricks though.

Is it a resolution difference ? The 1st picture of each set looks blurrier but maybe I'm imagining things ^^

At a glance, I cannot.

Can't tell much difference in the third set, but regarding the first two sets, the second picture of each set appears to be a sharper image. If I had to venture a guess, the first images are using FXAA because it appears the whole screen is blurred ever so slightly. I could also be completely wrong and seeing things.

Looks like CA to me - look at the light in the second set. Would also explain the perceived blurriness on the first pic of each set.

Is it a different thing for all 3 sets of pictures?

1. In the first the door is blurry. (I always turn off all artificial blur.)

2. Don't notice anything. It really should help to have the same picture.

3. The edge of the yellow raincoat hood has a rainbow bloom.

I tried to make it quick, and at first glance, it seems that the second picture of the first two sets are noticeably sharper than the first pictures. It becomes rather apparent when looking at peripheral details (eg the lock on the door in set one, or the pieces of paper with X marks on them in set two.) Set three seemed to be basically the same.

Well, other than the obvious character/camera position change, one picture in each set looks a little blurrier than the other.

I might be crazy but is there a slight curve to the blurry pictures? The blur is present in the pictures where the camera is at an angle rather than straight on, and the image in those pictures is sharper at the center than at the edges. It's like it's trying to mimic peripheral vision.

Thanks. Those are the responses I wanted. Yes, it's chromatic abberation. But blurriness is a good answer too. Feel free to keep replying and pretend you didn't see this post as you scrolled down to reply. It's helpful.
