Thank you for the update Myvar.

The difference between the screenshots are subtle and it's good that it's nothing game breaking. The first thing you should try is updating your graphics card drivers if you have not done so already.

Additionally, try tweaking the in-game graphics settings. Try enabling/disabling Glare, Shadows, Ambient Occlusion, Occlusion Culling and use low detail models at a distance. Try changing anything that will affect Lighting or Shadows and see if the error persists.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
