Motion blur/filter in Windowed but not in Full Screen.

This does not look like motion blur.
Do you have any programs in the background running?
Close all or do a minimal boot with no autoruns via msconfig.
Do you have multiple monitors? This is especially an issue with win10 and multi monitor on different refresh rates.
Also disable game mode.

Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Unfortunately, I'm not quite understanding the issue you are having. What is the "filter they use for Direct X 11"? The video also looks normal, could you upload another so I can see the issue a bit easier?

Additionally, can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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

Hello, I've come back to inform that I have solved the issue. There was for some reason a noise filter that was coming from my monitor that was never there before, hence why I never thought to check it. My genuine thanks for your time and attention.
