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

It looks like something is bottle necking your system but I can't tell what from your screenshots. If it's caused by the translucent light, it may be a bandwidth issue. Does changing the graphics settings affect your FPS around these areas?

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!
