I too start having this issue since the last patch. While doing instances, out doing fates, even sometimes in housing areas. I can move and everything around me sits in one area. then from anywheres from 1 - 20 seconds area everything catches up.

I have tried updating all drivers on my computer including video card, i have tried closing down all other programs other then FF14. Only thing i have not tried is uninstalling the game and reinstalling it to see if that helps.
