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

Has anything changed/updated on your PC that coincides with this?

Do you notice any pattern to this? Does it only happen in specific areas or while doing specific actions? Or can it happen anywhere?

You mentioned that your drivers are updated via Drivebooster, however, it looks like your graphic card isn't up to date. I'm not sure if it's not updated properly or if it's just not reflecting on the system report for some reason. Regardless, you might want to try a clean install of the latest drivers directly from the Nvidia website: https://www.nvidia.com/download/index.aspx

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