Thank you for the reply Lee-Cer.

You may be running into an issue that a few people have reported. It's likely related to the new 90 fps cap in place in the game. This has created an issue with players with high refresh rate monitors.

More details regarding this can be seen here: https://na.finalfantasyxiv.com/lodes...233685e76fa452

The issue is currently being addressed, but until then, other players were able to get around the issue by using DirectX 9 mode (despite being no longer officially supported). Does this let you log into the game?

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