Thank you for the reply Patware,

It should be noted that integrated Intel graphics does not meet the minimum requirements. While you may be able to get it playing, this doesn't mean it will always work properly. This may be the reason you are getting this error on Direct X 9 mode. Additionally, if you are able to run it in Direct X 11, then you do in fact have Direct X 11 and performance will likely be similar, if not worse using Direct X 9 mode.

I can't tell for certain if this is the cause of the issue, however, I may get better insight if you list your laptops specifications.

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