There is no issue when a gaming using high GPU %. The Goal is that your GPU is always at 99%, otherweise you would lose performance. With unlocked framerate this is often the case, in more demanding places like Limsa, it can drop due to many players (CPU-bound).

However, it sould not freeze - if this happens, there is another serious issue.


Please try uninstall Citrix, this is known as a problem with games.
