Unfortunately Kooper, there isn't. This is just something that hardware can't fix, because the client is limiting itself.
Cliff and I experimented with removing the FPS limitation in the early versions of Windower, allowing a computer to use all of its hardware capability.
Unfortunately, we discovered that the FF developers had lazily tied things like spell timers, animation rates, ability timers, movement rate, etc, to this 29.6 FPS value. They were using it as an max-value internal timer to base everything else on.
So when we removed the limitation, suddenly the game started
freaking out, because it couldn't keep track of time anymore. You would run at mach 9 and trigger hacker alerts. Everyone on screen would animate 10x faster, making it look like all of Jeuno was having an epileptic fit. And your spell and ability timers would
appear to refresh faster as well, until you tried to use them, and the server would go WTF HAXOR.
So yeah, nothing to do about it, I'm afraid. All you can do is turn down your graphics settings to keep from dropping too far from the base 29.6 FPS value.
...and wait for FF14. ;)
