Hey guys this is seriously doing my head in!!

I have a relatively new pc which I am running FFXIV on, but for some reason I cannot seem to get the game to run at any higher than 29fps - and that's by putting it on the lowest possible res, disabling (or putting on the lowest quality) practically every setting available and hiding in a corner where there is practically no activity other than some swaying trees!!

No matter how many changes I make, it doesn't seem to wanna change from ~15-20fps.... I really cannot understand why.

What makes it even more frustrating is I have read forum after forum of people running specs worse than mine and complaining about not being able to get more than 40fps!!

Please please PLEASE someone tell me what I am doing wrong!!

Here's what I'm running:

Windows 8 (64 bit)
AMD Quad Core A10 6800K 4.1GHz (Richland)
12Gb DDR3 Memory
nVidia GeForce GT630-4GB PCI-E Graphics
The PC is connected to my 65inch Plasma full HD tv via HDMI

If someone could please tell me what fps they think those specs should be running and (if it is higher than what I'm getting) how do I get it...

Sidenote: Recently, I have needed to run the game as an administrator because of some launcher error I have been receiving (running in admin mode is the only way I have managed to bypass the error) - not sure if this would effect the fps or not but thought i'd mention it just in case...
