Hello guys, I am new to FFXIV and am so far slightly disapointed at the performance my brand new pc has been showing. I am wondering if there is something I am doing wrong as to why I am not getting the Performance that I think I should be. Anyways here are the details:

I am running the game on Laptop (High) in Windowed mode.

FPS (not in city or anything): Ranges from 25-29. My brother who has an older PC and a worse Card has the same settings and is getting 50+fps.

Here are my computer specs:
AMD FX-Series FX-6100(3.3GHz)
16GB DDR3 1TB HDD Capacity
Windows 8 64-Bit
NVIDIA GeForce GT 640 2GB

Any thoughts? I Feel like my performance should be a lot better... Thanks guys! <3
