Guild Wars 2

Hello fellow guild wars 2 fans!

I was wondering if someone could answer a few questions for me pertaining to a fps problem. I am experiencing 7-10 fps at the lowest possible “best performance” settings.

Here are my relevant computer specs:

Processor 2.8 GHz Intel Core i7
Memory 8 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB

I am guessing my problem is the GPU? Can anyone verify this?
And if I replace it with a gaming oriented card will that solve my issues?
Or are these just beta problems and will the final mac release be more performance polished?

Also, I read about restarting my SMC (don’t know what that is). I don’t have a retina, but could that work?

Thanks!
