Guild Wars 2

I’m using the RMBP,
and I used to get roughly 45-60fps on lowest settings, and ~35fps on highest,
now I can barely get 15fps on lowest.
Anybody else getting low performance on the Mac client?
Seems to be happening in the PC version but a little less common.

I’m getting the same problem with the FPS,
15 FPS on the 2.1Ghz RMBP
I used to get 60 on best performance, it decreased right after the April 30th patch.
I talked to the support and they have no idea what’s wrong, they just suggested me to raise the issue to developers by posting it on the forums, but I see I’m not the only one.
We should really try and bring this up so it can be fixed.
