Guild Wars 2

Might be a problem with your regional keyboard settings since it works fine here with both icelandic and US settings.

I would suggest playing at 1440×900 which is half retina res looks pretty good here and you get way higher frames.
Also apple has overclocked the 650m in the retina and it really flyes for a laptop graphics chip.

This is a very valid point which should not be overlooked Transgaming needs to step up their game if there is not to be a native client down the road.

Chelmoss you should update to 10.7.4 there are updated graphics drivers in that update atleast for amd and nvidia probably intel cards as well.

I’m dropping about 50-60% in FPS going from 70-80 stable at 1920×1080 all settings high, down to 30-40 fps at 1920×1080 all settings medium not so stable sometimes dipping when recently changed zones.
