Guild Wars 2

Hi,

was playing for a while when this happen. The windows crashes and restart.

I tried to login again, it crashes and restart again.

Browsing internet and running other programs on notebook was fine.

My macbook pro running win 7 ent with SSD harddisk,

It crashes whenever i login gw2 at the character screen selection for a brief seconds.

I install Mac OS X Yosemite and solve the crashing issue.

But now after logging in the game, its super lag, only 7 FPS.

any solutions ?
