I would like to provide a solution for people using AMD switchable graphics. I've tried installing old leshcat drivers but i suppose you don't need to go that far. I tried new drivers and the same problem happened: the card doesn't turn on. But if you go to RADEON SETTINGS > Preferences tab > click Radeon Advanced Settings: Look at the switchable graphics tab and see what programs are listed there, chances are for some reason unknown to me that GW2-64.exe is not listed there, click to add application find your Guild Wars 2 executable then use the high performance profile. That is it. I have added the game on the main Radeon settings app but for some reason it was not working, i even tried rolling the vbios for a unmodded version.
