Guild Wars 2

Every time I try to limit my frame rate to 30fps, I always get a result a 20 fps. I have no idea what happened.
If without any limitation, my framework should be around 50-60fps, so it’s definitely not because of my computer’s low performance.

I got it!
Originally I got to the wrong library and didn’t find any folder named GuildWar2 !

The launch seems to be fine. When I click PLAY, a window comes up but there is nothing in it but white.
My computer still reacts, and the mouse changes when entering that white window. But just nothing more happens.
