Guild Wars 2

Just finished doing this in the worst way I think it can be done.
When you enter the room if you have the game on low video settings 65% of the orbs are missing in the air. (Show in the two pictures attached) this makes it look like you have to jump these crazy lengths for each orb and you hit areas where you can’t get to the next one without finding these invis orbs in the air, what I ended up doing was placing my aoe around until I hit an orb and then used that as a spot to jump.

After I had finished the puzzle I saw someone come in and easily find the orbs jumping from one to the other, thats when I figured the code was badly done (like most things in this game) and it was just not displaying them for me. So I went ahead and upped my settings to max and true enough they were all there, going back to min they were all gone.
