[Pandora's Tower] framedrops, sound issues

[Tomoya_]

Thanks for the reply
yes i tried to change the resolution multiple times. But not the OpenGL backend, i'll try it tomorrow when i have more time.
my first thought was that my cpu was just to weak so i tried to lower the resolution or the quality at all and even tried to overclock it like i said but it always showed the same problem.

I'll get back to you tomorrow when i'm back from college and tried OpenGL backend. More advice is appreciated
