D3D Com. Error. / PS2 CDT.

[Silencer]

Can you try starting PS2 first, then launching RTST to see if that changes it at all? We have a couple of different methods for installing the overlay now including support for when PS2 is already running.

Edit:
Ok, there are definitely still issues. I updated our known issues segment with Windows 8 problems. I think I have the problem narrowed down and in my dev environment I made a change which improved overall framerate for Windows 8, but crashing can still occur. I'm going to take some more time to solve this.
