Problems with Chrono Cross

Hey,
I am at Lucca's house (burning) near the end of the game but I can't see anything on the screen with the exception of polygons. I've tried messing with the graphics settings and found a way to make the background visible again but it's horrendously slow, especially with the Direct3D plug-in. I was wondering if there's anything I can do to help the situation. I know it's only a short part of the game but if I would come across another similar scenario I would know what to do.

Plug-in settings (I assume it's a gfx problem so I'll just post the GPU plug-in):
Pete's OpenGL Plug-in 1.50
"Nice" setting

My specs below:

BTW, I'm using the leaked 22.50 Detonator drivers.
