Yeah
I see now...
well for the whirl effect (before battles)
I had this problem too...Someone help me here in fact

The problem is the FSAA and so u ve got to choose between smooth graphics
or whirl and other framebuffer effects...
For me it is all chosen...I prefer play nicely during the whole game.
So set the framebuffer to "black"
TO TELL THE TRUTH, I had never tried the soft plugin...
And i m impressed...well done pete.......
I think that this is the best plugin in term of compatibility...
For ur problem dude, me too it is the same on my PC
I just put scanlines enabled(or I play on my tv

= much better)
Oh and two more advises:
1)Take the detonator driver 12.00 (Me too I had the version U have...I gained at least 20 fps!!!!!!!!!!!!!!!!!!!!!!!!!!!!)
at
www.the-ctrl-alt-del.com
2)Just disable the VSYNC that s why the menu is at least 10 fps slower
But w/ the detonator 12.00 it should do the work
Well Bye
I hope I ve helped U as man has done for me

(If u have still problems, just quote again)
See ya dude
