Suikoden III on Vista Direct X, 10 problems.

I installed from the offical site and added the beta after many issues and managed to make the iso open and work to the extent that it was working at an average of 26% fps (getting as far as the opening movie and main menu, the graphics seemed normal, just slow, laggy and with bad sound). I was trying to resolve this by purely tweaking the configuration when I started getting this message:

'The Gs plugin failed to open/initialize. '

Here are my graphics settings, I have tried rebooting a few times already.
Any help would be mucho appreciated
