OptionsEditor.exe string not found help?

[MossyMusashi]

I would like to tweak some graphics settings and it seems that's to be done with this optionsEditor.exe

When I run it, it doesn't seem to see my graphics card, so all the options present with errors. "String not found (8049)"

or how to get the editor exe to see my graphics card?
Anyone know how to edit things like texture resolution / mip mapping?

Thanks~
