Sorry, I didn't read into that well enough. He meant video card settings, not game rendering settings. Still it should be configurable, I know that there are other programs wich allow you to control more propertys of your video card than the official drivers. Maybe you should try with those, or with drivers manufactured by your card specific developer.
I turned "alternate pixel centers" on through the "ati tray tools" program for my ati video card. 1) Direct 3D ----> 2) Settings -----> 3) Additional and then alternate pixel centers is listed with a check box next to it to check it on under this "additional" section. I have NO CLUE how to turn it on with an Nvidia Video Card. Sorry.
The alternative pixel center takes away the letters i and l, they are invisable.. else than that.. It works good ^^
