Clarafication on Grayed Out Graphics Options

Several graphics options are grayed out, but they are also checked. I went into the prefernces and it says they are not enable (marked "false" not "true"). I'm assuming these are not enabled, but the fact that they are checked worries me. Is there any signifcance to their being checked and grayed out?

I know the game will grey out any it does not think your card/chip can handle. I have noticed any checked and greyed out.

you can play with the script but if anything goes bad delete it and start over.

Thanks.
