This caused neighborhoods to go smudgy looking with no water, greying out the option to use smooth edges, stuff like that. So far, by editing graphicsrules.sgr, I've fixed all of these problems and gotten the game to run 1920x1080. Basically, the GraphcisRules file says if the card is considered inferior, settings should be forced to all sorts of shitty presets. I told it to force great presets no matter what.
But there's still one problem. As far as I can tell, everything is back to high settings. But when I dig a hole, the tile that is placed for the hole "object" is supposed to be invisible.
It is not.
Does anyone have any idea which setting might be forcing this?
