Grimrock

Installed the game, but all I can see of the dungeon is the light shown by the torches. I can see (some of?) the gui interface... direction buttons, character portraits and hands, but that's it.

I can sort of see through walls, but all I see is torchlight. Installed on steam. Any help would be appreciated.

You may have anti-aliasing turned on. The game doesn't support it.

I don't think that's it. I just went into my video card settings and there wasn't a way to turn off anti-aliasing, but I have it set to "use application settings", which I would think would do it.

Had the same problem, went into my graphics cards control panel and turned anti aliasing to application managed and everythings fine.

just reconfirming the previous posters diagnosis

Almost assuredly an Anti-Aliasing issue. Check your settings again in your graphic card's control panel, more than likely you are forcing some level of AA.
