Grimrock

I was tinkering with the resolutions since mine isn't supported to see which was the best and tried out windowed mode. Now the Apply button is below my monitor out of reach and I can't change the res. The game is essentially unplayable. I have it through steam, I've tried pre-launch commands through Steam properties to no avail. Does anyone know the registry path to this game or, actually, any fix would be welcome. Yes, I've tried a fresh install as well.

Have you tried editing grimrock.cfg, which is located in ...\documents\Almost Human\Legend of Grimrock?

That's exactly what I did, I thought there must be a .cfg file somewhere, but couldn't find it for the life of me. Steam likes to scatter files across my computer like confetti, but all is well and the game is being thoroughly enjoyed now. Thanks!
