Demo Graphics - black and white background objects/textures

[Cabin]

I've been perusing the current threads and haven't found anything similar to what I'm experiencing, so hopefully someone will be able to help.

I just downloaded the demo today and noticed it is very difficult to see anything, even near candles. Background objects and textures also seem to be in black and white. However, other things do have colors, such as the pink/purple trail you are meant to follow.

I have already tried running through the troubleshooting guide and lowering all the options to the lowest qualities, but to no avail.

Here is a picture of what I am experiencing:
