I have installed the mod and love it so far! But I am having some issues with the graphics. First of all, in the mine, my torch was casting no light what-so-ever. I followed some suggestions to turn off HDR and that didn't really help.
My second problem is that the textures in the game don't look very high resolution to me. I looked at some of the screenshots and they looked WAY better than what I am seeing in-game. I'm not sure why this is.
