I thought the same and i still think medieval looks better than vanilla. I am really liking the gem shaders with smaa though, I'm actually being impressed by the graphics now.
Some pics ( I added some luma sharpen in sweetx.
This one is pretty aliased, i cant get msaa working through the prefs ( It works apparently) but at least it has definition. You can get smoother edges with luma sharpen off because luma sharpen sharpens the smaa anti aliasing after it has been applied. Overall i prefer the sharper image though, with no luma sharpen nothing sticks out
