3DFX Glide Wrapper for D2R is in your video settings

I dont know if anyone has noticed yet but I was talking with someone in game about the old graphics settings and theres actually a 3DFX mode on the bottom of the page in the video settings.Its set to GDI but you can even set it to Glide even without the old graphics turned on.It just simulates some of how the game looked with Glide running
