The game was originally developed with that API in mind, so some colors, lighting effects, and graphics settings like gamma, are only available in glide mode.
What Glide wrapper actually does (and which nobody in this forum seems to be able to explain properly) is to provide support to the 3dfx Glide graphics API, which was originally used in Diablo 2 to support the long dead Voodoo graphics cards, and that only worked in those particular cards originally. I am googling, looking at other people, everyone is saying its running smoothly etc., maybe it looks kidna cleaner, sharper … but definitely doesnt do what i asked for … I dont want better graphics, i want better resolution … Sven’s Glide Wrapper only makes it open in windowed mode.
