So I'm looking to play Morrowind on a machine with netbook-like specs. They are enough to run vanilla Morrowind just fine. What I'm wondering is this: what kind of performance impact will retexture and bump-map mods have? I remember playing Skyrim and modding the crap out of it (mainly texture stuff) and hardly seeing a performance hit. So theoretically should I see consistent performance with texture mods on Morrowind? Thanks!
