yes i know wow is using a very old game engine but how hard would it be for them to make a new game engine and update wow to that? might let people with low end machines get awesum looking graphics due to the more efficient engine along with revamping of models etc to give them more triangles
yes i know some of you are attached to the way wow looks but how about this:
on the launcher you can choose wether or not to download the better models/textures (as they would take up quite a bit of space) and even if you have done that there is another option (either on the launcher or in game) to swap between the new and the old (if the new is downloaded)
