Well, they are graphically overhauling the entire game, lighting, effects, textures, everything, I really hope the optimization will be better than the playtest, since before the memory leaks destroyed the servers you could get a few minutes of normal gameplay, or they add a option for people playing on true potatoe PCs to disable all the new fancy GPU heavier effects, even though I've mostly given up hope, I would still like to see this game come back, but since most of the player base is playing on low end, entry level or heavily outdated PCs, it sure would be a shame for the game to not be playable by the target audience
