Very interesting and in depth guide, thanks a lot. My main concern with P3D is indeed running out of VAS so everything in this area catches my interest. However, all of us sitting at home and doing this optimisation seems, well wrong. Is there any reason for the suppliers not doing this and supplying optimised textures? Is this sort of a "new found" or something, meaning that it was not common knowledge even by developers? Meaning also that we may receive updates soon that are indeed optimised from the supplier?
