Nazari and FREEMAN, wow thank you for your very detailed posts. Nazari I apologise you've had to repost, I did search but wasn't able to find it. I'll refine my search skills. I'm not so concerned about duplication of an intensive texture. With the number of mods I've got installed I'm already running 1/4 res, low res textures and texture compression just to keep out of memory CTDs at bay. But all this helped, I went from running at 3.9Gb RAM down to 2.4Gb. It runs smooth, just not pretty. This is an awesome mod, KSP is all the better for it existing.
