I realize this is a memory-intense mod. I am assuming you are saying: 1. it needs to be the sole mod, or risk being memory-starved thus causing a crash. 2. I might be able to use the texture compression, which I have downloaded but not installed yet, in the 32bt KSP then it might work. 3. You state " if you use KSP 32bit, the best system wont help you much, and if you use KSP 64bit, the best system wont help you much either. Welcome to unity 4." I am assuming by that you mean, the 32bit would only have a chance at running this mod with texture compression due to the limit on a 32bit program's ability to use only 4gigs(approximately)? Also, that the 64bit is not going to allow the full use of my ram? 4. I have attempted to use this mod, as mentioned in my original post, I have tried 1. on 32bit ksp on a clean install. On 64 bit clean install. No other mods installed. Are you saying that in an install of this mod, in a 32bit clean install(no other mods) that this mod still requires texture compression to be used for it to work properly? Further, are you saying that in a 64bit install it would max my 16gigs(approximately 10-11 gigs free after OS deduction and basic resource/start-up programs)? Please expound, as I am not computer programmer, but I have been building pc's for some time and your response leaves much to question for me. Thanks. Edit: You also state "What might work is 32bit with aggressive texture compression (though a few mods, this one possibly among them do not like that)..." Are you saying that even with no other mods, this program may or may not work, it's hit or miss, in a clean 32bit install of KSP, if I used texture compression?
