I added the mods you both recommended, in addition to the list I made above. I dropped 16 other mods. The Module Manager now shows 532 patches applied. Which is a vast improvement over the 1421 patches it applied before. I tried stepping up the resolution to 8192. Unfortunately, it still crashed when applying the color map to Kerbin. The error report showed 87% memory in use with 1,054 MB free. I stepped it down to 4096 resolution and everything loaded fine. So I have doubled the resolution that I had before. I have only gotten 55 hours into game thus far, but I am sure it will provide me with many more hours of entertainment. Thank you both for your help.

Thanks for all your work on this mod. At any resolution it is worth it. I am certain it will only get better with time. I started with the highest resolution. When it crashed, I read the error report and it showed 83% memory usage with ~1.1 GB remaining free. So I stepped it down to 4096 resolution and it crashed again. Only this time when it crashed the error report showed 80% memory usage with ~1.5 GB remaining free. When I dropped it down to 2048 resolution everything loads fine. I am still tweaking my mods to see which will cause the least problems, but everything will revolve around making KSP with the Real Solar System and Real Fuels mods as stable as possible. That was my primary motivativation in buying KSP. I did not want to play in an imaginary or fictitious solar system, I wanted a sandbox simulator that uses our solar system. It will certainly give me a better appreciation for what JPL and NASA has to do in order to deliver their payloads. Once I pair down the mods I am really interested in keeping, and getting rid of all the others, I am hoping it will free up enough memory to allow higher resolutions to be used. The mods that I know I will be keeping are: CrossFeedEnabler; CustomBiomes; DeadlyReentry; KAS; MechJeb2; RealFuels; RealSolarSystem; StationPartsExpansion; TacFuelBalancer; and ThunderAerospace. Are there any other mods you would recommend for Real Solar System?

Interesting. I get better performance (meaning it crashes far less frequently) when I run KSP.exe directly from the Kerbal Space Program folder, than I get when I run KSP_x64.exe directly from the Kerbal Space Program folder. I get the same response from running KSP_x64.exe as I get when I run it from Steam. In the case of both the 32-bit and 64-bit versions everything loads fine, but as soon as I attempt to move anything in the VAB, it crashes in the KSP_x64.exe and Steam versions. I am only able to construct and launch using the 32-bit version (KSP.exe) running it directly from the Kerbal Space Program folder. It would be nice if Steam would identify which version of the application they are executing, the 32-bit or 64-bit.

I am running 64-bit Vista Ultimate SP 2 w/8 GB RAM. I had some memory issues using the 8192 and 4096 resolutions. The "RealSolarSystem Status" window would hang when loading the color maps on Eve when using the 8192 resolution), or Kerbin when using the 4096 resolution. According to the ModuleManager, I have 1421 patches successfully applied (including RealSolarSystem). However, when I used the 2048 resolution everything loaded just fine. I am looking forward to exploring our solar system. By the way, installing the 32-bit version of KSP is not an option under Steam. Steam automatically installs the 64-bit version if your O/S is 64-bit.
