"If you have a 32-bit machine, sorry, you're out of luck. We reduced the memory load of B9 from 1.8Gb to under 800Mb, but if you're running under a 2GB per-process limit there's no way you're going to load this, or any other large packs." Just get some image viewer program,like Irfanview (im strongly recommend it) and resize all the textures to 512x512 in the mod. 32bit(24) color 1024x1024 pixels .PNG images eating up to 3mb memory each,there is even 2048x2048 pixels size texture in the mod (MK2 cockpit) wich eating up 12mb memory alone.(+model +etc textures) This game at the current state dont need the "ultragigaHD" textures,Skyrim still looking very good with 512x512 textures and KSP too Here some calculations and image with half(512x512) textures. 2048x2048 =12mb 1024x1024 =3mb 512x512 =768kb 256x256=198kb i guess you dont notice the difference,but i still have a plenty of memory and a stable 60fps...
