Vram vs ram usage

[EspenB89]

Hey.

I started to check a few thing the other day with my ksp install. Mainly the system ram vs Vram usage. on my unmodded ksp ksp's Vram usage is around 120-200mb in kerbin flight with a 50 part ship, while the system ram is around 2000mb. With my normal complement of mods (around 50 including b9, opt space parts) the Vram increases to around 300mb with the same ship while the normal system ram increases to 3000-3500mb. How can this be correct? Does this mean that all the textures and graphics are saved and used from the system ram instead of the Vram which should be used for this???

In these examples i have not forced either dx11 or opengl

Im running a Asus G750 laptop with 8Gb ram and 770m with 3Gb Vram and i7 4700hq cpu

If i remember correctly Dx11 and OpenGl store the textures in the VRAM, thats why they help with KSPs memory limitation. You could try enforcing those and report the changes...

There's a bug in the Windows build of KSP running under Direct X 9 (the default) where everything stored in VRAM is needlessly duplicated in system RAM.
