64bit crashing at 4gb RAM usage and getting there fast

[ThatHomelessGuy]

I have 8gb RAM
and a geforce 950
KSP 1.4.2

Previously I ran KSP on 4gb no problem. I got a new computer and installed ksp and this started happening. YES MY DRIVERS ARE UPTO DATE.
Even with just vanilla it was randomly hitting a HARD 4GB limit and the game would freeze but I can still here the sounds it was making when it froze.

The Game Idles on the main menu at 3.6GB usage too so I really don't know what to do.

I have tried reducing texture quality in an effort to reduce texture memory eating up too much but it doesn't seem to have helped at all. I have found people talking about KSP as if this should only happen if launched 32bit but it won't even run in 32bit I always run it 64. I have seen online discussion about KSP using upto 16GB and others saying it's impossible for KSP to do more than 4GB ever even in 64bit mode.

What the hell is going on? It started just running out of memory like no tomorrow once I added Raster Prop Monitor or any other mod. I get to 10 mods and it hits the ram limit during loading up the game.

My last time I ran it on 4GB with about 50+ mods in 1.3.1
