Strange Texture Bug

[niston]

I wanted to ask if anybody has experienced similar problems:

 

When I let the game sit on pause (ESC menu) for a while, I will get this bug when I return to the game. Some textures are completely missing, some textures are just black. When I try to bring up the PipBoy in this state, the game crashes instantly to desktop.

The problem does never arise while playing the game, only if it's been left in the ESC menu for a while.

Humm, being in ESC for a while means you leave the computer for a while too? Does the screen goes black too (normal computer behavior, screen sleep or something like that, i'm sorry, i don't know how it is called)?
Here, if i'm away for a time and the screen "sleeps", when i move my mouse for it to turn back, the resolution bugs and the game goes beyond my screen, needing an exit and restart.
Maybe this is related to how engine and videocard operates? Maybe the GPU and RAM unloads game files from memory, hence why you have missing textures and crashes.

Are you running your game in FullScreen or Borderless/Fake Fullscreen?
In Falout4prefs.ini, these lines:
bBorderless=

bFull Screen=

Maybe running the game on borderless and not dedicated Full Screen *can* cause an issue?

See, all i'm saying is a shot in the dark and a question i am doing to myself, that would need testing to see if they are related or not.
I'm sorry for not really helping.
