Fallot 3 and Fallout 4 are amazing games.
Fallout 4 is notorious for long screen load times. Why? It doesn’t look much better than Fallout 3. Just sloppy programming.
The internet is rife with fixes and patches. I tried them all. None worked. But I finally found a combination that worked for me. Hopefully it will work for you.
The only thing that worked for me was:
-Move it to SSD
-Set NVIDIA Global settings to Max FPS : off , VSync : off
-Must run from Fallout.exe, not a launcher program.
I had tried everything posted.
Load times were 30 seconds on average.
Now it is 5-10 seconds on average.
I feel free!
