Just a heads up, RTX cards will crash with NVFlex enabled; I've been searching for a solution for a while now, seems like it's a known problem, and afaik NVidia and Bethesda are to blame for not updating things.
This mOd is a solution, but only for showing it being created not actually fall on the ground and move https://www.nexusmods.com/fallout4/mods/48078
Offloading to a secondary non - RTX GPU from Nvidia doesn't work either. Heck, Bugthesda, what Can you actually do? Break Pre - combs? Make 4k Texture slook like 512? Hm...
I you were like me and still were unsatisfied(read: didn't notice any difference) with the debris throwing range of this mod, double the strength values in the explosion section of the txt file included with this mod.
I also x5 the count values for the explosive weapons for veritable dirt showers when using explosives.
I discovered a minor bug that has crept up with this mod. Hitting metal surfaces with a sword or knife can cause massive fps drops, in the teens, that can last for several minutes. It has to do with the changes made to both DT_METAL, Meshes\ Debris\MetalDebris01.nif and DT_METAL, Meshes\ Debris\MetalDebris02.nif. Just delete those 2 entries out of the txt and the problem disappears.
I tried altering the values and I could only partially fix the issue, causing a momentary fps dip instead of a hang. The easiest way to achieve that is to copy the numbers after MetalDebris02 and paste them into MetalDebris01. I am yet to discover a numerical combo that eliminates the fps drop entirely.
In your Falloutprefs.ini you'll find a line that says "bNVFlexInstanceDebris=1"
While I don't know the full implications of this Option, setting this to 0 will allow debris to cast shadows! Expectedly, it comes with a relevant performance cost.
For me, with a 980 at Ultra settings, the (roughly) same sized pile of debris in my testing scenario caused a 5fps drop. That said, firing a minigun at the ground for a full minute isn't typical of average gameplay. Scattered debris from a normal gun battle will likely not have the same impact.
That would require implementation from Nvidia, as well as something in the game to actually use liquid for. (Replacing the game's water would probably murder performance too much to be worth it)
Maybe with Far Harbor we'll see flex used for some minor Water effects, and then modders can go buck-wild.

Can someone advise asap many thanks.
It needs to be installed in the main folder with fallout4.exe; NOT in the data folder.
In fallout4prefs.ini you have to add this:
[NVFlex]
bNVFlexEnable=1

or maybe 2x/3x the vanilla force version
thx
