Fallout 4 enblocal.ini memory settings

[pinky6225]

Been away from Fallout 4 for quite some time but recently installed it to try some mods, i downloaded ENB and checked what the vramtool says i could put in the memory section

 

i.e.

 

[MEMORY]

ForceVideoMemorySize

VideoMemorySizeMb

 

But the number it gives is a little bit on the huge side

 

 

Do have a RTX  3090 + 64 GB RAM so maybe thats correct but is there any point to using the force video memory / video memory size settings in enblocal or is it best to leave alone?

VRamSizeTest is a tool for testing how much d3d memory available for resources of games.
By default, memory manager of the mod configured to use with old videocards, so this tool helps to tweak for newest.
Most users believe that video memory size is all you have, but driver allow to use some amount of system memory for game resources like textures, vertices, render targets. This leads to performance degradation when vram is fully used, but greatly increase stability.
For DX9 version of ENBoost better to not set video memory size available above detected size by this tool.
For DX9 games you should use results of DX9 version of this tool, for example Skyrim LE, TES Oblivion, Fallout 3/NV are all DX9 games. Skyrim SE, Fallout 4, GTA5 are DX11 games.
If reported amount of memory is bigger than your real VRAM + RAM size, that means driver also use swap file, so for performance reasons better compute proper value for [MEMORYMANAGER] as physical VRAM size + RAM size - 2000 to keep some space available for OS. Or set automatic detection of video memory size.

 

From Boris himself I presume; in essence, increasing your memory above what your card actually has and forcing the issue will increase stability at the cost of performance. If you're not having any issues then leave it be. Or just make a backup and try the various settings out to see if they make a difference for you.
