Low GPU usage with ENB

[yag1z]

Yesterday I have set up Patrician enb correctly but I am not sure about Vram settings I've used vramsizetool , While I was playing the game in some areas GPU usage gets lower (%70-80) and causes stutters however when I turn off enb in-game the usage go backs to %99

Would be grateful for help.

My specs
1920*1080 display
8 GB memory
i7 3630qm
2GB gt750m sli overclocked (+450 core,+500 memory) the performance is smilar to gtx1050
1TB+64GB ssd


**UPDATE**

The problem was grass mod but still don't know why It's related to ENB...
I ve heard Skyrim uses only 2 cores of CPU so CPU frequency per cores is more important for Skyrim sadly my i7 3630qm is 2.4 ghz

I set iMinGrassSize from iMinGrassSize=60 to iMinGrassSize=75 now gpu usage is about %95-97 sometimes drops to %50s for a second and goes again normal. But not satisfied with the results still need a hand bros and sisters

The vramsize tool gives a wrong reading. See this guide (specifically, section titled A quick note on memory):

I tried and it didn't help still using %90-80-70 gpu usage in some areas other than it uses %99

#1 which other graphic intensive mods are you running with that ENB?

#2 and what size did you set for your VRAM size in the enb config?

I am using texture packs mostly 2k others 1k and grass mod , character replacers (bijiin mods and facegen mods for all other npcs)

I have set vram size 1920mb
And 128mb for swap

my guess is, that you hit your VRAM limit in ENB with a value of 1920 MB and in the non-ENB case your are fine with the 2GB of VRAM. stuttering is a symptom of running out of VRAM because it cant use the super fast VRAM anymore but need to use the RAM or load from the disk.

which value did the vram test tool report back? the 1920MB or a different one?

Vram test tool reports 2990mb sometimes 2880,2790 its results different often

Game gets lag spikes with an i7-3770k, evga 1660, 8 gigs ram. Cpu and gpu usage stays low (~40%).

quite useless information, given that you dont add what you do with your game or when the problem appear.

No kills moves, followers keep up, skyrim unofficial patch so not much. Happens mostly when you get too much stuff in a house. Happens with vanilla game also. You need to keep areas clean of drops and don't store much in your house.

too much items in one place can causes stuttering, especially if the items are non-generic. a standard iron dagger = generic item. an iron dagger with an enchant is non-generic and gets treated differently by the engine.

When you say you are not satisfied, are you getting FPS drops or stutter? If so, you can try this:

Edit - but as Grumpy posted above, there are some things that cause those issues irregardless.

ENBs are performance intensive, and flora / grass mods are even more performance intensive because the GPU has even more stuff to render

Thanks this tweak solved my sudden fps drops mostly. But I use ENB Vsync insted of Nvidia.

What is better nvidia Vsync or ENB Vsync or ENB fps limiter?
