processor and limitation of mods with script

[alain31]

hello,

 

I start having too many mods with scripts and the game starts to have slowdowns.
if i was only limited by my cpu, the problem would be solve with a better processor or the game has a limit that can not be exceeded even with the best possible processor?

thanks.

How fast? I have tons mods no slow down on AMD 8350 @4ghz with 32gigs of ram and Video card 8gb. You might want  increase the ram then.

[alain31]

hello,thanks for your reply.

 

i have 24gb of ram i7 7700k and rtx 2070 8gb vram.
i have a lot of scripting mods installed and i have mods that add a lot of npcs and monsters.
I will remove some mods and it will be better.
I ask the question on the CPU in case or if later I take a more powerful processor, i will see a difference.

I made a heavy scripted 340 mod build a while back.  Had to merge mod .esp's to get under the 256 esp limit.

The skyrim.ini has a [papyrus] section with settings that most say don't touch, it can destabilize the system.

A nice write up on it is here.

 

I was experiencing npc's bouncing off the walls in certain cells from papyrus not getting enough time and found after some experimenting my systems sweet spot with

fUpdateBudgetMS=4.6

fExtraTaskletBudgetMS=4.6

fPostLoadUpdateTimeMS=5000.0

I didn't have any fps slowdown issues with a i7 980X and GTX 1080.  If I raise the budget even higher then no doubt I'd see a fps slowdown.

 

With heavy script builds, it's a balancing act between how much time to give papyrus and how much time the frame needs to render the screen.  And having a system that can handle it.

NOT, the scripts never, absolutelly never, can cause slowdowns in the game if you have the [Papyrus] Section of your Skyrim.ini with default values.

If you have modified your [Papyrus] Section remove yours modifications and left the default values.

 

Your problem only can be caused by ONE bad script inside ONE bad mod that is generating thusand and thousand of script per second and, of course, the game is cumulating it and generating gigantic Stack Dumps on the log for alerting of the problem. The cumulation of scripts can consume all the memory of the game and cause any kind of problems, from slowdowns to stutering, frame drops, freezing...

But all the problem are caused always by ONE bad script.

 

Take a look to yours papyrus log and look if you have gigantic Stack Dumps.

Open your savegame with ReSaver and look how many Active Script you have.

Locate the problematic script and the problematic mod, remove it and see how yours problems disapear.

Yours problems not have any relation with the scripts or the [Papyrus] configuration of your game.

Put a value of 4.6 ms for execute script is totally absurd. The default value of 1.2 ms is practically never used.

Any change that you can apreciate in your game while change the values in the [Papyrus] section are pure placebo because before the asigned time is consumed all the script are in suspended state.

 

Make some test in your game. Put the value of  fUpdateBudgetMS and fExtraTaskletBudgetMS in the aberrant value of 800 and start a New Game with Alternate Start. You have 1 FPS per second? NO

Open the savegame made automatically by Alternate Start whit ReSaver and look how many Active Script you have. Maybe 50? Maybe 100? Maybe only 30?

If the game must execute 30, or 50 or 100 script why not use all the 800 ms for execute it?

Because the script are not executed in a constant way.

 

If you want more information take a look to my test mods and my blog.

Can you explain what relation can have that command with the scripts or the indicated problems?

[alain31]

thank you for your answers to my question, usually my requests remain unanswered

I had already done tests with resaver and I am usually at 30 or 50 max in active script.
my papyrus is:

 

fUpdateBudgetMS=2.0

fExtraTaskletBudgetMS=2.0
fPostLoadUpdateTimeMS=2000.0

 

i have reduced a lot of textures thanks to cathedral optimizer. i have read this guide which helped me a lot:
https://www.loverslab.com/topic/134366-processor-and-limitation-of-mods-with-script/?tab=comments#comment-2832399

 

I just put my ram at 32go, I did not think it would help me because i was pretty gpu limit, but now I'm up to 50 fps in average instead of 40.
I will still test to see if everything is ok now.
my vram was between 70 and 100 percent and use 8150 mo, it does not help either) =
it s a rtx 2070 8go.

With an i7 7700k and rtx 2070 8gb vram you must not have any FPS problem until you are playing at 4k resolution with 4k textures plus high poly mesh. You must not fill the VRAM of the video card because that can cause any kind of problems like frame drops and stutering.

 

I think you have a bad configured game or a bad ordered pluging list or some problem in HDT if you are ussing CBP or SMP. Can be some bad configured mods with some bad options but all that must be examined with detail mod by mod. For other side, i can asure you that the scripts not have any relation to the problem.

 

If you not know BethIni (link for SE) download it and execute it for optimice yours INI files and run LOOT.

Revise your CPU usage for verify that your CPU is not in 100% ussage. That can cause a lot of problems.

Run your game and look the VRAM ussage. Must not be totally filled. Reduce textures for free VRAM.

[alain31]

for the processor I use the lasso program which blocks everything when I use a game.
i know bethini everything is optimize and i use cpbc combine with htd for clothes and wigs.

I play in 1080p and I followed the nordic guide which is very heavy in graphic mod, there is high poly in there too and smim.
https://www.nexusmods.com/skyrimspecialedition/mods/12562
my mods are well organized it is easy thanks to mo2.

 

i've checked the CPU usage of the 4 core in game it rarely exceeds 80 percent, it turns between 50 and 60 percent.
the real problem is my vram, i managed to minimize the use but it rises high again.
I will continue to reduce my textures .. )=

thanks.

hello,

I have reduced a lot of textures.
I have also reduced the textures of my lods that i generate with dyndolod but I can not bring down the use of my vram enough.it takes about 7,5 go now
i have a lot of clothes mods and weapons that take up a lot of space but they are not in the levellist.
this kind of mods take vram too?

do I have to reduce the meshes too?
i put my ini to basic values with beth ini but that does not change anything.
which mods can take as much vram?

thanks.

One option for reduce Vram ussage is enable compresion in ENB. Open enblocal.ini and put:

[MEMORY]
EnableCompression=true

 

But that option can cause stuttering. Theorically, with 8 GB of Vram you not need enable compresion in ENB.

If you are ussing Cathedral Assets Optimizer run it with Compress Textures and Generate MipMaps enabled.

Without measurements of core-usage, vram, gpu-usage, temps, and so on, all of this will just be spray and pray. For example, supposedly originally the problem was cpu-usage, but now the thread is talking VRAM? Which is it now? Take measurements, so we at least know what even is the problem.

 

Also, a faster CPU won't help with CPU-usage, unless you can get SSE to use all the extra-cores. That's because moore's law and the 86-architecture is in its deathbed: Improvements in per-core performance have become marginal. What you're buying with a CPU nowadays, is more cores, fatter busses, and support for faster RAM - not so much faster cores.  Your current I7 has 4 cores. I have a Ryzen5 2nd gen with 6-cores on win8.1, and i can get SSE to use all 6 cores. So that means with the right OS/CPU-combo, you could reduce CPU-usage by at last 25%. But i don't know how far SSE can scale. For example, if you buy an 8-core, there's no guarantee SSE will actually use all 8-cores. So, i'd do some research on the web, before buying a new CPU.

Hello,
it was just a question on the cpu just to know basically if skyrim had a limit or if the limit is the cpu, for the number of scripts to use at the same time.
I do not intend to buy a new cpu, as I said above on my measurement, the game uses the 4 cores at about 50 to 60 percent never at 100 percent.
the problem came from my vram.now after having well reduced my textures, I am around 6gb use of vram and between 40 and 60 percent of charge.
it is better but in riften I can not fix the problem of fps, processor and vram are not thoroughly and I use sse fixed with sse engine fixed but I go down to 20fps when I look in the middle of riften.
it stings my eyes )= its unplayable here  )= and with resaver i have just 24 active script with this save.
would anyone have a solution to give me for this problem?

 

thanks for your help and sorry for my english its not my native language...
