Framerate suddenly drops to 1-3 fps on high end PCH

[Patafoin]

Damn it in the title I meant "high end PC" not "PCH".

Hi,

I just got back to Skyrim SE after more than 6 months so I just updated my mods, added a few, note that the game used to run fine before, and I started a new game.

Everything was fine at first, always between 55 and 60 fps, until something weird started to happen in Alvors house in Riverwood: the framerate suddenly tanked to an unplayable rate, between 1 and 3 fps, my CPU was at 100%, while it normally never exceeds 70%. I could barely move, so I used coc riverwood to get out and I was back at 60fps. I get in the house again and the framerate is back at 1-3 fps. I quit the game, launch again, and there's no problem anymore.

 

I play for hours and it doesn't happen again. I did the Golden Claw quest, no problem, bring it back to Lucan, and when I get out of Lucan's, out in the open in Riverwood, there it goes again, CPU at 100%, unplayable framerate... Also I notice the framerate is back at 60 fps and the CPU usage back to normal as soon as I pause the game, open the map or any menu like inventory or favorites... So I try figuring out if it comes from the ENB but no setting I un-tick helps, even deactivating the whole ENB, so I assume it's not the culprit. So I try deactivating what mods I can through the MCM but nothing seems to help. I go back inside Lucan's shop and I'm back to normal performance. Go back outside and it's a mess again. I quit the game and launch again and no problems for hours.

So I kept playing with no issues, went to Whiterun, killed the first dragon, came back to Balgruuf, get Lydia and stuff, go out towards Silent Moons Camp and as soon as I arrive, here it goes again! But this time I'm in combat so it's even more annoying.

The problem is, I have no idea how to troubleshoot this issue, it seems completely random to me. It didn't happen in my previous playthrough months ago so I'm guessing it has something to do with one of the mods I updated (quite a few), or one of the few brand new ones I added (All Geared Up Derivatives SE, CBBE SMP, HDT-SMP, KS Hairdos SMP).

Also, before anyone tells me it has anything to do with my hardware not being powerful enough, overheating or to decrease graphics settings and such, here are my specs:

• Watercooled 2080Ti - Typically runs between 40% and 80% load in-game, temperatures range between 40°C and 60°C. Nothing here seems react when the problem occurs.
• Watercooled 6700K - Typically runs between 50% and 70% load in-game, temperatures range between 50°C and 70°C. When the problem occurs, usage stays at 100% and temperature at around 80°C.
• 32GB DDR4 @ 2900Hz

How can I upload a list of my mods ?

It's been recommended to include the list as text between tags <spoiler> </spoiler>. But it does not work as I can see... Ah! Not < >, but [ ].

 

 

 

long list...

Then I just write them all down 1 by 1 ? But I have 225 mods :sad:

[shumkar]

You meant how to export the mod list... I don't know the software ways to do it (it should be some), I know only the files where this list is stored: plugins.txt and loadorder.txt. The locations may vary; the best solution is to find them by file search.There are only mods with plugins in these files.

Which mod manager are you using?

If you're using NMM, then just click on the icon that looks like a piece of paper with an arrow pointing out of it, to export your list.

Ok I got it!

Do you have many complex mods that use a lot of scripts?

 

I've found that too many of them can cause lags or freezes. Skyrim SE has a far superior engine to oldrim but script heavy mods may still bog it down.

[shumkar]

Patafoin, It is very unlikely to cause the freezes that you've described, but nonetheless RaceMenu and EnhancedCharacterEdit are known to be conflicting with each other.

[HadToRegister]

YEa, DEFINITELY shouldn't be using Racemenu AND ECE, you should use one or the other.

I do have quite a few mods that use scripts but I'm not sure I know what qualifies as "script heavy"... Immersive Citizens ? AIM FIX ? Immersive Patrols ?
