FPS problems with interiors.

[Rinzler715]

I'm currently having major fps problems with certain interiors, example all of the Windhelm ints (the worst offenders), Bee and Barb, and a few others. I have not had issues like this before.

 

Drops are strange however, i.e. My framerate is at my 75 fps cap upon the cell loading but it slowly drops to about 5-7 frames just a couple seconds after the scene fades into view. My cpu pegs at 99% on all cores and gpu usage drops to the low 10s. Ram usage stays the same.

 

I've tested my hardware with no issues, also tested other games in my library with no similar drops.

 

I don't have any mods that affect lighting other than NAT and the problem persists even when both NAT and my ENB are disabled. My install is vanilla apart from NAT, CBBE, and few weapon and armor mods.

 

However, loading up a save (including quicksaving and quickloading) from within the affected cell removes "fixes" the issue, but exiting and re-entering the cell cause the low fps again.

 

I have a feeling it might be some issue with the game storing the previous cell loaded after entering a new cell.

 

EDIT - After testing with some other locations, I decided to test if entering an interior like Candlehearth Hall with the coc command would give me the fps drop. Using Coc to enter a cell (such as Candlehearth) does not cause the fps drop, however using Coc to enter a Windhelm interior WHILE being in Windhelm still causes the fps drop.

 

Anyone have an idea of what's causing this?

 

My specs for more info:

Ryzen 1500X

Gtx 1070ti

16gb RAM

500gb SSD (where the game is installed)

 

Thank you in advance.

Yup, similar issue for me. I don't know the solution. Some interiors, go in the front door, 10 FPS. COC to the same cell immediately upon seeing the 10 FPS, back to 60 FPS. COC to the cell directly from somewhere else, 60 FPS.

 

No difference after removing ELFX and cleaning save file with Fallrim Tools.

 

Seems to occur after about 20-40 hours of game play. New game, same cell (and load order) no problems. I also seem to first notice it in exterior cells. I don't know if it is related, sometimes I load into a city and the graphics are all low-res on buildings (probably just LODs loading instead of the normal textures), but the FPS is okay, just looks crappy.

 

Usually the frame rate drops then I notice screen flashing. Turning off the ENB helps in some cases but not all. At least it stops the screen flashing.

 

CPU memory is only at 30-40%, GPU is at 25% usage. Doesn't seem to creep upwards over time.

 

Kind of sad that this disease creeped into my game. I have had the same core load list for over a year and thousands of hours of adventuring. Only two things changed "recently". 1) updated Engine fixes, 2) installed ELFX (and patches).

 

If I find anything more concrete I will amend this topic for posterity.
