Sudden FPS Drop After Dungeon

[Térazzir ☨]

I was playing this game at around 150 FPS indoors and 70–80 FPS outdoors, but after leaving a dungeon and going back outside, the game suddenly dropped to 10 FPS with no explanation.

I tried loading a save from inside the dungeon, but the issue persists. Has anyone else experienced this? I'm currently re-downloading the game to see if that helps.

Similar issues, I tanked down to single digit fps on 4090 13900K 64GB. I have not played with the settings at all yet, but others have mentioned turning off Frame Gen if you're running DLSS.

Ok, thankfully, I'm not the only person who noticed this. I was able to get it running at 25-30fps by dropping my settings to low, which is BS on my machine. I know the game has been out for all of a day, but I wonder how long until the unofficial community patch gets released. Bethesda's modding community seems to fix their games better than they do.

I had the same issues.

I’ve already tried changing various graphics settings, but the issue still persists. Nothing seems to improve the FPS now.

I don’t think we’re dealing with the same issue. In our case, the game was running perfectly fine before 150 FPS indoors and 70–80 FPS outside and then suddenly, after leaving a dungeon or going through a loading screen, FPS dropped by about 95%, down to 10 FPS or less. It’s not just low performance it’s a sudden and massive drop with no obvious reason.

I’ve reinstalled the game and manually deleted all related folders to make sure nothing was left behind but unfortunately, the issue is still there. The FPS drop persists even after a clean reinstall.

This is the thread I was looking for before buying (or not). The first couple of hours of game are all in a small "dungeon" without much going on. If performance falls apart once you hit the "open world" that tells me all I need to know.

No, i was already playing in the "open world" with no issue. It's really sudden, it's a bug not a general issue about performance. In the "open world" i was at 80 fps (130fps close space like donjon)

After this bug, even in close space i'm lock at 10 fps. So no it's not a general performance issue. The game run correctly, well not after this sudden bug.

Something like that happened to me on Indiana Jones and the great circle. Game was fine then the frame gen went all wonky.

Not had this issue in Oblivion RM yet but I'm wondering if it's something similar.

Problem solved with no action on my side

Yep just like UE5/STALKER2 It was DLSS-FG Causing this issue and eventually a memory leak for A LOT of Nvidia users.

Updating DLSS fixes it for most and increasing the shader cache size.

All AMD here maxed 1440P even lumen ultra, and its been smooth as could be! Again just like The stalker 2 days of early launch lol I was fine but had to help plenty of others for hours just willing to do so.

They apparently used a revision of UE5 not far from the one used in that game, so, makes sense.

While not bad, I guess it is bad for a lot for some reason.

But those 2 fixes were what helped most out.

It was also noted not to use Nvidia APP for games with UE5 and that helped there too. May help here as well.
