Something eating the FPS randomly?

[Takumi]

So my pc isnt the best, im running with everything on low and get 60 fps, good enough for me, however the game randomly dips under 10 fps and just stays like that even while paused.

For what I tested its not a pc problem because the game does this at very specific times, if not randomly 50/50 of the time:

Dying and reloading: The game spawns me in but i can see everything loading very slowly in front of me and the fps is dead at that point, however on startup it loads everything fine and works at 60 fps until 5-10 mins in.

Closing the map?: I was checking the map and after closing it the fps died again, im guessing the game hides everything while looking at the map, but it worked fine before, weird.

Switching from DLSS to No Upscaling, then applying: Doesnt always work, but sometimes switching between the two fixes it.

My thought was maybe needing to repaste, but this is a brand new laptop and i dont thin 66ºc is too hot for it.


Specs:
-11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz
-NVIDIA GeForce RTX 3050Ti 4GB Laptop GP
-32GB ram

Now i know its not the best laptop and the 4GB is bricking it, but no other game does this and like i said, it runs at 60 fps perfectly until it decides to randomly ♥♥♥♥ the fps to 10, so idk whats up w that.

Problem remains though, - why does the game just eat up 12gb+ vram at any settings

DOnt know about you but my Game only uses 6gb at mostly Epic Settings

I dunno man, this thing is weird, it can run games such as Hogwarts Legacy or Ghostwire Tokyo without issues, but then again Stalker 2 has very demanding specs... even though it looks like Condemned on low settings.

Hogwarts gets around the 4gb by not loading in the higher / highest detail levels of the mesh objects and their textures. You don't notice it until it happens to plants or bushes where it gets obviously blurry. Hardware unboxed covered that at at-least one point or more. Different games handle running out of VRAM differently, but what it generally does do, is start swapping to and from system memory at the speed of the pci-e bus link, and then you end up with 10~20fps in-stead of 60+ fps.

Drivers may get gummed up after a while and not be able to figure out what objects to possibly unload since it thinks it still needs them all, then you do a game restart and play for a bit. 4GB GPU is really old-hat these days though, 8gb GPU got cheap in 2016 with RX 480/470 release. Don't even bother with modern games when you're stuck with 4gb or less, as it's not only textures that take up the space, but models, shaders, shadow mapping, RT engine / DLSS all take up vram space too.

cause You have that vram amount... its just fills it up.. from tests it doesnt need more than 8gb at 1080p

?? ♥♥♥♥ you talking about
first off, i have an 8gb card, it's literally getting nuked into running out of vram even at lowest settings, just takes longer for that
second off, there's people with 12gb+ vram who have the same issue

game doesn't look nearly that good on lower settings to eat through even 8gb of ram alone

Yaa Thats ture

I get that as well even on an SSD. I'm thinking memory leak like some have said, because it'll be fine for the first few quickloads or whatever and then be unsalvagable. I don't think it's my specs either because it'll be relatively smooth before that and it stutters hard even if I'm starting right at the sky, ground etc.

Looks like enabling Frame Gen on nvidia cards causes this issue. I turned off DLSS 3 frame gen and the game does not have a memory leak now and I get 60 FPS on Quality with DLSS and Reflex enabled.

Same here. I get around 40–60 FPS on medium settings with a 3050 Ti, but it suddenly drops to 5 FPS and stays laggy. Restart the game sometimes helps, but most of the time, it doesn’t.

60+ FPS on 4080 Super and suddenly can go to a slideshow. If you can manage to go to the main menu and reload - the game is back to normal.
Tracked CPU, RAM and GPU load - everything on 60-70% all the time.

The town is the problem. If you are anywhere near the town it halves your fps. Outside of the area of the starting town? perfectly fine.

There's something going on. They need to fix it. Something is happening in specific areas. outside those areas its pretty good. not the best. but far from bad.

I have the same problem, but with even higher initial FPS. My FPS is around / over 100 and suddenly drops to 15 FPS... I've tried every possible graphic setting and no difference. Only in the initial FPS...

[Argus]

I got a RTX4070ti, and I'm also having the same problem. Game is running smooth for a time on epic, then, either after about 30-40 minutes play session or upon death and reload, fps just drops to 5 and stays like that, even when paused. I have to quit and restart the game to fix every time, then it happens again. Definetly memory leak problem

[feys]

not just you, happens on my high end system aswell

[Xpolicy]

Same for me. I'm running at high settings and sometimes can play for 20 minutes at 60 FPS might dip to 50 FPS sometimes then out of no where in the same map area it will just take a crap at 9 FPS and stay there until restart the game. Sometimes its only after 5 minutes of playing. Running a (laptop) 4070, 32GB memory, AMD Ryzen 9 7940HS. Dont think its hardware specs considering it runs great for 20 minutes. Seems like some sort of leak...??

Update: I have disabled Frame Gen as some others suggested and it seems to have fixed my problem so far. It happened one more time but cleared up quick.

I'm having the same problem with a TX 7800XT; playing on medium graphics everything runs fine, but suddenly it drops to 10 FPS and stays there. It's unplayable right now.

same here, 4080 Super / 7950X3D
