While this may not help everyone, if you're having low FPS drops and your CPU and GPU usage is low try the following:

in /steamapps/common/Valheim/Valheim_Data folder
open the boot.config file and add the following 2 lines to the top:

gfx-enable-gfx-jobs=1
gfx-enable-native-gfx-jobs=1

This should increase your CPU and GPU usage and as a result increase/stabilize FPS.

To devs: possibly consider updating the boot.config to include those 2 options via a patch?

Low-level systems also need optimization, for example, my system is in the middle between the "minimum requirements and maximum" listed on Steam. i3 2.8GHz, GTX 750 (2gb) and 8gb ram, I have wild system overloads, the video card heats up constantly, from 40 degrees the temperature rises to 70, the video card uses 700 MB, but the load is up to 99%.
I understand that my system is not the newest, but it falls between the "minimum and recommended" requirements of Steam. We look forward to and hope that the game will be optimized

Ive been looking for this. My PC handles Tarkov/Rust/etc with max graphics but Im getting huge lag on Valheim all of a sudden. Until 20h of playtime it ran smoothly. Now its unplayable lag unless I change to a secondary map. And even then it doesnt seem optimal

Launching the game, will sit around 70-50fps but after 10 minutes pass, the frames start to gradually drop to the low 40's, mid 30's. As more time progresses, it will drop to low/mid 20 fps. Also, there are moments when the game will pause (can't move) for a few seconds. Restarting the game will resolve the slowdown but will start to come back. I also tried adding the 2 lines to the boot.config files and did not resolve the issue.

Yorks suggestion of editing the config file improved my performance!

In my native resolution of 3440x2440 fullscreen, it brought my average FPS from 15 to 30

in 1920x1080 windowed it brought my FPS from 30 FPS average to 60!

This simple edit is an improvement but the game is still running worse than id expect it to with my hardware.

It speaks volumes for the game that I am hooked even though it runs poorly, thanks for being the first early access game to do early access right! I wish you luck with ironing out all the bugs!

Hello there !
I've been experiencing issues about my FPS, and it's only in Valheim !

I run the game at 60FPS in very high, I can play it for 5 min, and then I have several FPS drop for like 5 secondes (2/3 FPS), and then it goes back to 60FPS during 30 secondes, then go back to 2/3 FPS etc. Changing the graphics to low doesn't change anything.. and it's only in this game, Kingdom Come run constantly at 60 FPS with no drop..

I have no problems in areas without player-built structures. Ocean is 170fps, a black forest or swamp is 100-120fps, but go to our player-built village and it drops to 20-40fps. We're not doing anything insane either, like rows and rows of campfires or smelters. A few houses, stacked chests for our stuff, 2 common smelters, etc.
CPU and GPU utilization both under 50%, not even a single core ever maxes out (which I usually find is the case with games like Minecraft). Clearly there are unused resources.

FWIW, on Linux the game runs much better if run with OpenGL. Perhaps running the game on OpenGL could also be introduced on Windows.

Upon startup in singleplayer, the game will run relatively well. In the settlement that I've built up with friends, it will usually dip around 35-40FPS while in any other environment, it typically runs anywhere from 60-90FPS. As I play longer the FPS will begin to drop but only in the vicinity of our settlement. It typically remains strong when exploring. Once another player joins, the FPS in our settlement will drop to around 25-35, while still remaining pretty solid in any other areas. Again, as we play longer, the FPS begins to drop in the town, to the point that it's at around 15-20 FPS max. My friends share the same experience.
Our theory is that either there is a memory leak or the game is not utilizing resources efficiently, only using 15% CPU and 30% GPU.

My gf pc is having more issues. It is 1050ti 4gb + R5 1600af and its runming at 30 fps with drop even below 20 sometimes. Changing graphic settings doesn't make any difference. Both running in exclusive full screen mode. I will try today change that boot file and see the results.

I'm a software developer but not a developer for this game, and I think its worth explaining something here:

Having high-end hardware does not fix procedural/algorithmic difficulties. In many cases there is little difference between an old single-core CPU and a super high-end core i9. The key thing is that an 'oopsie' in algorithmic terms can often mean your code is _thousands_ of times too slow for moderate amount of game-state/data but having high-end hardware will only accelerate you by a factor of 2x (or maybe 10x).

These kinds of performance bugs are often very difficult to isolate and even more difficult to fix. If you want to help the developers stop posting your system specs and start trying to isolate the problem. "my FPS was slow so I deleted all my buildings/structures and I noticed my framerate went up" or "I deleted all my torches and tried to remove any other sources of particle effects and my framerate didn't change" is actionable info.

I have a fx-6100 and an HD 7770 2gb with 16gb of ram. OS: Manjaro. Kernel: 5.10.15-1

My fps are stable enough (around 40) as soon as I load the game, but the more of the map I load in the more it struggles, till eventually I'm sitting at a cool 5fps with severe input lag. Structures are harder to load than empty map.

The Issue got better after the last update, but it's still bad.
Also important to note is that graphics settings have very little impact on this. I can switch between high to low draw distance and low to medium vegetation without any visible impact on performance.

I also noticed that my CPU usage refuses to go above 50% while in game. I have 6 cores, it would be nice if they could all be used.

Using the hack method of editing those boot options made the game run smoother for a little bit (looked like 60fpsish)
Buuuttt, I got severe ghosting and frame desyncing. The screen would flash white rapidly when moving my view.

But it is also the case that I suspect these guys are more focused on feature-completeness right now than they are on performance.

When making software a typical approach is to try and build all your features first and worry about performance later. Once feature-complete we let QA discover how/when things get slow (which for a game like this is likely going to involve building a lot of game state; IE a lot of buildings, bosses, character progression, etc), then attempt to reproduce the slowness under profiling tools (eg developer.nvidia.com/nvidia-visual-profiler, or docs.microsoft.com/en-us/visualstudio/profiling/profiling-feature-tour).

Once a particularly hot piece of code has been identified, after a bunch hand-wringing a serious re-implementation will begin, typically by trying to identify which body of performance bugs you're in (search, realloc, thrashing...), and finding the paper (typically from the 70's) who solved that problem elegantly, and re-implementing accordingly.

Not sure if this is helpful, but on Linux Mint 19.3 with Nvidia GTX 1080 and an i7-7800x the game runs fine. Never drops below 60fps (which feels fine for a game like this). Mostly it is running between 65 and 130 fps.

I have the same issue, but it only seems to be really bad around the area that i built my base. I did kinda build a very large castle, but the fps drop is like less then 10fps sometimes. It gets bad. And its over time. I start the game, even at my base with perfect fps, then after about 10-20 mins it just starts to drop. Im running AMD FX 8350 4.0GHZ Eight core processor and Geforce gtx 1660 w 6gb vram, and 16gbs of ram. I dont feel like i should be getting the fps drops i am.

I do believe this is not a CPU load / GPU load issue, but either an optimization or physics bug.

Ryzen 1700x @ 3.8ghz, 32gb ram, RX480 8gb gpu, 50Mb down 5Mb up fiber line

100fps in Plains, take portal to Storage area with ~ 80 chests (~20% full), the building isn't complete because during construction the area became unplayable.

4 player server, main base ~30-50fps, being in the `storage` area knocks the game down to 12-24fps, it feels like garbage.

Either it's due to complex 'building support' calculations (cpu load is 22%, GPU @30%) or there's some Chests overlapping causing an issue / syncing chest contents is an issue.

~ 4fps difference between 800x600@60hz (with lowest possible settings) and 2160x1440@144hz (max settings minus AA), with no difference in CPU or GPU load, and the RAM usage looks good at 2-2.3gb.
Not using Vsync.

Frustrating, but hopefully just a bug

My system is not far from the initial post, which claims his FPS drops a lot. Weird. It could be something else than raw power. Could it be HDD vs SSD?

For those complaining about over-heating, make sure to enable VSync in the settings. I had this happen to me in various other games which default to VSync Off. Unless you have good cooling, your GPU will overheat at full capacity.

I don't seem to have slow FPS, at least from starting the game to actually sitting in a cabin. I cap out at 60 FPS during the launch screen, the game loads at 120-ish FPS, and then when I was in the Plains in one of my cabins, I was getting 95 FPS just standing there.
Game doesn't show up in GeForce Experience. I mostly play with SteamLink which maximizes the resolution automatically. I've changed the resolution settings several times but every time I restart the client, it seems to go back to 4k (I am on 1080p laptop playing over the LAN with hardware and I can't read the map, and haven't tried scaling up yet in-game). Randomly, but briefly, I experience some graphic tears mid-game but nothing constant; I want to blame SteamLink for that though.

Xaker_Two

I have suggestions to dev about settings, that may help a bit with that

shadow settings:
- add turn off option - yes 2021 and no shadows
- shadows of local light sources only on high - i can't stand in area with smelter/kiln/campfire/forge/etc if it's more than one - i have 5 in radius of 4 std floor

add shaders quality setting or either fog disabling/density - it's very annoying when you mining and can't see what you mining!

"fullscreen" rename to "borderless window" and add real fullscreen that will require restart(to launch with " -window-mode exclusive" arg, not sure how it will work on Linux)

Also AFAIK on latest versions of Unity it's hard to achieve FPS more that 60 - one frame with empty scene on hi-end build take ~17ms (1 second is 1000ms)

When I first load in, I'm easily above 60 FPS default settings @ 1080p, but after about 5 minutes of play it starts dropping, and never recovers. Lowering settings doesn't make any difference.

Saw this thread on Reddit speculating that the issue is related to landscaping, thought it would be worth mentioning here: https://www.reddit.com/r/valheim/comments/lqcr88/reason_behind_low_fps_and_huge_instance_numbers/

While I haven't gotten huge lag yet, I feel like my game is starting to run slower as my base becomes developed with more buildings and my friends and I have gradually started to get more desync issues. I don't know if this is related or just a coincidence.

Performance issues feel lessened when we are away from our base in a swamp or forest.

OS: Win10 Pro 64bit

best rate has been 12-15 fps / 60-100 ms. The last day or so it has degraded further to 3-4 fps 333 ms. I bought a copy for my son and he runs an older machine. The game runs flawlessly. I setup a dedicated server as an experiment. My performance was unchanged... and the game ran flawlessly for my son over IP Join. I do not play online but our home speed is 1 GBit down, 42 up.

I have stripped everything out of memory and tried every online suggestion incl the run bat script to auto set the game to have High priority. No other system issues and I have never had this occur -- I tend to own high end machines because I develop, build 3d animations and content and more. On my main desk side PC the system shows usage:
CPU: 6%, Memory: 12%, Disk: 1%, Network: 0%, GPU: 9%, Power use: Low

Buddy of mine having similar issue. Less than 10 FPS no matter settings. He can play more demanding games at a way higher FPS but Valheim just tanks everything. His current setup is:

amd ryzen 5 3600
16 gig ram
AMD Radeon RX 580.

EDIT: I did get him to try the current workarounds being talked about like Task Manager priority and all that. No change in performance.

low fps have to do when building mutch or big stuff. but it needs to be more optimized

We have a very large village compound type base with lots of structures and our average FPS will range 35-40 fps and will drop to 15-20 overtime. FPS improves when we leave to go out on expeditions

This, I cannot say feels like fps loss as it does more of hitching. I notice it happen on multiplayer and single. It seems to happen over time too and if I logout the game I am playing and go back in (not quit), it seems to be fixed and stays fixed longer though I will test more as I have not been in the game a significant amount of time ofter relogging.

It seems to happen when a large bunch of events happen like chain reaction with multiple trees and items falling and breaking. That can trigger it fast. Or over time when fighting and woodcutting. I notice it begins to happen when I am building and breaking stuff. Almost want to say it feels like a leak but when I remember I will monitor memory usage to confirm. But it does resolve if you logoff the map and go back in.

i get between 5-15 fps regardless of in-game settings, boot file lines, TaskMgr Priority settings, Steam Launch option for fullscreen. nothing changes the FPS at all.

Getting 19-28 FPS
Did not have this issue before the patches.

Things I attempted that resulted in no change or improvement:
Boot config "fix"
Setting valheim to high priority
Adding "-refresh 144 -USEALLAVAILABLECORES -malloc=system -window-mode exclusive" to launch options

CPU: AMD Ryzen 5900X @ 4.174 Ghz
GPU: EVGA RTX 3080 XC3 Ultra
Memory: Corsair Vengeance 32GB 3600mhz CL18

There is absolutely no reason this should be running this bad with the setup I have, especially when less powerful hardware is able to run it way above 60FPS.

If I terraform alot I drop to 60fps and have massive stuttering, but it has to be a huge area flattened

I’ve been studying. One thing I can say for certain is that terra-forming is one of the main culprits. Every single difference in the landscape from the original seed, every building piece placed, every item on the ground, etc. becomes an “instance”. As you move, the game seems to load the original seed and THEN apply these instances (check with F2). It’s not terribly slow with buildings, but the LAND that has been CHANGED causes terrible FPS drops and stutters as the instance count piles up. Needs optimization. I wish it would just save the new instances as a pseudo-seed and not have to apply changes to the original constantly. It’s wonky. Homies and I started a new huge base on flat land and our FPS is smooth. Also done 3 things for smoother performance:
- added the two config lines
- forced steam to run exclusive fullscreen
- started playing with Vulcan

Here’s how to do the first 2:
