low fps and all cores below 80%

[Hypersuperguy]

I have a 13700k and 3090ti and I am trying to play the game at the highest render distances. I am only getting around 20fps despite having all 16 cores enabled in the launcher option. no thermal or power throttling is happening so I don't know how to get rid of the bottleneck

Are you playing in a server? Is there a ton of mods loaded?
Some servers are scripted poorly and cause this. If sp, try lowering the view distance.. it sucks but, you want better frames.
Also, if you're not on the "profiling branch" try that to see if your frames increase.. it did mine, and I only have a Ryzen 7 2700 3.2ghz 8 core cpu.

what's profiling branch? also I'm using campaign as the benchmark so that is where it is happening

Go into the Arma property settings and change the "beta" program to the Profiling Branch

Enabling all 16 cores doesn't mean anything. That isn't how software coding works unfortunately. Certain tasks in a videogame have to be completed by a single thread and so single-thread speeds will always be the limiting factor. This game also isn't GPU-bound as it doesn't use DX12 or Vulkan which has more GPU focused performance.

This game in addition to being limited by single-core speeds like every game is eventually, also has very poor multi-threading because it's literally almost 12 years old. Async functions and such were not common back then compared to today. Hence why they've made a new game engine to take advantage of modern tech. Your 16 cores aren't all being used, and you don't need to specify them anyway as the game auto-detects what you have fine.

TLDR:
As was suggested, profiling branch may help you.

The other additional thing you can do is add the mimalloc memory allocator instead of the default one, helps some people. https://github.com/GoldJohnKing/mimalloc/releases

If you are getting 20 fps with the base game campaign, something is wrong.

Look at how old the game is. It is using the single core, though there is partial multithreading in that performance branch. Reduce rendering distance. It is an old, but very good game.

I’m worried it’s a hardware issue. I wrote in parameters that there are 16 cores so it should be using them all.

That's not how it works. The game is a multi thread game, but it does most processes in a single core.

Arma 3 it only uses 1 core realistically. Most of the hard processing is done on 1 core.
The game is limited by the engine, so the bottleneck is the game's engine.
Highest render distances means tons and tons of calculations for CPU to do, it spends more time to calculate than render the frames.

Hiddes the AI when you arent looking at their direction to save some calculations on CPU.

What does this mod do?
In short, this addon replaces dead bodies located far from players with simple object (right now - a body bag). When players approach the simple object, it is again replaced with that same body and every item and weapon on it.
Best solution so far:
Lossless Scaling steam app:
https://store.steampowered.com/app/993090/Lossless_Scaling/
Is a 3rd party app that acts like DLSS, frame generator etc...

Arma3 uses 1 core for the majority of its functions and is the reason they built a new engine for Reforger. The setting imply you can utilize more, but if you monitor your cpu you will see only 1 is really cranking. That said, 20 fps in sp is well below normal.

what's sp?

Arma is the great equalizer

They can resell user created mods as their own but not optimise the game .

What mods are being sold?

The game is optimized, do you mean further improving multi threading, because they are working on that right now.
