The Truth About Tarkov Use Only Physical Cores: Does It Actually Boost FPS In 2024?

The quest for a stable frame rate in Escape from Tarkov is a journey every player knows too well. Despite its breathtaking realism and unmatched tension, the game is notorious for its optimization challenges, often leaving even high-end PC owners scratching their heads. One of the most debated solutions in the community is the tarkov use only physical cores setting found deep within the game’s graphics and game options.

Many players report an immediate jump in smoothness and responsiveness, while others claim it does nothing for their specific hardware. In a game where a single frame drop can mean the difference between a successful extraction and a total loss of gear, understanding how your CPU interacts with the Unity engine is vital. This guide explores the technical reality behind this setting and whether you should enable it for your specific setup.

Why Tarkov Use Only Physical Cores is the Most Popular Performance Fix

The primary reason why tarkov use only physical cores remains a trending topic in the community is the way Escape from Tarkov utilizes processor resources. Unlike many modern titles optimized for high core counts, Tarkov is heavily dependent on single-core performance and the speed of your primary CPU threads.

Most modern processors use technologies like Intel’s Hyper-Threading or AMD’s SMT (Simultaneous Multithreading). These technologies allow a single physical core to act as two "logical" cores or threads. While this is fantastic for video editing or multitasking, it can sometimes confuse older game engines. When Tarkov tries to spread its workload across these logical threads, it can lead to "scheduling" conflicts, resulting in the dreaded micro-stutters that plague the Streets of Tarkov map.

By enabling the tarkov use only physical cores toggle, you are essentially telling the game to ignore those virtual threads and focus all its data processing on the "real" hardware cores. For many, this creates a more consistent delivery of frames, even if the maximum FPS doesn't skyrocket.

How to Correctly Enable the Tarkov Use Only Physical Cores Setting

Activating this feature is straightforward, but there are a few nuances you should be aware of to ensure it actually takes effect. To find the setting, navigate to the Settings menu within the Tarkov launcher or the main in-game screen and look under the Game tab.

Once you check the box for tarkov use only physical cores, it is widely recommended to restart your game. While the game claims to apply changes instantly, many veteran players have noted that the CPU affinity (the technical term for which cores the game uses) doesn't always reset properly until a fresh launch.

It is also important to note that this setting works in tandem with the Automatic RAM Cleaner. If you are running an older system with 16GB of RAM or less, enabling both can provide a significant boost to system stability during long gaming sessions. However, the focus remains on the CPU, as that is the primary bottleneck for most Tarkov players.

SMT vs. Hyper-Threading: Why Unity Struggles with Logical Cores

To understand why the tarkov use only physical cores option exists, we have to look at the Unity Engine. Tarkov runs on a version of Unity that has historically struggled with efficient multithreading. In a perfect world, a game would distribute its load evenly across every available thread.

In reality, Tarkov has a "main thread" that handles most of the heavy lifting, including AI calculations, ballistics, and player movement. When this main thread is assigned to a logical core (a virtual thread) rather than a physical one, it has to share the physical core's resources with another process. This "resource sharing" creates a latency penalty.

When you utilize tarkov use only physical cores, you are giving the game's main thread exclusive access to the CPU's hardware. This reduces the time it takes for the CPU to communicate with the GPU, leading to a more "connected" feeling when aiming and moving. This is why players with high-end CPUs often feel the game is "snappier" after making this adjustment.

Process Lasso vs. In-Game Settings: Which Method Offers More Stability?

If you spend any time in the competitive Tarkov scene, you will likely hear about a program called Process Lasso. This is a third-party power-user tool that allows for much more granular control over your CPU than the built-in tarkov use only physical cores checkbox.

Many players find that the in-game setting can be "buggy." Sometimes it resets after a patch, and sometimes it simply fails to engage correctly. Process Lasso allows you to permanently set the "CPU Affinity" for the EscapeFromTarkov.exe process. By manually disabling SMT or Hyper-Threading for the game via this tool, you ensure that the game only ever sees physical cores.

However, for the average user, the internal tarkov use only physical cores setting is usually sufficient. Using third-party tools adds a layer of complexity and another background process to manage. If you are seeing a noticeable improvement with the in-game toggle, there is likely no need to dive into complex software configurations.

The Impact of Tarkov Use Only Physical Cores on AMD Ryzen and Intel Processors

The effectiveness of this setting often depends on which brand of CPU is sitting in your motherboard. AMD Ryzen users, particularly those on the older 3000 and 5000 series, often report the most significant gains from using tarkov use only physical cores. This is due to the way AMD’s Core Complex (CCX) architecture handles data sharing between cores.

On the other hand, Intel users with newer "Hybrid Architecture" CPUs (like the 12th, 13th, or 14th Gen i7 and i9) face a different challenge. These CPUs have P-Cores (Performance) and E-Cores (Efficiency). For these users, the tarkov use only physical cores setting is vital to ensure the game doesn't accidentally run on the slower E-Cores, which would cause a massive drop in performance.

If you are using an AMD X3D processor, such as the 7800X3D, you might find that the tarkov use only physical cores setting has a smaller impact. This is because the massive L3 V-Cache on those chips helps mitigate the latency issues that the setting is designed to fix. Regardless of your hardware, benchmarking your FPS in an offline raid with and without the setting is the only way to be 100% sure of its impact.

Common Myths and Performance Bugs When Disabling Logical Cores

There are several misconceptions surrounding the tarkov use only physical cores option. One common myth is that it will make your CPU run hotter. In reality, disabling logical threads usually decreases CPU temperature slightly because the processor is doing less simultaneous work on each physical core.

Another common issue is that players expect this setting to fix network-related lag. It is important to distinguish between "low FPS" and "desync." While tarkov use only physical cores can help with the smoothness of your local client, it will not fix poor server performance or high ping.

Lastly, some players report that the setting causes the game to crash on startup. If this happens, it is usually a sign of an unstable CPU overclock. When the game is forced to use only physical cores, it puts a more direct and intense load on those specific parts of the silicon, which can expose an unstable voltage setting.

Fixing Micro-Stutters and Frame Drops in Escape from Tarkov

While tarkov use only physical cores is a powerful tool, it is just one piece of the optimization puzzle. To truly eliminate stutters, you must look at your entire system. Tarkov is incredibly RAM-intensive, and many players find that upgrading from 16GB to 32GB of high-speed memory is the single best thing they can do for performance.

Additionally, ensuring that your Page File is located on a fast NVMe SSD can prevent the "freezing" that occurs when the game has to swap data from memory to your drive. When combined with the tarkov use only physical cores setting, these hardware tweaks create a much more stable environment for the Unity engine to operate.

Don't forget to check your Nvidia Control Panel or AMD Radeon Settings as well. Setting "Power Management Mode" to "Prefer Maximum Performance" ensures that your CPU and GPU don't downclock during the middle of a raid, which can cause sudden frame drops even if the physical cores setting is enabled.

Does the Unity 2021 Update Change the Need for This Setting?

As the developers at Battlestate Games continue to update the game’s engine—most notably the transition to Unity 2021—many wonder if tarkov use only physical cores will eventually become obsolete. Newer versions of Unity have better native support for multithreaded rendering and improved job systems.

However, based on current testing within the community, the "main thread bottleneck" still exists. Until the game undergoes a massive architectural shift in how it handles AI and physics, the physical core limitation will likely remain a relevant fix. It is always a good idea to re-test this setting after every major technical patch or "Wipe," as the game’s performance profile changes frequently.
