How to Fix Apex Legends High CPU Usage on PC: Complete Troubleshooting Guide

Quick Answer

High CPU usage in Apex Legends on PC is most commonly caused by uncapped frame rates, outdated GPU drivers, incorrect in-game settings, or background processes competing for CPU resources - each has a specific fix that reduces load and improves frame consistency.

Why Apex Legends Uses So Much CPU

Apex Legends is a CPU-intensive battle royale title that relies heavily on single-threaded performance for game logic, hit registration, and netcode processing. Unlike GPU-bound titles where your graphics card is the limiting factor, Apex can saturate CPU cores even on mid-range gaming hardware, particularly when frame rates are uncapped. Running Apex without a frame rate cap tells the engine to render as many frames as possible, which pushes both CPU and GPU to maximum utilization continuously - this is intentional behavior but causes heat and noise issues on many systems.

For South African players on Ryzen 5 or Core i5 platforms - the most common gaming CPU tier in the local market - high CPU usage manifests as frame time spikes and occasional stutters rather than a sustained low FPS, because the processor periodically cannot service both game logic and rendering demands simultaneously. Understanding this distinction helps you apply the right fix rather than chasing settings changes that do not address the root cause.

Fixing High CPU Usage: Frame Rate Cap and Settings

The most effective single change for reducing Apex Legends CPU usage is capping your frame rate. Set a frame rate limit in Apex's video settings equal to your monitor's refresh rate - if you have a 144Hz display, cap at 144 FPS. This prevents the game from rendering unnecessary frames beyond what your monitor can display and dramatically reduces both CPU and GPU load. The improvement is often immediately visible in task manager and CPU temperature readings.

Additionally, enabling NVIDIA DLSS or AMD FSR within Apex shifts more rendering work to the GPU's dedicated upscaling hardware, reducing the per-frame burden on the CPU. Set Texture Streaming Budget to match your GPU VRAM to prevent the CPU from having to manage frequent texture swaps. Ragdolls and impact marks can be reduced or disabled in advanced settings - these physics and persistent visual effects are CPU-calculated and contribute meaningfully to frame time budgets during high-action moments in the game.

Driver Updates, Background Processes, and System Configuration

Outdated GPU drivers are a frequently overlooked cause of high CPU usage in Apex Legends. When the GPU driver is not efficiently communicating with the game engine, the CPU has to do additional work compensating for driver inefficiencies. Keep your GPU drivers current - specifically check for driver updates after major Apex game patches, as new driver versions are often released in coordination with game updates to address compatibility issues.

Background processes competing with Apex for CPU resources are another common culprit for South African players. Antivirus real-time scanning, Windows Update service, cloud backup applications, and browser processes all consume CPU cycles that Apex needs. Before gaming sessions, close unnecessary background applications and check Task Manager's CPU column sorted by usage. Temporarily disabling Windows Defender real-time protection during gaming (re-enable afterward) can yield noticeable frame time improvements on systems where AV is aggressively scanning game files during play.

Frequently Asked Questions

Q: Why is Apex Legends using 90 to 100 percent of my CPU?

A: An uncapped frame rate is usually the primary cause. Set a frame rate cap at your monitor's refresh rate in Apex's video settings. Also close background applications and check for outdated GPU drivers if the issue persists after capping frames.

Q: Does setting a frame rate cap hurt my performance in Apex Legends?

A: No - capping at your monitor's refresh rate (144 FPS for a 144Hz monitor, for example) means you are not sacrificing frames you can actually see. It reduces CPU and GPU heat and can actually improve frame time consistency, which feels smoother than uncapped gameplay with occasional spikes.

Q: Will upgrading my CPU fix high CPU usage in Apex Legends?

A: Upgrading to a faster CPU helps if your current processor is genuinely too slow for the task, but software fixes like frame capping and driver updates often resolve the issue without hardware changes. Try the software solutions first before committing to a CPU upgrade.
