Warzone is more CPU intensive than many games, but it also demands strong GPU performance. Smooth gameplay needs a balanced CPU and GPU, with at least six cores recommended for handling Warzone’s large maps and heavy graphics.
In this detailed guide, you’ll find explanations, benchmarks, optimization strategies, and hardware recommendations—all made easy to read and implement.
CPU vs GPU: Roles in Gaming Performance
At its core, the CPU (Central Processing Unit) handles game logic, AI, physics, and matchmaking calculations, while the GPU (Graphics Processing Unit) renders textures, lighting, models, and visuals.
Most gaming guides agree Warzone leans heavier on the GPU, but its engine—especially in early matches or crowded areas—can stress the CPU significantly.
A weak CPU in those scenarios can bottleneck the system, leaving your powerful GPU underutilized.
Warzone System Requirements (2025 Update)
Here’s how the system specs stack up:
| Tier | CPU Requirement | GPU Requirement | RAM |
| Minimum | Intel i5-4690 / Ryzen 3 1200 | GTX 1060 / RX 480 | 8 GB |
| Recommended | Intel i7-8700K / Ryzen 7 3700X | RTX 2070 Super / RX 5700 XT | 16 GB |
These specs show that both components are necessary for a smooth experience, but the GPU requirement is notably stronger.
Is Warzone More CPU or GPU Intensive?
If we boil it down:
- GPU remains the backbone, especially at high resolutions and ultra settings, but the CPU can become the weak link if it can’t manage the complexity of large-scale battles.
- In crowded areas or early-game phases, Warzone’s engine demands rapid physics and logic calculations—tasks reliant on CPU performance.
So, the real answer: Warzone is both CPU and GPU intensive—but the CPU often determines whether your GPU can perform at its peak.
Benchmarks & Real-World Usage
One tester using MSI Afterburner observed their GPU was at 97% usage, whereas the CPU was around 57% during 1080p gameplay—highlighting the GPU-intensive nature at typical resolutions.
Yet others report that Warzone (and Warzone 2) becomes more CPU bound—especially in high player-density scenarios—due to its AI, physics, and logic processing demands.
Optimization Tips for Better Performance
To balance CPU and GPU load effectively:
For CPU:
- Close unnecessary background apps to reduce load.
- Lower draw distance and AI-heavy settings.
- Ensure your CPU meets or exceeds recommended specs.
For GPU:
- Increase resolution or texture quality (shifts load towards GPU).
- Keep graphics drivers up to date.
- Use GPU-centric enhancements like DLSS/FSR if available.
These adjustments can help shift the workload balance and reduce bottlenecks.

Is Warzone 3 CPU or GPU Intensive
Warzone 3, like previous versions, puts more pressure on the GPU for graphics but also requires a strong CPU for smooth gameplay.
The GPU handles textures, shadows, and resolution, while the CPU manages game logic, physics, and player actions.
At higher resolutions like 1440p or 4K, the GPU usually becomes the main bottleneck, but weak CPUs can still limit frame rates in crowded or competitive matches.
Is Warzone 2 CPU or GPU intensive
Warzone 2 is both CPU and GPU intensive, but it depends on your settings. At 1080p, the CPU often becomes the limiting factor, handling players, AI, and physics across large maps.
At higher resolutions like 2K or 4K, the GPU workload increases because of detailed textures and shadows.
A balanced system with a strong CPU and GPU ensures smoother performance and helps avoid bottlenecks during gameplay.
Is Fortnite CPU or GPU intensive
Fortnite leans more toward being GPU intensive since graphics rendering, shadows, and effects rely on your graphics card.
However, Fortnite also depends on the CPU for tasks like player movement, building mechanics, and handling large lobbies.
At lower settings, the CPU might be the limiting factor, but at high resolutions, the GPU does most of the work. For best performance, a balanced CPU and GPU setup is ideal.
Is COD more CPU or GPU intensive
Call of Duty games generally stress both the CPU and GPU, but the GPU usually carries the heavier load for rendering detailed environments and effects.
The CPU, however, is critical for smooth multiplayer gameplay because it processes AI, physics, and player actions.
At lower resolutions, COD can feel more CPU heavy, while at higher settings and resolutions, the GPU becomes the main bottleneck for performance.
Is COD BO6 CPU or GPU intensive
Call of Duty Black Ops 6 (BO6) is mostly GPU intensive since modern graphics engines rely heavily on powerful GPUs for visual effects, shadows, and ray tracing.
However, the CPU still plays a big role in handling AI, physics, and multiplayer calculations. If the CPU is weak, you may face stutters and low FPS even with a strong GPU. Ideally, gamers should use balanced hardware for the best experience.
Warzone 100% CPU usage
If Warzone shows 100% CPU usage, it means the processor is overloaded, often due to large lobbies, background apps, or poor optimization.
This problem can cause stuttering, FPS drops, or even crashes. To fix it, reduce CPU-heavy settings like draw distance, close unnecessary apps, and check for driver or game updates.
Ensuring your CPU meets recommended requirements helps balance workload and reduce constant maxed-out usage during gameplay.
Warzone CPU vs GPU utilization?
Warzone uses both the CPU and GPU, but utilization depends on resolution and settings. At 1080p, the CPU is often stressed more since the GPU finishes tasks quickly.
At 1440p or 4K, the GPU utilization climbs because rendering becomes heavier. Ideally, you want both CPU and GPU running close to 80–90% for balance. If one is underused, bottlenecks occur, leading to FPS issues or performance drops.
Warzone using CPU instead of GPU
If Warzone seems to use the CPU instead of the GPU, it usually means the game isn’t detecting your graphics card properly.
Common causes include outdated drivers, wrong display settings, or the GPU not being selected as the primary device.
You can fix this by updating drivers, forcing Warzone to use the dedicated GPU in Windows settings, and checking power options. Once fixed, performance improves significantly.
Warzone 2 Low GPU/CPU Usage 5900x RX 6900XT
Players with powerful setups like Ryzen 9 5900X and RX 6900XT may see low GPU or CPU usage in Warzone 2.
This often happens because of software bottlenecks, poor optimization, or in-game settings not fully stressing the hardware.
Sometimes, the CPU can’t keep up with GPU capacity, leading to reduced usage. Updating drivers, enabling high-performance mode, and adjusting settings can help unlock the full potential of your system.
100% CPU usage Modern Warfare, Warzone
If Modern Warfare or Warzone pushes the CPU to 100%, it usually signals a bottleneck or background tasks eating resources.
The game’s large maps and physics can overwhelm weaker CPUs. To fix it, lower CPU-heavy settings, disable background programs, and update BIOS or drivers.
High CPU usage without GPU bottlenecking often causes stuttering and poor frame rates, so balancing system resources is key for smooth gaming.
Warzone 2.0 and GTA V—CPU and GPU capped at 50%?
When both Warzone 2.0 and GTA V show CPU and GPU capped around 50%, it’s often a sign of system limitations or settings mismatch.
This can happen if V-Sync or frame limiters are on, restricting performance. It may also occur due to low-resolution settings where neither CPU nor GPU is fully stressed.
Disabling caps, raising settings, and ensuring drivers are updated usually helps maximize hardware usage properly.
