Struggling with laggy gameplay or frame drops? The battle between your CPU and GPU is often the cause. But does CPU or GPU affect FPS more in gaming? Benchmarks reveal that in CS2, a faster CPU can boost FPS by 20–30%, while in Cyberpunk 2077, a powerful GPU like the RTX 4070 can double performance.
This guide explains how CPU and GPU impact gaming frame rates, shares real-world data, and shows you how to fix bottlenecks using a Bottleneck Calculator. Whether you play Fortnite, CS2, or VR games, you’ll learn how to optimize your system for smoother, lag-free gaming.
CPU vs. GPU: Which Affects FPS More?(Real Data)
The answer to whether CPU or GPU affects FPS more in gaming depends on the type of game and your system settings. Let’s break it down with real-world examples and actionable tips to help you optimize your gaming experience.
1. CPU-Intensive Games
Games like Fortnite, CS2 (Counter-Strike 2), and Valorant rely heavily on the CPU for tasks like physics calculations, AI processing, and managing in-game logic. In these games:
- A weak CPU can cause frame drops or stuttering, even if you have a powerful GPU.
- Overclocking your CPU or upgrading to a faster model can significantly boost FPS and smooth out performance.
Example: In CS2, players often ask, “Does upgrading CPU improve FPS in Fortnite?” The answer is a resounding yes! Benchmarks show that upgrading from a mid-range CPU to a high-end CPU can improve FPS by 20–30%. This is especially true for competitive games where every frame counts.
Pro Tip: If you’re experiencing FPS drops in CPU-intensive games like CS2, consider upgrading your processor or tweaking in-game settings to reduce the load on your CPU.
2. GPU-Intensive Games
On the other hand, games like Cyberpunk 2077, Red Dead Redemption 2, and Hogwarts Legacy push the GPU to its limits with high-resolution textures, advanced lighting effects, and realistic shadows. In these games:
- A weak GPU will result in low FPS, even if you have a top-tier CPU.
- Upgrading your GPU or lowering graphics settings can dramatically improve performance.
Example: In Cyberpunk 2077, switching from an RTX 3060 to an RTX 4070 can double your FPS at 1440p Ultra settings. This makes a huge difference in visually stunning games where immersion is key.
Pro Tip: If you’re wondering, “What’s the best GPU for high FPS in Cyberpunk 2077 at 1440p?” Aim for at least an RTX 4070 or equivalent for smooth gameplay at high settings.
3. VR Gaming: CPU or GPU Intensive?
VR gaming is unique because it’s both CPU and GPU-intensive. Here’s why:
- The GPU handles rendering for two displays (one for each eye), which requires double the graphical power.
- The CPU manages physics, tracking, and AI interactions, ensuring a seamless experience.
For smooth VR gameplay, you need a balanced system with no bottlenecks. A weak CPU can cause stuttering, while a weak GPU can lead to low FPS and a choppy experience.
Example: If you’re asking, “Is GPU more important than CPU for VR gaming?” The answer is that both are crucial. However, in most cases, the GPU has a slightly larger impact on FPS in VR due to the heavy rendering demands.
4. CPU vs. GPU Performance Impact on FPS in Specific Games
Let’s dive deeper into how CPU and GPU affect FPS in specific games:
- Red Dead Redemption 2: This game is heavily GPU-dependent, especially at higher resolutions like 1440p or 4K. However, a strong CPU is still needed to handle the game’s complex AI and open-world mechanics.
- Fortnite: While Fortnite is more CPU-intensive, having a good GPU ensures you can crank up the settings for a more visually appealing experience.
Pro Tip: If you’re unsure whether your system is balanced, use a bottleneck calculator to identify potential issues.
5. How to Optimize FPS in Gaming
Here are some FPS optimization tips to get the most out of your system:
- Upgrade Your Hardware: If you’re playing CPU-intensive games, consider upgrading to a high-end CPU. For GPU-intensive games, invest in a powerful GPU like the RTX 4070.
- Adjust In-Game Settings: Lowering settings like shadows, anti-aliasing, and texture quality can significantly boost FPS.
- Overclock Your CPU/GPU: If you’re comfortable with it, overclocking can squeeze out extra performance.
- Monitor Your System: Use tools like MSI Afterburner to track FPS, CPU usage, and GPU usage in real-time.
Understanding the Roles of CPU and GPU in Gaming
When it comes to gaming, the CPU (Central Processing Unit) and GPU (Graphics Processing Unit) are the two most critical components. But which one affects FPS more in gaming? The answer isn’t straightforward—it depends on the game, your settings, and how these components work together. Let’s break it down in simple terms.
1. What Does the CPU Do?
The CPU is often called the brain of your computer. It handles a wide range of tasks, including:
- Game logic: This includes physics calculations, AI behavior, and in-game mechanics.
- Background processes: Running your operating system, voice chat apps, or streaming software.
- Multi-threaded workloads: Modern games like Cyberpunk 2077 and Fortnite use multiple CPU threads to deliver smoother performance.
While the CPU is crucial, its impact on FPS is often indirect. For example:
- If your CPU can’t keep up with the game’s demands, you might experience stuttering, frame drops, or even high FPS but choppy gameplay.
- Upgrading to a high-end CPU can significantly improve performance in CPU-intensive games like CS2 or Fortnite.
Pro Tip: If you’re wondering, “What’s the best CPU for high FPS in CS2?” Look for processors with strong single-core performance, like the AMD Ryzen 7 7800X or Intel Core i7-13700K.
2. What Does the GPU Do?
The GPU is the powerhouse behind your game’s visuals. It handles tasks like:
- Graphics rendering: Creating textures, shadows, and lighting effects.
- Resolution scaling: Delivering crisp visuals at 1080p, 1440p, or even 4K.
- Ray tracing: Advanced lighting effects in games like Alan Wake 2 and Hogwarts Legacy.
The GPU has a direct impact on FPS, especially in graphically demanding games. For example:
- If your GPU is underpowered, you’ll notice lower FPS even at medium settings.
- Upgrading to a powerful GPU like the RTX 4070 can double your FPS in games like Cyberpunk 2077 at 1440p Ultra settings.
Pro Tip: If you’re asking, “What’s the best GPU for ray tracing in Alan Wake 2 at 1440p?” Go for NVIDIA’s RTX 40-series cards for the best performance.
How to Find Bottlenecks in your System: A 3-Step Guide
Wondering if your CPU or GPU is holding you back? Here’s a simple guide to identify and fix bottlenecks:
Step 1: Use a Bottleneck Calculator
A Bottleneck Calculator is the easiest way to identify which component is limiting your performance. Here’s how to use it:
- Enter your CPU, GPU, and RAM specs.
- Select the game you want to analyze (e.g., Fortnite, CS2).
- Check the results to see if your CPU or GPU is the bottleneck.
Pro Tip: Use tools with high accuracy, like our PC Build Bottleneck Calculator, which matches real-world performance in 95% of tests (User Benchmark).

Step 2: Run Benchmarking Tools
Tools like MSI Afterburner or NVIDIA FrameView can measure real-time performance:
- Monitor CPU/GPU usage and FPS while gaming.
- If your CPU usage is near 100% while GPU usage is low, your CPU is the bottleneck.
- If your GPU usage is maxed out but CPU usage is low, your GPU is the bottleneck.
Pro Tip: Test both CS2 (CPU-heavy) and Cyberpunk 2077 (GPU-heavy) to see where your system struggles.
Step 3: Adjust Settings and Retest
Once you’ve identified the bottleneck, tweak your settings for better performance:
- For CPU bottlenecks: Lower settings like physics quality, draw distance, or AI complexity.
- For GPU bottlenecks: Reduce resolution, shadows, or ray tracing effects.
Pro Tip: If you’re experiencing FPS drops in GPU-intensive games like Hogwarts Legacy, upgrading your GPU or lowering settings can make a huge difference.
Balancing CPU and GPU for Optimal Gaming Performance
To achieve the best gaming performance, you need a balanced system where neither the CPU nor the GPU is holding the other back. Here’s how to ensure your system is optimized:
- Upgrade Strategically: If you’re playing CPU-intensive games like CS2, invest in a high-end CPU. For GPU-intensive games like Cyberpunk 2077, prioritize a powerful GPU like the RTX 4070.
- Monitor Performance: Use tools like MSI Afterburner to track CPU/GPU usage and FPS in real-time.
- Adjust Settings: Fine-tune in-game settings to reduce the load on your bottlenecked component.
By understanding the roles of CPU and GPU and how they affect FPS, you can make smarter upgrades and enjoy smoother, more immersive gaming experiences. Happy gaming! 🎮
