1. What is Bottleneck Percentage?

The bottleneck percentage measures the performance difference between your CPU and GPU in a gaming system. It shows which component is limiting your overall performance and by how much.

2. How Does the Calculator Work?

The calculator uses the bottleneck formula:

Where:

• \( CPU FPS \) — Frames per second achieved by the CPU
• \( GPU FPS \) — Frames per second achieved by the GPU

Explanation: A positive percentage indicates a GPU bottleneck, while a negative percentage indicates a CPU bottleneck. The higher the absolute value, the more severe the bottleneck.

3. Importance of Bottleneck Calculation

Details: Understanding your system's bottleneck helps in making informed decisions about hardware upgrades and optimizing game settings for better performance.

4. Using the Calculator

Tips: Enter the FPS values your CPU and GPU achieve separately in the same benchmark scenario. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a significant bottleneck?
A: Generally, values above 10% indicate a noticeable bottleneck, while above 20% suggests a significant performance limitation.

Q2: How do I measure CPU and GPU FPS separately?
A: Use benchmarking tools that can measure component-limited FPS, or compare FPS at different resolution/quality settings.

Q3: Is a small bottleneck bad?
A: A small bottleneck (under 5%) is normal and expected in most systems. Perfect balance is rare.

Q4: Can bottleneck percentage change with different games?
A: Yes, different games stress CPU and GPU differently, so bottleneck percentages can vary significantly.

Q5: How can I reduce bottleneck?
A: For GPU bottleneck: lower graphics settings or upgrade GPU. For CPU bottleneck: reduce CPU-intensive settings or upgrade CPU.
