🎮 What Is a GPU Bottleneck?

A GPU bottleneck occurs when the graphics card reaches maximum capacity while other components—like the CPU—still have unused performance. This leads to:

• Low or unstable FPS

• High GPU usage (95–100%) consistently

• Poor performance in graphically intensive games

• Lag during high-resolution gameplay

• Lower benchmark scores compared to expectations

---

⚠️ Signs You Have a GPU Bottleneck

• 🔥 100% GPU usage while CPU remains under 50%

• 🎮 FPS drops during high-resolution gaming (1440p / 4K)

• 🖥 Stuttering during cutscenes

• 📉 Lower-than-expected benchmark results

• 🌡 GPU temperatures are very high due to constant load
