Understanding & Fixing Bottlenecks
CPU Bottleneck
Signs: Low GPU usage with high CPU usage, game stuttering.
Fix: Upgrade CPU, close background apps, lower CPU-heavy settings like draw distance.
GPU Bottleneck
Signs: High GPU usage with low CPU usage, low FPS at high settings.
Fix: Upgrade GPU, lower graphics settings, enable DLSS/FSR if available.
RAM & Storage
RAM Issue: Slow loading, system freezes. Fix: Add more RAM (16GB+ for gaming).
Storage Issue: Long load times. Fix: Switch HDD to SSD/NVMe.
Important Notes About Accuracy
No tool is 100% accurate - These results are estimates based on component specifications and typical workloads. Real performance varies by specific games/apps, driver versions, background processes, and cooling solutions.
Bottlenecks are normal - Every system has some bottleneck. Scores under 20% are generally acceptable. The goal is balance, not elimination.
