Based on your PC specifications (Ryzen 5 3600, RTX 3060, 16GB RAM, 650W PSU), it seems unlikely that there is a significant bottleneck causing FPS drops in games. Both the CPU and GPU are relatively powerful and well-balanced components.

However, FPS drops can occur due to various factors, such as software issues, driver problems, background processes, or even thermal throttling. Here are a few steps you can take to troubleshoot and potentially fix the FPS drops:

1. Update Drivers: Ensure that your graphics card drivers are up to date. Visit the Nvidia website to download the latest drivers for your RTX 3060.

2. Monitor Temperatures: Check your CPU and GPU temperatures during gameplay. High temperatures can lead to thermal throttling, causing performance drops. Consider improving airflow in your PC case or investing in better cooling solutions if temperatures are high.

3. Close Background Applications: Make sure no unnecessary applications are running in the background while gaming. Some applications can consume system resources and affect game performance.

4. Adjust Game Settings: Lowering in-game graphics settings can help improve FPS. Experiment with different settings to find a balance between visual quality and performance.

5. Check for Malware: Run a full system scan to check for malware or viruses that might be affecting system performance.

If you continue to experience FPS drops after trying these steps, it may be worth monitoring your system performance using software like MSI
