- System Lag/Performance Issues: Close unnecessary background applications. Ensure drivers (especially graphics drivers) are up to date. Check for sufficient free space on your 1TB NVMe SSD.
- Overheating: Ensure the PC has adequate ventilation and is not placed in an enclosed space. Clean dust from fans and vents. Monitor component temperatures using software.
