To optimize a gaming PC for ray tracing in 2025, ensure you're using a high-end GPU like an NVIDIA RTX 40-series or AMD RX 7000-series with updated drivers. Enable DLSS 3 or FSR 3 to boost performance without losing much visual quality. Close background apps, set your game settings to balance quality and performance, and enable hardware-accelerated GPU scheduling in Windows. Also, make sure your CPU and RAM aren’t bottlenecking performance and that your cooling system keeps temps in check during heavy loads.
