To optimize your gaming PC for streaming, start by using a powerful CPU (like Ryzen 7 or Intel i7) and a strong GPU to handle both gameplay and encoding. Use a dual-monitor setup to manage your stream easily, and choose a reliable streaming software like OBS Studio. Set your encoder to NVENC (NVIDIA cards) for better performance, adjust your bitrate based on your internet upload speed (usually 4500–6000 kbps for 1080p), and make sure your drivers are up to date. Close background apps, set your game to run in borderless windowed mode, and ensure a stable wired internet connection for smooth, lag-free streaming.
