GPUs. Launched in 2013, it can be configured to record a continuous buffer, allowing the user to save the video retroactively. ShadowPlay is supported for any Nvidia GTX 600 series card or higher.

Technical details

ShadowPlay can use two capture methods: Frame Buffer Capture (NVFBC) and Inband Frame Readback (NVIFR). NVFBC is used in full screen mode. NVIFR allows the capture of a single window instead of the whole framebuffer. Once ShadowPlay captures a frame, it encodes it using a dedicated GPU hardware accelerated H.264 video encoder that records up to 4K resolution at 130 Mbit/s with minimal performance impact to the rest of the system. The bitrate can be set manually and ranges available depend on user screen resolution.
