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.

On September 20, an Nvidia forum representative posted a thread to the GeForce forums, stating that the product was being delayed due to a problem with the video formats. It was released in a public beta on October 28, 2013 in the 331.65 driver.
