Nvidia ShadowPlay is a hardware accelerated screen recording utility for Windows PCs using GeForce GPUs, made by Nvidia Corp as part of its GeForce Experience software. It can be configured to record continuously a time behind, allowing the user to save the video retroactively. ShadowPlay is supported by GTX 650 and higher series desktop graphics cards.
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 is used in window mode only because has a higher performance impact.
Once ShadowPlay captures a frame, it encodes it using the dedicated GPU hardware.
Release
ShadowPlay was set to release at the same time as the Nvidia Shield (June 2013) but was delayed and was pushed to being released during the summer of 2013 but was postponed again.[citation needed] On the 20th of September, 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.
