NVIDIA Corporation (NASDAQ:NVDA) has announced G-SYNC technology and ShadowPlay game-capture software. The G-SYNC technology enables synchronization between the GPU and the display. ShadowPlay is a tool that lets players capture game footage, which will be available October 28th with version 1.7 of the GeForce Experience software.
ShadowPlay requires the GeForce GTX 600 series and adobe. Those GPUs feature an on-board H.264 video encoder. The software can record footage at 60 frames per second in 1080p with a performance hit of between 5-10%. ShadowPlay records a buffer of the last 10 to 20 minutes of gameplay. It generates a video file only when you ask. ShadowPlay generates standard MP4 files so that it can be uploaded to YouTube and other video websites.
G-SYNC will solve the problem of on-screen lag and stuttering. G-SYNC synchronizes the monitor refresh rate to the GPU render rate so images display the moment that they are rendered. The objects are sharper and game play is smoother.
Displays typically have fixed refresh rates, which is typically 60 times a second (hertz). GPUs render frames at different rates due due to various gaming requirements.
“Our commitment to create a pure gaming experience led us to G-SYNC,” stated Jeff Fisher, a senior vice president at the GeForce business unit at NVIDIA. “This revolutionary technology eliminates artifacts that have long stood between gamers and the game. Once you play on a G-SYNC monitor, you’ll never want to go back.”
By turning on V-SYNC (Vertical-SYNC) it will eliminate tearing, but causes increased lag and stutter as the GPU and monitor refresh at different rates. G-SYNC enables gamers to eliminate this tradeoff. It syncs the monitor to the GPU, regardless of frame rate.
