With each new architecture over the past three generations, NVIDIA toyed with display sync. With "Kepler" it introduced Adaptive V-Sync, by the time "Maxwell" came along, you had G-SYNC, and with "Pascal," the company is introducing a new feature called Fast Sync. NVIDIA states that Fast Sync is a low-latency alternative to V-Sync that eliminates frame-tearing (normally caused due to GPU's output frame-rate being above the display's refresh-rate); while letting the GPU render unrestrained from V-Sync, thereby reducing input latency. This works by decoupling the render output and display pipelines, allowing excessive rendered frames to be temporarily stored in the frame-buffer. The result is you get enjoy both low input-lag (from V-Sync "off") and no frame-tearing (from V-Sync "on"). You will be able to enable Fast Sync for any 3D App by editing its profile in NVIDIA Control Panel, and forcing Vertical Sync mode to "Fast."
