NVIDIA ShadowPlay vs Special K

NVIDIA ShadowPlay is a free Windows companion app for PC gamers and creators, combining driver updates, game and application optimization, and recording tools in an in-game overlay. Manual recording supports up to 8K HDR at 30 fps or 4K HDR at 120 fps; NVIDIA describes the performance impact as minimal. Automatic Highlights captures key moments, and overlay metrics include FPS, GPU and CPU utilization, FPS 1% Low, and system latency. GeForce RTX 40-series GPU owners can record with AV1 encoding. The app also includes a GPU control center for graphics settings and tuning, Freestyle filters for supported games, and ways to discover and launch selected NVIDIA apps. Requirements include Windows 10 or 11, a GeForce RTX 20, 30, 40, or 50 Series GPU, driver 551.52 or later, 2 GB of system memory, and 600 MB of disk space. Signing in is optional; NVIDIA says login enables users to redeem GPU bundles and rewards.
