NVIDIA ShadowPlay vs PULSE

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.

PULSE is a Windows game performance optimizer that monitors hardware and adjusts system settings. Its free plan provides real-time CPU, GPU, and RAM monitoring, system information, session history, and FPS and frametime readings through separately installed RTSS; no account is required. Pro adds GPU overclocking, CPU tuning, more than 90 persistent tweaks, Live Tune, network tools, per-game profiles, a crosshair overlay, and display controls. Network features include per-app firewall rules, QoS for game traffic, DNS benchmarking, and game-server ping. The maker reports 15–45% more FPS in many CPU-bound games, with results varying by game and hardware and less improvement for GPU-bound titles. PULSE tunes NVIDIA GTX 900 series and newer and AMD RX 400 series and newer, including RDNA 4; Intel Arc is monitored only. Before changing settings, it saves JSON snapshots and says one click restores original values. Requirements include 64-bit Windows 10 version 1809 or later, or Windows 11, and administrator rights for system tweaks. Pro starts at $3.99 a month for the early-supporter monthly plan.
