The Steam Deck is a popular handheld gaming device that, while affordable and visually impressive, faces limitations in running demanding games. Nvidia's GeForce Now has released a dedicated app for the Steam Deck, improving the gaming experience by allowing access to high-quality titles without the need for complex setup. The app enhances battery life, enabling four to five hours of gameplay compared to two hours with native 3D games. It supports resolutions up to 4K and 60 fps with an Ultimate subscription, although it is limited compared to the PC version. The Steam Deck can access games from various platforms, including Xbox, Epic Games Store, and GOG, with GeForce Now simplifying this process. The app requires a minimum internet speed of 45 Mbps for optimal performance and offers different subscription tiers, with the free version having session limits and resolution caps.
