NVIDIA Support:
A full list of system requirements are available on geforcenow.com.
Starting in November 2024, GeForce NOW will no longer support and update the GeForce NOW Windows and macOS apps on legacy operating systems, including Windows 7, Windows 8.1, and macOS 10.11-10.14. If GeForce NOW is already installed on a legacy operating system, you will be unable to update to the latest GeForce NOW app. We recommend using a fully supported operating system to continue playing, not just to have the latest GeForce NOW app updates but also because it may become required to play games on GeForce NOW in the future.
If updating your operating system is not an option, you can try using GeForce NOW from a supported web browser at play.geforcenow.com. Please note that some web browsers may not support the latest versions and security updates on legacy operating systems.
