You can already use the GeForce Experience with the Windows 8.1 update

GeForce Experience 1.5.1 has been supported by Windows 8.1, and minor improvements have been made, such as a reduction in conflicts due to conflicts, improved stability, and a specific issue.

For those unfamiliar with the program, the application automatically maps the hardware and software environment and then adjusts the graphics quality of the games accordingly. The stuff strives for the best possible visual quality, but of course it also pays attention to speed. The best speed is usually guaranteed with the latest driver, which can be downloaded with one click using the GeForce Experience. 

The program does not support Windows XP, in addition, we must have at least one GeForce 400 card to get game-related optimizations.
