The GeForce Experience (GFE) client installer does not include a database of supported games. After the GeForce Experience is initially installed, it will attempt to download a database containing a list of supported games. Firewall programs may prevent the GFE client from downloading the latest database in which case the client will not be able to detect any of your installed games. Please make sure the GeForce Experience is able to connect to the internet after it has been installed.
GeForce Experience (GFE) 客户端安装程序不包含受支持游戏的数据库。初始安装 GeForce Experience 后，它会尝试下载包含支持游戏列表的数据库。防火墙程序可能会阻止 GFE 客户端下载最新的数据库，在这种情况下，客户端将无法检测到任何已安装的游戏。请确保 GeForce Experience 安装后能够连接到互联网
