Geforce Now is a cloud gaming service that allows users to play games on their low-end devices by streaming them from powerful servers. With Geforce Now, you don't need to worry about your PC specs, as the game is processed on the cloud server, and the video stream is sent to your PC.
In terms of performance, you can expect to play games on Geforce Now with decent graphics settings, even if your PC can't handle the game on its own. However, the quality of your gaming experience may depend on your internet connection. To use Geforce Now, you need a stable internet connection with a minimum speed of 15Mbps. Faster internet speeds will result in smoother gameplay and lower latency.
