Nvidia just announced that the GeForce NOW Beta is available for macOS in Europe.
GeForce NOW lets you stream games onto Mac with the heavy lifting being done on the cloud. With over a 100 supported games right now in Beta, more will be added at regular intervals. PUBG is supported for those interested. Check to see if your Mac can run the client here.
You can join the beta by registering and downloading the GeForce NOW app and selecting games through Steam and Battle.net that are owned. Internet connections of 25Mbps are minimum with a 50Mbps connection recommended for game streaming.
The streaming happens from a dedicated virtual GeForce NOW machine with a GTX 1080 card. The full list of supported games is here.
