How to play unsupported Uplay games on Geforce NOW
This tutorial will help you to play Ubisoft games not supported in Geforce NOW, such as Steep or Rayman Legends, using the Uplay launcher.
Requirements: obviously you need to own the game on your Uplay account and the game can't be bigger than 40GB.
1- Search for an Uplay game on Geforce Now (even if you don't own it) and click play.
2- The Uplay login screen will appear, but do not enter your username and password yet. Click on settings, select your language and the "Start Uplay in offline mode"
3-Now enter your username and password and hit login. It should fail and bring you back to the login screen, that´s ok.
4-Now go again to settings, this time untick "Start Uplay in offline mode" option and enter your user and password yet so you can login
5-The Uplay launcher should load, go to your Library and press right click / game details on any Uplay game that is not supported by Geforce Now but you own
6-Where it says game properties select your language (some games don't have that option), click download and once the download is finished you can play
Have fun!
