GeForce 461.09 Driver was installed on my pc last night and my Rift S stopped displaying, Just simply uninstall GeForce Experience and the driver, and reinstall GeForce Experience (this is what i did) if you get a error code just trying to load into GeForce Experience that says something like try restarting your pc or something like that, Its not gonna do anything restarting. I reinstalled GeForce and it works perfect now. If you need help just reply
