Well it is bad user experience. While GeforceNow allos me to connect my steam and epic account, the list of games actually playable is not my collection there, but the subset of games nvidia has a licensing deal (a lot less). Also they are free to remove support for games - as happened when big players withdrew their licensing.

I've seen tech videos from LTT and alike where they build remote gaming rigs using windows Hyper-V with GPU passthrough to the guest - that is essetially what they should do, and let me rent a virtual machine with hardware support and low latency video compression. I don't see a reason you would need any licensing deals there.
