Just do what I did. Build a server that runs a Windows VM with GPU passthrough with the intention of using it as your own cloud gaming service, realize the performance is shit because you bought old Xeons with horrendous single-core performance, and give up and just accept that some games won’t be playable because of anticheat. Nvidia please make GeForce Now usable at more than 1080p60 on Linux
Unfortunately I am a creature driven by nostalgia, and I cannot give up certain games. :)
