@OttawaHacker I managed to stream games from pc to the OPI 5.
What I did was install steam on the orange PI and then stream games from another steam installed in my desktop PC (you can run non steam games this way too)
Basically installed panfork drivers on Orange pi and then installed box64, box86, winex86, winetricks and steam using this script https://github.com/NicoD-SBC/armbian-gaming/tree/main
The only problem I had was that the sound was crackling while streaming games. I read it may be related to the sampling rates and tried to change them to 48khz, but it didn't fix the crackling issue.
If you manage to fix the sound thing, please let me know what you did
Thanks
