Personally I found the OTT a total faff to use and generally pretty unstable. One of the reasons I’ve gone back to using the virtual desktop wi-fi method is that its generally a bit more stable and consistent. You can’t push parameters as far as you can with the link cable and OTT (when it works!) but at least with the virtual desktop method you can fire up the sim and generally get into VR for a flight.
Having said all of that I find SteamVR and virtual desktop have issues of their own which is why I’ve all but given VR a rest for a while. I’ve got an RTX 3080 and a Ryzen 5 5600X, so a pretty good set up, and there’s still so many performance issues for me.
My line of thinking now is that I’ll come back to VR is 6 months, or certainly when I hear there’s a marked improvement to VR performance and stability consistency. Yeah the potential of VR is amazing but its not the be all and end all of my enjoyment of the sim. Certainly not when I’ve got to spend so long battling with it.
The thing that I’m conscious of are stories here from others that it took years for other flights sims to get stable decent VR performance. Ok they don’t have the full power of Microsoft behind them but even so it shows how cutting edge the tech is.
