I'd also avoid using OpenVR, as it uses SteamVR, and it is buggy with iRacing. I prefer the Oculus setting in iRacing, but also tried with OpenXR. No matter what I choose, I get a similar error message. I tried disabling upscaling as you suggested in the linked ticket, but it did not help. Then I enabled it and disabled foveated rendering. Same error, see the two logs, both with Oculus setting.
Virtual Desktop is not an option for me as I don't have good enough WiFi, and I also prefer wires (through QuestLink) to minimize latency. VD doesn't work wired.

I have a very similar issue to this, maybe the same: https://github.com/fholger/vrperfkit/issues/126 iRacing starts on the monitor but it stucks on the loading screen inside Quest 3.
I'd also avoid using OpenVR, as it uses SteamVR, and it is buggy with iRacing. I prefer the Oculus setting in iRacing, but also tried with OpenXR. No matter what I choose, I get a similar error message. I tried disabling upscaling as you suggested in the linked ticket, but it did not help. Then I enabled it and disabled foveated rendering. Same error, see the two logs, both with Oculus setting.
Virtual Desktop is not an option for me as I don't have good enough WiFi, and I also prefer wires (through QuestLink) to minimize latency. VD doesn't work wired.
System: Win 11 Pro 22H2, Quest 3 update 59, AMD 7900X CPU, NVidia 4070.
