fpsVR only works if you are also using steamVR OpenXR runtime, which I find highly unstable in my setup.
OXR dev tools “frame timing overlay” is probably the best option you have to be able to see the counter in VR, but its only in one eye and is pretty intrusive visually. Not a long term monitoring option.
I have settled on using MSI Afterburner with RivaTuner statistics server (installs with afterburner). It won’t display the FPS counter in VR (works fine in 2d) but you can set it up so that the FPS counter is in your system tray. Once its in the system tray, you can drag it down and pin it to the bottom bar on your desktop. You have to peek under your headset to see it, but its better for long term monitoring.
