Quick Vive Question - Which frames dropped if fps > 90?

Quick theoretical question. I have a 120hz monitor, so I set my project fps to 120fps. The openvr top should max out at 90fps. What happens to the extra frames? Are they dropped? Interpolated? I’m assuming any frames ready before the top is ready to upload to the vive again are dropped, but this implies that there would be uneven or slightly jerky movement of objects moving quickly?

In practice, I haven’t seen anything that looks odd. Just curious about the pipeline if anyone knows.

I think the OpenVR library will throttle us if we try to run higher than 90fps, so your project shouldn’t be able to reach 120fps. You’ll see longer cook times in the OpenVR TOP as it throttles us.

Thanks! I realized I was seeing >90 fps in the project after I added animation but before I added the Vive render setup.

Interesting note for anyone else reading the thread, the project is capped to 90 even if there isn’t an openvr top and you’re only pulling sensor data from the sensor chop. Makes sense, but just something to keep in mind.
