Forcing specific framerate

[TAsmund]

Developing in Unity 2022 using the Wave SDK (not OpenXR).

I need our application to run at the lowest available framerate, so I use the interop WVR_GetAvailableFrameRates to get the available framerates, then set it with a call to WVR_SetFrameRate(lowestFrameRate);

What is the difference between doing that, and setting the framerate through Unity with Application.targetFrameRate = (int)lowestFrameRate;

Should I do both? Or is Application.targetFrameRate ignored?

Hi @TAsmund,

It is stated in above link.

Thank you for reply.

My question was about the Wave driver interop call: WVR_SetFrameRate

which is explained on this page
https://hub.vive.com/storage/docs/en-us/WVR_SetFrameRate.html

How does that work together with Application.targetFrameRate?

You're asking this question is it because you call Application.targetFrameRate and it doesn't print what you are expected?

Using  WVR_SetFrameRate seems to work, I was just wondering if just calling  WVR_SetFrameRate is the correct way to set framerate, or if Application.targetFrameRate should also be set?

Hi @TAsmund,

According to your result, calling WVR_SetFrameRate works.

And, according to below statement, VR platforms ignore both QualitySettings.vSyncCount and Application.targetFrameRate.

I don't think you will need to set Application.targetFrameRate.

Thank you so much for clarifying this!
