Hey guys,

I am trying to set refresh rate on Quest 3 using that command :
Unity.XR.Oculus.Performance.TrySetDisplayRefreshRate(newRate)

But on UNity 2022 LTS with Oculus XR plugin 4.1.1, I get an error at runtime :
DllNotFoundException: Unable to load DLL ‘OculusXRPlugin’. Tried the load the following dynamic libraries: Unable to load dynamic library ‘OculusXRPlugin’ because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen failed: library “OculusXRPlugin” not found

I do not have this error when using an older project with Oculus XR plugin 3.x.
Anyone knows why this happens, and ultimately how to solve it ?
Config is :
Unity 2022.3.11f1
XR Plugin management 4.4.0
Unity OpenXR Meta 1.0.0
Open XR Plugin 1.8.2
Oculus XR plugin 4.1.1

Same here!

DllNotFoundException: Unable to load DLL ‘OculusXRPlugin’. Tried the load the following dynamic libraries: Unable to load dynamic library ‘OculusXRPlugin’ because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen failed: library “OculusXRPlugin” not found.

There is a slightly newer version of the Oculus package available. Try updating to version 4.1.2 and if the problem persists you may need to remove the Oculus package, restart Unity and re-install the package. Likely the dll isn’t copying correctly due to a metadata issue in your project and resetting the metadata with a removal and restart should resolve the issue.

Hello @Ed_unity , I have tried as you indicated but I still get the same issue.
Are there some temp files to delete aside from just deinstalling the package and reinstalling after unity restart ?
Or is the syntax different now ?
Thank you

Hey @Ed_unity , if I remove the package, then delete the library folder and reopen my project, then re-install package, is this a guarantee that the environment will be clean and then I can try again ?
Thanks

Hey guys and @Ed_unity , I just did try on a brand new Unity 2022.3.14 project and still giving issue.
Any news on a correction for this ? Or is it related to some other packages in the project (OpenXR, Interaction toolkit,…)
Thanks
