FPS not getting more then 30

dharmik.6058​ Hi, How is it going?

Recommending you attach a script like below. I'm not sure if you are doing this already.
This will lock your FPS to 90. Incase if you do this already and you dont get 90, try reducing it to 72 FPS. 

You can tweak the value of

 targetFrameRate 

parameter in this code.

using UnityEngine;
#if UNITY_ANDROID && !UNITY_EDITOR
using Unity.XR.Oculus;
#endif

public class MetaQuestFrameRateSetter : MonoBehaviour
{
    [SerializeField] private int targetFrameRate = 90;

    void Start()
    {
        // Lock Unity's Application frame rate
        Application.targetFrameRate = targetFrameRate;

        // Optional: Match vsync count
        QualitySettings.vSyncCount = 0; // Disable vsync, since we are manually setting FPS

#if UNITY_ANDROID && !UNITY_EDITOR
        // Attempt to set preferred refresh rate (for Meta Quest)
        try
        {
            OVRManager.display.displayFrequency = targetFrameRate;
            Debug.Log($"[MetaQuest] Target refresh rate set to {targetFrameRate}Hz");
        }
        catch
        {
            Debug.LogWarning("[MetaQuest] Failed to set refresh rate. Ensure OVRManager is initialized and the device supports it.");
        }
#endif
    }
}

Let me know if this works. 

If you still dont get a good framerate, please share your profiler and memory profiler data with me, will try to figure the best optimization possible.
