@andrewle9510 , In case you didn't find the answer in the link shared or for other people searching, such behaviour is due to vertical sync or vSync. You need to disable it in order to allow the application to run based on the performance of the machine or the frame rate set in the Application.targetFrameRate
(which is essentially a maximum).
Hi, to make it a bit more performant, since it's getting called so often, maybe you could cache that wait, something like
private WaitForSeconds countWait
assign it on Start()
countWait = new WaitForSeconds(0.1f)
and then just call
yield return countWait
Thanks for the code by the way!!
Very good stuff thanks !
Thanks for this!
I've also added to @dginovker code:
[SerializeField] private Rect location = new (5, 5, 85, 25);
[SerializeField] private int fontSize = 18;
[SerializeField] private Color32 fontColor = Color.black;
to change things on the fly (I'm working on a VR title so I have to nudge things around due to screen real estate).
*Sorry for the multiple edits
** UPDATE OnGUI doesn't work within the headset, but will display on the Game window within the editor.
To get smooth FPS (Weighted average over time):
using UnityEngine;
using System.Collections;
public class Fps : MonoBehaviour
{
private float currentFps;
private float smoothedFps;
private float smoothingFactor = 0.1f; // Adjust this to control how much weight is given to recent FPS
private IEnumerator Start()
{
GUI.depth = 2;
while (true)
{
currentFps = 1f / Time.unscaledDeltaTime;
// Apply exponential smoothing to calculate the weighted average
smoothedFps = (smoothingFactor * currentFps) + (1f - smoothingFactor) * smoothedFps;
yield return new WaitForSeconds(0.1f);
}
}
private void OnGUI()
{
// Display the smoothed FPS
GUI.Label(new Rect(5, 40, 100, 25), "FPS: " + Mathf.Round(smoothedFps));
}
}
