performance strange issue

Hi.

I'm stuck with a question. When running my scene in editor play mode, the stats say i got 120ish
fps....
it appears the stats are lying
when i physically measure the frame rate i'm about at the half stats say !!!
and disabling VSYNC is useless.....
here's my simple code for fps measurement:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using System.Collections;
4.  
5. public class FPSCounter : MonoBehaviour {
6.  
7.  
8.  
9. public float updateInterval = 1.0f;
10. public Text GUIText;
11.  
12. float accum = 0.0f; // FPS accumulated over the interval
13. int frames = 0; // Frames drawn over the interval
14. float timeleft; // Left time for current interval
15. float fps = 30.0f; // Current FPS
16. double lastSample=0.0;
17.  
18.     // Use this for initialization
19.     void Start ()
20.     {
21.         timeleft = updateInterval;
22.         lastSample = Time.realtimeSinceStartup;
23.     }
24.  
25.  
26.     void toggle_draw_fps()
27.     {
28.         if(GUIText.enabled)
29.             GUIText.enabled = false;
30.         else
31.             GUIText.enabled = true;
32.     }
33.  
34.  
35.     void Update ()
36.     {
37.         frames++;
38.         double newSample = Time.realtimeSinceStartup;
39.         float deltaTime = (float)(newSample - lastSample);
40.         lastSample = newSample;
41.  
42.         timeleft -= deltaTime;
43.         accum += deltaTime;
44.      
45.         // Interval ended - update GUI text and start new interval
46.         if( timeleft <= 0.0f )
47.         {
48.          // here we got the frames number and accum for the time they took to draw....
49.          // lets get the mean time for one frame and show how many of those frame-time we got in 1 sec
50.          fps = 1.0f/(accum/frames);
51.      
52.             // display two fractional digits (f2 format)
53.             GUIText.text = fps.ToString("f2")+"fps";
54.             timeleft = updateInterval;
55.             accum = 0.0f;
56.             frames = 0;
57.         }
58.     }
59. }
60.  

here is a screenshot:


What's wrong with fps ? i can't believe this could be a bug ?????

 

The editor FPS statistic is just a curiosity value, nothing more. It is affected by a great number of things. You should use a build for real framerate values. Better still, get used to using millisecs.

Unity editor is not the place to test this. It's doing a million additional things all the time, and thus has no real value beyond curiosity and doesn't reflect your game's performance.

Think about it for a moment. Look at it. It's not just your game is it?

 

ahahah sure hippocoder unity editor is MY favorite game !!!!

okay i thank you a lot for this answer as i really was surprised for the difference between my measurements
and stats info. I've been tricked by the former ( long ago was on unity 3.4 ) measurements i made that were
almost identical to what stats said.

have a nice day
