    Quick benchmark to check out regressions and such.
    With a fps script that uses ongui, frequency 30 seconds, 2060rtx i5 8400
    Scene uses no realtime lights or lightprobes, 1 refprobe, all baked & realtime volume lit by The Bakery, 20 vfx graph, 580K tris, 100 skinmesh, rufat's post processing bloom

    editor fullscreen 1280x720:
    2020.1.17 105fps
    2021.1.1 80fps
    regression of 25%

    build fullscreen 1440p:

    2020.1.17 328fps -> 310fps (drops slowly to 310)
    2021.1.1 296fps -> 310fps (ramps up slowly to stabilize at 310fps)

    Can you share the FPS script?

    1. using UnityEngine;
    2. using System.Collections;
    3.  
    4. [AddComponentMenu( "Utilities/HUDFPS")]
    5. public class FPS : MonoBehaviour

    7.     // Attach this to any object to make a frames/second indicator.
    8.     //
    9.     // It calculates frames/second over each updateInterval,
    10.     // so the display does not keep changing wildly.
    11.     //
    12.     // It is also fairly accurate at very low FPS counts (<10).
    13.     // We do this not by simply counting frames per interval, but
    14.     // by accumulating FPS for each frame. This way we end up with
    15.     // corstartRect overall FPS even if the interval renders something like
    16.     // 5.5 frames.
    17.  
    18.     public Rect startRect = new Rect( 10, 10, 75, 50 ); // The rect the window is initially displayed at.

    It's likely that the editor portion of the gameloop got slower. Could you report a bug on this?

    You've been reporting a lot of good performance regression bugs lately. I'm sure our lord and savior @Peter77 is proud up there in the sky.

    It's not really related to the RTX Unity Technologies sent me, it's more related to my interests having shifted. That's mainly the reason why I'm not so much around here lately. But I see how it looks like I was bought and it's a funny thought. :D
