Game freeze followed by gas render reset on timelapse screenshot

there is 3 commands what causes this

texture2D.ReadPixels(new Rect(0f, 0f, (float)renderTex.width, (float)renderTex.height), 0, 0);

byte[] bytes = texture2D.EncodeToPNG();

File.WriteAllBytes(text4, bytes);

first two comes at unity self

soo we can blame them

last one is c# self

that is  mostikley possibe add to the thread. i not know yet about those 2 unity ones

the whole WriteToPng functon may take over 200 milisec. that is enoh for see the game freeze

---

soo i made some tests

everything at inside WriteToPng  after the command

UnityEngine.Object.Destroy(texture2D);

is possible add to the thread without crashing the game

that does decrease the freeze time allot.

ok i made more tests

seems like

            byte[] bytes = texture2D.EncodeToPNG();
            UnityEngine.Object.Destroy(texture2D);

is possible add thread as well

now doing that it removes the most freeze

because only by toning that you remove over 100 miliseg freeze at main thread what is used by unity game self

 

ReadPixels not possibe add. i try that as well but it crashes

those tests are done directly inside game dll. i not see why i should make mod when its game code fault

 

i think there is also possible somehow write custom ReadPixels i read at unity forum that they originally use the glReadPixels and some other functions

soo. i minimize the WriteToPng  to very low time.  but then i i found there is another "ReadPixels"

JUST TORLLORORORLLLLLL

that sits inside "IEnumerator Render()"

that is another 200 mil-sec time loss

i not even know how to fix this "IEnumerator Render()" atm by make mod because they are freaking private command stuff

anyway as you now use the Unity 2020

you can fix those ReadPixels with command called AsyncGPUReadback.Request

this is good example how use them instead off the ReadPixels

also if scroll back in history then this command not existed at kind off very old Unity Engines soo its understandable why it still not fixed

if talk about the "AsyncGPUReadback.Request"  then it little act like Thread as it not have code pause in main thread soo you to need also change some IEnumerator Render() functions

this stuff is affected also when game does autosaves. you decrease allot freeze time both off them when you change them correctly

ah yeah . i posted that also in other thread but

also add the "File.WriteAllBytes" to inside Try catch command . i to seen before that code may crash at time when it saves file to hdd

i not even talk about only your code, but my own app back off old days todo that when i saved file to hdd
