#yes, it doesn't happen on build.. or if
buoyant sorrel
i do believe it is the same spike
took me a minute to figure out the keypresses i needed to do to capture it.
Its taking me a minute to figure out how to debug this..
someone just suggested I do a deep profile + call stacks
but when I use deep profiler the frame rate is low enough as to not have the visible frame drop like im seeing here
at other times its my player loop
it appears that my code is .5% of the spike i keep seeing
or ~2%
twilit thicket
at other times its my *player loop*
Seems to be coming from the render loop
Why don't you expand it?
The numbers don't match though
buoyant sorrel
Why don't you expand it?

i did here i think
its the EditorBeforeUpdate.invoke

In the graph you have like 100ms., but the hierarchy shows only 2-3ms
buoyant sorrel
NomNom just had me test a blank scene..
a completely empty scene also has the big ole spike
completely empty scene causing 149ms spike
has to be some asset i have
twilit thicket
I do t see the CPU timings
But if it's the editor loop, you'll need to profile in editor mode
twilit thicket
I mean in the hierarchy
buoyant sorrel
But if it's the editor loop, you'll need to profile in editor mode
ya, im trying to figure that one out.. this is the first time ive ever actually needed to profile like this
buoyant sorrel
I mean in the hierarchy
ohh yea
twilit thicket
I don't really care about the graph. All the info you might need is in the hierarchy view
buoyant sorrel
profiling in edit mode is tricky to me
i'll figure it out after i play with it some more.. im trying to figure out the order of how i need to get it running
twilit thicket
You can toggle the record button to stop it from scrolling
buoyant sorrel
ohh lmao..
this is what was visible earlier.. but imma have to try again.. i got to reset my scene right quick..
i was asked if im stacking camera's as well.. which i am not
twilit thicket
That was a wrong frame. Only 3ms
twilit thicket
Hmmm... Kinds looks like something that would only be called once during app load.
Or scene load I guess
Per camera
Unless you're rendering to a render texture
twilit thicket
Have where? Is it referenced by a camera in a scene?
buoyant sorrel
wow.. its actually being used as a base map on a material
its in my project window.. (not in scene)
i think ur on to something
twilit thicket
Hmm... I don't think that's related. Since it's the editor loop, it's likely related to rendering the scene view.
buoyant sorrel
ya, ur right.. false hope lol
soo.. it is scene related..
especially since the build has no spikes
twilit thicket
Can you take a screenshot of your whole editor window when that happens?
twilit thicket
it actually happens *without* the game even running
That would make sense, since it's the scene view rendering. If it wasn't running you wouldn't see anything in the scene view.
buoyant sorrel
does any of this info help?
twilit thicket
So you're saying that the same spike repeats periodically?
buoyant sorrel
yes like every couple of seconds or so
i use the blue timer to help me identify it
if my frame rate is lower. then the spike takes longer for it to become apparent.. which is also odd..
if i get the framerate down to 20-30 fps i dont even notice one
i noticed that when i was deep profiling
twilit thicket
Can you capture the info of a second spike like that? I assumed that the screenshot is from the first spike you encountered?
buoyant sorrel
yea ill try
twilit thicket
if i get the framerate down to 20-30 fps i dont even notice one
The spike is more than 100 Ms though, so it should be noticable even on 20 fps.
buoyant sorrel
i waited for the 3rd spike.. on an empty scene theres more spacing between them.
heres a version w/ the scene i was originally using
twilit thicket
It seems to be running a camera setup.
I've no clue why it would do that.
Perhaps the old camera is being destroyed for some reason?🤔
buoyant sorrel
i think im going to have to put this down for a minute. its taking longer than i anticipated and I have to cook diner..
But I appreciate you taking a look at it.. I know a lot more now (or atleast what to look for)
i'm going to pick back up on it when I can.. and now there's a thread so If i find out the issue or get any more details.. i'd be happy to share
im going to try to isolate just my stuff a bit more.. get rid of some third party assets i have in the project folder
twilit thicket
Actually the setup seems to be done on every frame. Can you check the same hierarchy on a frame without a spike?
twilit thicket
Can you expand the setup here?
buoyant sorrel
twilit thicket
Hmm, so it creates a render target here too.
Can you expand it the same way on a spike?
twilit thicket
Aah, the render target setup is not what was heavy!
buoyant sorrel
yea, sorry the way the Repaint parts are split in half had me confused
twilit thicket
Seems to be bloom post processing effect. It shouldn't be that slow regardless.
Can you disable bloom and confirm that the issue is gone?
Wait, does it mean that you had pp enabled in an empty scene too?
buoyant sorrel
no im back in my original scene..
but the other scene didn't have a volume
ur right.. ill try anyway
twilit thicket
In this case, either there are 2 separate problems, or the bloom hides the real issue.
buoyant sorrel
yea theres still a 151 ms spike w/o any PPFX
twilit thicket
Can you hide the game tab so that it doesn't render and see if the issue occurs?
twilit thicket
Yeah, but is it the same? Expand the hierarchy.
buoyant sorrel
no, i think its different now.. the time drops off before we get that far down the hiearchy now
ya the numbers are a little less now
ah, nvm i think they're pretty similar... the GC alloc dropped alot tho went from 40ish to 9
if anything, atleast im familiarizing myself with this profiler.
twilit thicket
That's weird the OnGUI itself is taking all that time. There must be something hiding from the profiler.
buoyant sorrel
ya, i agree ( i mean.. i dont know as much as u do about this stuff ).. but since the very beginning when i noticed this problem.. it seemed to not make any sense
and i wish i would have noticed it sooner.. theres no telling how long ago this has been happening.. and i never noticed it until i added a camera script
twilit thicket
Just to make sure, when you tested a new scene, was it in an empty project?
buoyant sorrel
no, it was the same project, just a blank scene w/ camera and light
twilit thicket
Okay, does that happen in an empty project then?
buoyant sorrel
no.. (i made a new empty scene earlier)
where as this scene my low fps is 0 - 10 fps
but that video i just sent was not URP.. b/c i thought maybe my version of Unity's URP has a bug
i can try a blank URP project using this exact version and report back..
but it'll take me a min
