profiler has no use until u open the detail
u need to see the detail of how it was broken down
spiral kindle
Okay, he is asking what method calls
alpine sage
Change from timeline to hierarchy
thin panther
spiral kindle
alpine sage
Alt click an arrow to expand all
spiral kindle
rich mango
expand the player loop and then also every thing with over like 20% at least or like Osmal said
spiral kindle
which arrow do we expand
thin panther
apparently theres a function called "waitforlastpresentation"
spiral kindle
were thinking its the garbage collector thing
thin panther
and GC
alpine sage
GC.Collect is because something is generating garbage a lot
thin panther
can we backtrace what is generating garbage?
spiral kindle
could that be are issue
alpine sage
can we backtrace what is generating garbage?
Yeah I think you need to click Call Stacks and allow GC call stacks or something, and possibly enable deep profiling
spiral kindle
and those are from that one spike
thin panther
alpine sage
Look at other frames too
spiral kindle
thin panther
we can ignore those 0.0 , 0.5%
thin panther
focus on those 20%+ first
spiral kindle
We are going back into game
spiral kindle
focus on those 20%+ first
Can you clarify
thin panther
- first of all, enable callstack and deep profiling
- when u look at hierachy display all the callings, they will display resource usages
which is total
thin panther
1. first of all, enable callstack and deep profiling
if u enabled callstacks and deep profiling, try to run the game and test it, record the leaf data or something that will cause the lagging
spiral kindle
focus on those 20%+ first
thin panther
if GC is occupying 30% again, it would be GC problem, and because u enabled callstacks
ok
spiral kindle
He is saying its just a lot of rendering
thin panther
it was GC problem
spiral kindle
What do we do
I'm just trying to be the intermediate third party relaying informatino
thin panther
if fps dropped, it mostly because of CPU / GPU and RAM
alpine sage
Why isnt the dev asking it here instead
spiral kindle
We were showing a single spike
thin panther
can u tell him to get here
spiral kindle
Okay he'll join shortly

Hello
alpine sage
If your GC seems to be the problem in most of the frames, you need to look for what is causing GC.Alloc
You can sort by it

I sent a screen shot of a GC spike, that happened once
thin panther
u need to look for another spikes, there should be more than 1 spike
spiral kindle
a spike of what specifically
thin panther
GC spike
spiral kindle

spiral kindle
Could it be editor loop?
copper spoke
thin panther
check these spikes
alpine sage
The profiler itself can cause lag too so dont pay too much attention to editorloop
thin panther
editor loop is the recording of editor itself
copper spoke
thin panther
u dont expect player to play on the editor
copper spoke
spiral kindle
u dont expect player to play on the editor
It was me just asking the question
alpine sage
Do you know how to read a hierarchy
spiral kindle
I thought it might be, but I'm not very knowledged in Unity
copper spoke
Do you know how to read a hierarchy
yes
alpine sage
It says XRUpdate takes 54% of the resources
thin panther
XRUpdate
spiral kindle
Do you guys know at all what might be happening
thin panther
we dont know, thats why we asking u guys to profile the problem
we need to know whats happening
alpine sage
Do you guys know at all what might be happening
The profiler is literally telling you everything. Whats the issue?
spiral kindle
The profiler is literally telling you everything. Whats the issue?
We don't know the issue
alpine sage
- See what lags your game
- Optimize it
thin panther
check those bluegreen spikes, theyre from runtime, if theres heavy usage then it will be the same when u run the app
spiral kindle
We don't know what lags it, thats the thing
We think the leaves, but what about the leaves
thin panther
once u on the spike, expand all the usage on the hierachy, we need full detail on the heaviest usage
copper spoke
Dude its all this
alpine sage
We don't know what lags it, thats the thing
Thats what the profiler is for. You look at what takes the most time to process and what allocates the most memory (GC.Alloc)
copper spoke
alpine sage
I would use the Frame Debugger to see how your rendering is executed
spiral kindle
I would use the Frame Debugger to see how your rendering is executed
Were doing that rn
We'll send an ss
would going into a group gc be better for this
copper spoke
spiral kindle
were you talking about the array clear
alpine sage
Maybe take a moment to learn how the Frame debugger and Profiler works
spiral kindle
we are very confused, would you guys be fine with going into a gc
alpine sage
we are very confused, would you guys be fine with going into a gc
That sounds like work
spiral kindle
Maybe take a moment to learn how the Frame debugger and Profiler works
He constantly knows how to use he profiler and knows how to use it
We do not know or understand why it is lagging
spiral kindle
That sounds like work
And it was a suggestion, I don't know why the rude snipe/ remark
We are just confused trying to solve a problem
alpine sage
He constantly knows how to use he profiler and knows how to use it
What about the frame debugger
alpine sage
We are just confused trying to solve a problem
Youre mostly just sending screenshots
spiral kindle
What about the frame debugger
He does not about he frame de bugger
He doesn't use it, mostly the profiler from what i've been told and currently being told
We know what's causing the problem its the leaves, but we don't know what about the leaves, that's what we've been asking
We don't know what about the leaves
thin panther
no matter how u guys ask, my answer will always be:
the only way for u guys to work things out can only be inspecting on those spikes, if theres 100 spikes, inspect 30-40 of them, and find out what is constantly causing problems, if u found out it was the GC.Alloc appearing on most of the spikes, it was the GC alloc, and next step is to further inspect it
how u further inspect it? maybe frame debugger
were not the gods or ur pc, we dont know whats the problem behind, thats why were asking for the profiling
alpine sage
You can see GC alloc sources in the profiler timeline view, with deep profiling and GC call stacks
spiral kindle
We knows its the leaves as stated when we first made the inquiry, but we don't know what about the leaves
When we remove them no frame lag, when they are there frame lag
alpine sage
We knows its the leaves as stated when we first made the inquiry, but we don't k...
If youre so sure its the leaves, you should also show their material, mesh etc.
spiral kindle
Wouldn't it be the leaves
spiral kindle
Even without alpha clipping, it still frame drops
thin panther
thats not going to tell us anything, we need to see the profiler
how the leave behaves in runtime? hows the rendering going
those are in frame debugger or profiler
spiral kindle
thats not going to tell us anything, we need to see the profiler
Can we join a vc with you, its hard to explain over text and it would be much faster, we just really really want to fix the issue
thin panther
im not specialized on computer graphics, what ur encountering(if its the leaf) is something related to this aspect
what i can only tell u is frame debugger is the right way to do
because if the leaves having a problem during runtime, if it causing the lags, it should belong to rendering , and frame debugger is the key to see how the rendering goes
