The 50% of the time the game thread is waiting for some task
And there is not more info in the timers panel
How i know what task is it waiting for?
Thank you so much
From the drop down it would indicate that it’s waiting for a tick function to complete.
You can usually find the blocking task by looking at the other functions that are happening on the graph that lineup with the waiting for bar, the operation could be happening on another thread somewhere below.

Ok, Thank you so much @3dRaven
It is difficult to say for sure without seeing all trace tracks in that frame, but looking at the screenshot I think it is waiting on Rendering.
I see Render Frame waited 8.6 ms (possible due to the PSO precache shown in the track bellow). And then spend the rest of the time doing rendering work.
The game thread track seems to wait until this rendering work is complete, as both the render and game thread track finish at the same time.
The advice @3dRaven gave is correct, you usually try to see how the tracks line up to see what work is being done.

Thank you very much for your reply.
Should I assume there is too much stuff being drawn on the screen?
I was looking at the threads below.
I found this on the HRI thread:
And I also found this in the rendering thread:
If that is responsible for the drop in performance.
It seems like it’s the sum of a lot of things.
Can you give me any advice to improve this?
Thank you so much!!
Seems the audio is processing after streaming taking up some resources. Maybe choosing other compression methods or audio formats could help speed this up?
Audio again, workers doing audio stream building
At the end of the graph there is a large spike of activity regarding what looks like a recursive package search
What looks like random in-game shader compilation. Maybe do a pre pass of shader compilations (show the shaders one by one in array on a polygon to have the engine pre-compile them before gameplay instead of when a effect suddenly needs a shader)
this might also fix some random stutters that occur with PSOPrecacheUnkown where it builds the graphics pipeline state mid game
or look into this to maybe teak the precaching in some way:
Not that much really stands out. No jarring errors. There is some calls to updating primitive scene info, maybe check if all of the unmovable parts of your level are set to stationary or static.
Character movement comp takes a bit of a hit, maybe mover 2.0 could be an option in the future.
Run the scene and do an F5 pass to check your shader complexity and try to get everything to green if you can, there are some deferred shading scene render nodes that might be able to be optimized.

Hi @3dRaven
All the audio files I’m using are in .WAV format. They are usually very small. Less than 100 Kb
The sounds usually last half a second or less.
Do you recommend that I use another specific type of format?
I think that’s because of the map changed (Return to the main munu).
When I leave the game this happens.
This is the trace after compiling shaders. I see everything more or less the same as before.
I take a look at it.
All moving actor meshes are set to Movable:
SceneComponent->SetMobility( EComponentMobility::Type::Movable );
What is move 2.0?
Neither F5 nor Alt+F8 works… the keyboard shortcuts must be broken.
However, I see everything green except for some particle systems that are red.
Weapons have some translucent and emissive materials as well.
The only thing that is not there are the particle systems that are spawned when the game starts and the pawns. This occurs at the beginning of the trace. After this they are disabled until they are needed.
Thanks for the help @3dRaven

I’ll take a look at it. Thank you very much.

I’ll take a look at it too. Thank you so much
You can also use aa dithering to fake transparency if the effect doesn’t need to be precise.
Shader complexity view shortcut seems to be moved from f5 to “alt + 8”, default lit view is “alt + 4”

Cool, I’m going to experiment with that.
I always seem to come up with the most expensive stuff.
Weapons have transparent, colored and emssive materials… All in one… The perfect combo for a big performance drop… but it looks cool. XD
Let’s see if I can achieve the same effect using that trick.
Thank you so much @3dRaven
For some reason on my computer the Shader complexity of the material looks orange.
Am I using the same configuration as you? (Surface, Masked and Defauld lit)?
Orange is definitely better than red… but it’s weird…
Does it have anything to do with different graphics cards? (GTX 1080Ti)
Maybe its the lighting mode advanced settings. I’ll check later on and let you know.
I’m on a 1060 so lower tier.

Ok, thank you @3dRaven
With this material you can achieve a very retro effect. All pixelated.
It brings back memories from when I was a child. XD

It worked
"Float Precision Mode" and "Decal Response (DBuffer)"
Fixed the problem. Now it’s all green!!
Now I can apply this to other materials too!!
If it improves performance without decreasing quality then it’s good!! 
Thanks you so much @3dRaven 
The trick is amazing.
I wish I had known this before doing all my effects.
Now I’m going to have to fix a lot of things.
This makes me think of all the super cool effects tutorials on YouTube.
You spend four hours doing an effect that looks great… but then it’s useless because the performance is garbage.
So I almost wonder if there is any point in being a VFX artist.
Most of their work is useless in games…
Well maybe for movies or something like that…
Thank you so much @3dRaven
