How to check that GPU memory is released?

[canvasman]

After resetting applications state and destroy all the textures, can I see anywhere if there is still some textures left in the GPU memory or confirm that the GPU's memory has been released and there is no memory leaks?

In task manager I check dedicated GPU memory. After adding some textures and resetting application state, destroying all textures it still wont go back to where it was at the beginning.

So where and what values should I look at about GPU's memory status?

Also does every texture loaded with PIXI's loader reserve GPU memory even if its not present in scene anymore?

is this can maybe help you ?

https://chromium.googlesource.com/chromium/src/+/lkgr/docs/memory-infra/probe-gpu.md

and for awser you no this will maybe depend of your projet.
On my side somethime i need do it manualy after loader my json.

take a look with this and also pixi prepare 

$app.renderer.bindTexture(texture)

or 

$app.renderer.bindTexture(baseTexture)

Wait what is the bindTexture? I can't find any documentation.

Thanks for the answer anyway

You can manually iterate through "renderer.textureManager.managedTextures" and see whats alive, sum all by area (width * height), 4 bytes per pixel. In v5 its in "renderer.texture.managedTextures" or something like that. maybe "_managedTextures".

Okay, so in that object I can see everything which has some GPU memory reserved currently? Also textures which I get after loader is done, do they reserve the GPU all the time until they are destroyed?

Look at TextureGarbageCollector class source. I dont want to waste words on it, its self-explanatory.
