running animation performance drops at 1st time, but later it becomes normal

[tywang2006]

Hi guys, i  run renderer.textureManager.updateTexture(resource.texture) every time when the texture loaded before the game starts. I assume it will be successful to upload texture to GPU. However, the animation make the game frame drop slightly obviously at the first time then it back to 60fps at normal. Any one has some idea about it, the animation texture is very big because the game needs to run in full hd resolution. thanks

Do you use filters on it?

no filter:(, it is only happening with hd quality animation. PIXI is 4.4.3

[ivan.popelyshev]

Masks? I'm just searching what can possibly allocate temporary texture at the first frame.

[tywang2006]

i did have a mask

OK, then you have to render any element in HD before we you the game. Just empty container with "filterArea = app.screen" or renderer.screen, and "filters = voidFilter" will do. voidFilter should be "new PIXI.filters.VoidFilter()"

I found a issue, when i call renderer.textureManager.updateTexture(resource.texture), it return null, but check source code, it should returen gltexture instead.

 

then I have another queston, why it will return null, it means the texture has been uploaded to GPU, which doesnt make sense to me

        if (!texture.hasLoaded)
        {
            return null;
        }

You sure that loader has finished its job at that moment?

OH, you yhave to pass BaseTexture there! "updateTexture(resource.texture.baseTexture)"

Ivan, i found another issue, during the time playing the game, some animation will slow again like What i said, is it due to gc rule internally, if some animation not fired for a while, it will gc automatically? that is what i guess, i think you are far more understanding its GC rule:)

[ivan.popelyshev]

yeah, "not fired for a while" , exactly. You an turn it off

"renderer.textureGC.mode=PIXI.GC_MODES.MANUAL" or something like that

cool, so this gc mode is only for  webgl to manage gltexture, is that right?

I did PIXI.settings.GC_MODE = PIXI.GC_MODES.MANUAL; but it seems not working, the gltexture seems been gc while it hasnt been used for a while

[ivan.popelyshev]

because you create renderer/application before you change the setting?

haha i read source code, i did 

PIXI.settings.GC_MODE = PIXI.GC_MODES.MANUAL;
          app = new PIXI.Application(width, height);

so renderer is created after setting gc haha

[ivan.popelyshev]

Are you sure that "renderer.textureGC.mode" is 1?

basically the render.textureGC.mode is not avaliable, it is all from PIXI.Setting.GC_MODE. it seems fine now, if the issue is raised again, I will check then discuss with you:d0
