When loaded images begin to use GPU?

[canvasman]

When I load image with PIXI.loader or with PIXI.Texture.fromImage(), does it reserve memory from GPU before adding the texture to actual sprites and them to stage?

At first render pass. If you want to upload them before render, look here: http://pixijs.download/dev/docs/PIXI.prepare.html

Or use good old "renderer.textureManager.updateTexture(myTexture)"

No. We don't upload the texture until the texture has been completely downloaded and we need to render a sprite that uses it (so it is in the stage). The first time we encounter a new texture on a render pass is when it will get uploaded, there is no preallocation that happens.

You can upload it manually if you need to like Ivan mentioned.
