how to draw textures faster?

[zeeb137]

I need to draw textures pixel by pixel faster.

I can make colors buffer and use it to create texture, but that's not fast enough for me!

I can use fragmentshaders but they update every frame is there any other way to do it that takes advantage of OpenGL performance without updating everyframe?!

Nothing can stop you!

I dont see a problem. Give me an example.

I'm getting confused.

The problem is that shaders draw every frame taking extra resources instead of drawing once!  i'm correct right ?

then.. draw it once to renderTexture and use renderTexture in a sprite later? That works for heavy shaders & filters, but if you want pixi automatically determine whether something was changed - nope, not happenning, i have the fork that does it but its just not possible to open-source, the code is completely bonkers.

Oh, so it was about "Texture.from(canvas)" and "texture.update()" , right?
