Is there a max libGDX texture size for desktop?

Question

I know that on mobile devices, the largest texture you could render in a single draw differs: sometimes it is a mere 1024x1024 - other times 2048x2048 etc.

What is t

Answer 1

In addition to what P.T. said, I wanted to supply the code for that (in libGDX).

IntBuffer intBuffer = BufferUtils.newIntBuffer(16);
Gdx.gl20.glGetIntegerv(GL20.GL_MAX_TEXTURE_SIZE, intBuffer);
System.out.println(intBuffer.get());

On my desktop system this results in 4096, meaning that the max size supported is 4096x4096. My system is not that old though. You should probably not assume that 5000x5000 is available on all desktop systems. Usually you don't need textures that big so not all GPUs support that. You can always split it up in several textures and draw it on multiple quads next to each other to work around that problem.
