It is not even near to what TeXLive (TeX distribution) provides

It should also be pointed out that at 32767x32767 pixels (or 2^15 in each direction) you need 1GB per byte you want to store for each pixel. Or in other words at the usual 32bit per pixel you would need 4GB just to store the screen and another 4GB for double buffering.

Even at 8k screen resolutions ( UHD, 7680 × 4320) you are already at roughly 128MB per image.

Now keep in mind that this is just the screen, to make this useful for e.g. 3D you would have to load dozens, hundreds or even thousands of textures of a comparable resolution for a given 3D scene.

Modern RAM and VRAM amounts just can't supply that kind of data fast enough, especially when you want the ridiculous 144Hz some gamers would like at the same time.
