What happens when the memory I create from textures exceeds the memory that the GPU has?

Well, find out:


while(true)
{
   device->CreateTexture2D(&textureDesc, NULL, &texture);
}

Better take cover first.

I think it only allocates memory on the GPU. There is no reason to mirror data in CPU RAM as well. Also, you are more likely to have more RAM than GPU memory.
