16GB should be the industries aim for midrange GPUs. 12GB for budget GPUs. You can make a 12GB card work in the midrange space, but AMD, Nvidia, Intel, they must know that many gamers will not buy it because of its limited VRAM buffer. I'd happily take a 12GB card myself because my personal circumstances doesn't require more, but RT, high textures, high resolutions are a popular feature now and should be available in the midrange market. These are things gamers are actually interested in now. Nvidia pushed RT hard when it wasn't ready. Now that it's here and shaping up well, Nvidia don't want to sell you the cards that support it properly because of VRAM when their RT cores are capable.
