You would a graphic card of >50GB+ of VRAM (which don't exist). That = would be a fatal, dead on arrival design flaw. I'm not sure why this would be a design flaw. This is the VRAM needed to do things in real time. Less VRAM means frames need to be shuttled in and out of VRAM, which takes longer, and you will not get real-time playback, that's all. You don't need 50GB+ to handle 50 layers. You'll just have to render before you can get smooth playback.
