Lol! 1080p recommended at ultra settings is 8GB+
The scary thing is that I've seen that happen, or close to it, with ROTTR/SOTTR when AA is cranked to max. Ironically though most people would never do that because it tanks the FPS unless you have a really powerful GPU solution.
I've seen the Resident Evil games consumer VRAM though. Push 'em up to around 1.3 quality level, most things maxed, and 11-13 GB easy in 4K but again you need a really powerful card to keep it around 60+ FPS then.
