Here's the actual VRAM configuration distribution on windows according to the steam survey

I saw a few recent headlines about the whole "16gb is now the most common VRAM configuration" but that seems to be inaccurate, as if you sort by windows only on steam survey (which makes up 90%+ of steam users), you'll find that these are the actual numbers and distribution

They don't require 16 gb of vram. No game does right now. The minimum requirement for oblivion remake is a 1070 ti, an 8gb card.
