That just shows so many people are worried that 10GB will not be enough
For the most part I imagine it will be enough, bound to be some outliers that edge it. The main problem with games is they cache a lot of vram but might not be using it, I don't think there's currently any real way to monitor via third party app just how much vram is being used for textures etc vs cache. Some games just suck up all the vram they can because its available.
