Upcoming Video Memory Utilisation Improvements

A few paragraphs ago, we described our VRAM usage under this system as conservative. That means that our current implementation doesn't aggressively use all of your VRAM, and this causes players to get frustrated by assets being unnecessarily unloaded too early (for example, when you notice some items looking blurry for a short time).

Our engine team has been working on a better implementation that aggressively uses as much VRAM as it can to store as many assets as will fit. This is a good thing because users with mid-range or better graphics cards will experience assets being unloaded far less often than they currently do. It depends on how much VRAM you have, of course, but the issues that are currently attributed to resource unloading/texture streaming will be largely eliminated for many users. And of course, all of the above changes mean that users with low-end graphics cards don't experience crashes or frame rate drops when they run out of VRAM.

This was very interesting read.
Keeping in mind the current situation with accessibility to graphic cards can we get even more details?
I was planning to upgrade my old gtx 970 but currently it's not possible as better cards prices are insane.
So hearing that it will use better the memory available for GPU, my question s:
- will these changes improve performance for older generations like mine?
- how much VRAM is minimum, recommended, preffered?
- will for example 4GB be enough to run ultimatums without fps drops?
- any other suggestions for players stuck with old gpus?

PS. It would be soooooooo good to get some kind of benchmarks for different graphic cards with before/after.
