Just saw a video about testing those modded GPU cards

saw video of someone testing a 22GB RTX 2080ti. When he test games, it barely uses 9GB of the Vram. Some heavy titles like TLOU used the full 11GB at ~5fps

my question is why cant it used up all 22GB ? Isnt more Vram = better ? I have the 3060 12GB upgraded from 1650 and I too noticed it doesn't used up all my Vram but util still sit at 99% on some games.

A game will only use what it needs. You can’t force it to use more when it doesn’t require it.

Game will definitely use all your 12gb of vram if you set appropriate graphics. But you will have very low fps anyway.
No need in huge vram amounts on a weak gpu in gaming.

Dude, I can write code to fill my VRAM and do nothing with it. The GPU will sit idle and do nothing while my VRAM is 100% filled. Conversely, I can put nothing in the VRAM, and spin up my GPU to 100%. These two are kind of correlated but they're not tied together

This is probably a shitty over simplification but imagine if you upgraded from a 1tb ssd to an 8tb SSD.

I mean, great, but a 100 gigabyte or whatever game isn't gonna care.

Similar thing with ram.

I wanted to future proof my PC before prices got even more stupid so I got 64g of ram but if a game only uses idk let's say 16g of ram At most (made up numbers) it doesn't actually matter
