Yes, just two games I know of so far in Godfall and Far Cry 6 that can use up to and beyond 12GB when properly tested.
Do you think video memory usage requirements will go up or down? Will there by more games going forward with 4K Texture packs or less? We shall see.
That's my use case and opinion. Others will have a different use case/opinion (which is fine) and don't mind compromising on settings to bring down usage requirements.
From looking at the Far Cry 6 thread though, it appears quite a few people would like to use the 4K Textures and are not able to as they don't meet the minimum requirements, so if that is the case then 10/12GB is not enough. If you don't play Far Cry 6, then it is enough for now. It really comes down to individual preferences.
But as I said in my original post, if you don't mind turning down a setting or two in any games that come with higher video memory requirements then yes 10-12GB is fine.
