Sorry guys, it seems like a battle between peasants in the mediaeval time... no offence
Developing for MSFS 2020 (known abuser of GPU) I can tell you that moving forward 10gb will be saturated pretty quickly, yes the engine can get data as quick as you want, but if I model something and want to texture it with some very high quality material and very high resolution maps, sorry but I need your GPU Vram, if it displayed on the screen it has to be in the GPU not on a super duper SSD. Else you will have to lower your settings and not get the experience I wanted you to have, this hold back the platform really.
Now how long that will be is another story, the fact that Nvidia knowingly release a card with 10gb VRAM to double dip their known fanbase isn't exactly a secret, they did so with 20xx and the same people screaming "Heresy" are the same one that bought 2080ti and got absolutely no RTX games for it but a couple, worst the other ones got "Super" card with specs that should have been on the launch's card.
I tend to use Nvidia and did so for the past 10 years (before that I cannot remember rally) but when Nvidia fanboys call "Lisa best fan" whilst at the same time showing poor judgement, lack of common sense, adoration for a brand that is screwing not just the GPU but overall PC Gaming is frankly, as said, a fight among peasants, or like we say where I am from "THE OS CALLS THE BULL HORNS ONE" as bad as each other.
10Gb won't be enough for 4k as much as people like to cry, Nvidia pulled another 20xx there, also as probably the only youtubers one can trust are pointing out pricing was never £6xx for a 3080 and AIB are all complaining about Nvidia being greedy forcing them to increase prices further.
When people defend anti consumer companies I feel pity, AMD isn't any better as they are following AMD as we all seen with ridiculous pricing, despite being strong anyone working with markets and customers in other industry knows that if you try to win over a client used to custom with another brand, you have to win on pricing first and foremost, not value for money as they (wrongly or not) see value on their current provider. Of course they see people being easily fooled and try too.
3070 is the most glaringly obvious example, £500 for a card that will have to lower res of texture to play games than a £500 consoles, and anyone with a bit of gaming development knowledge would know that with Teraflop only you can wipe where...you know where.
