No one is saying games don't need bigger GPUs is this post some sort of bait?

Also Nvidia would probably go more into custom accelerators (tensor cores) as whole industry is moving more towards bigger VRAM and more tf32/bf16 units for AI training over standard fp32 gaming workflow and that's isn't focus of RTX class gaming cards.

And 4090/3090/2080ti is old Titan class card for prosumers mostly focused on 3d rendering/video editing etc. and also gaming for AI pros they are milking sweet money out of quadro lineup.

If you are rly limited by VRAM you should just go fully TPU not wait for some magic consumer VRAM increase as it won't happen for a few years probably (most games in 4k can't utilise 16gb.)
