What on earth are you smoking? My 1080ti handles 1440p, even on Ultra settings, just fine. I think the only game that makes it cry is Cyberpunk 2077, but that game brings most GPUs to their knees if you push the settings.
The simple fact is that the XBSX and PS5 have 16GB of VRAM. Games that are built to run on those consoles are designed with that much VRAM in mind. Whether you have enough VRAM is a fairly binary data point - you either have enough or you don't - because you can't really compress the game textures while they are in use. At this point, 16GB should be considered the minimum a mid-tier GPU should be shipping with, but nVidia is still trying to get away with 8-12GB cards.
Dude, your 1080 Ti don't handle new demanding games on ultra settings in 1440p LMAO. Lets be real now. Only if your fps goal is low, meaning console level low. Older and lesser demanding games, might run fine with playable fps on high setings yeah, not demanding ones. My guess is that you don't play new and demanding games.
I replaced my 1080 Ti years ago, because it was too slow for 1440p. I demand 100+ fps at times, on high settings - not ultra - I always tweak settings manually. Ultra preset often forces crap like motion blur and DoF... Useless.
Cyberpunk 2077 is not demanding without RT. What you you smoking? If you think it is, it just shows the age of your 1080 Ti. My 3080 maxes it out easily without RT and DLSS Quality mode works wonders in this game, allowing for 125-150 fps using very high settings. Without DLSS Quality, I still run close to 100 fps.
2080S replaced my 1080 Ti (pretty much a free upgrade, because I was offered alot for my 1080 Ti and got the 2080S for cheap) ... and 3080 replaced that one, for 699 dollars on launch day. Huge upgrades both times. Tons of games will make your 1080 Ti bleed, try RDR2 on max settings in 1440p, you will be looking at 25-30 minimum fps, and ~40-45 avg. This is a 5 year old game.
Just because you avoid demanding games, or lower settings, don't mean 1080 Ti is still a high-end GPU. It's not even mid-end today, more like low-end. Cards like 3060 Ti completely smashes it + has option for DLSS on top.
GTX is outdated and the 1000 series gets zero optimization in never games either. Not from game devs and not from Nvidia. It's a 2016 arch, 7+ years old at this point. Obsolete tech. Nvidia has full focus on RTX series. GTX is pretty much dead at this point, no focus at all. Just because Nvidia supports older cards in their drivers, does not mean they are doing anything to improve performance or fix errors in games. This is true for AMD as well. When a GPU is 3+ generations old, forget about optimization. The card might die any day as well. It's pretty much trash.
The fact that you think PS5 and XSX have 16GB VRAM shows me you have no clue. They barely use 6GB for actual graphics. Games are not built for AMD just because consoles use AMD. Lmao. We are using standards here. X86/X64 and DX/OGL/Vulkan APIs.
