Or when people start claiming that theres no reason at all to compromise with anything,
everyone should just fork out thusands of $ every few years, to keep a PC up to date, if not you shouldnt be playing games anyways.

Haven't heard that one yet. If anything you need to upgrade PCs less frequent than consoles. I guess that's what choice is all about.

Thread is hilarious!

Anyways, it's funny they mention 1800p, because I generally go between 4K and 1800p (set up as a custom resolution in the Nvidia control panel), depending on the graphical demand of a game. I haven't really come across a game in 1800p that doesn't manage to hit 60fps 95% of the time, and from the distance I game, I can't really tell other than noticing an ever so slight softening of edges. It's my compromise that doesn't really feel like a compromise, like 1440p does.

DLSS 2.0 is not checkerboard rendering...It's an AI taking higher quality image like a 16k image and actually creating a lower resolution image like a 4k image. Or it will take a 540p image and reconstruct it to 1080p making it a very sharp 1080p image. 

Nvidia has a dedicated video explaining what DLSS actually is: https://www.youtube.com/watch?v=0X1RtXCvPFQ

Yes, this is nvidia tech so it's not available on any non NVIDIA cards, the only console that may use it in the future is the switch 2. Nvidia uses DLSS 2.0 on their Nvidia Shield pro tv which mind you the shield is practically a nintendo switch. It's a nifty piece of technology that will free up a lot of resources. Checker boarding is no where near what DLSS 2.0 can do. 

That's pretty much where I'm at, and likely will be for a few years more. 1440p 144hz is just too good of a sweet spot for me to pass up. I'll probably go for 4k, when 4k OLED monitors are cheap and do 144hz. 

'Why Native 4K is Useless', the hit follow-up to, 'Why Low Framerate is More Cinematic'.

Native 4k > Checkerboard.

This video clearly shows this. Sure its a decent solution if a device doesnt have the resources however its still a backward step.

Its a technique thats less demanding than running 1500p is, that beats base resolutions of upto 1800p.
Thats not a "backwards step" thats a technology that allows a console to punch above its weight.

Also sure 4k is the best.... but what if in this game, its too demanding to be realistic?
The PC with a 2080 ti struggles to keep above 60 fps in this game, at 4k.

4K native is obviously ideal. Just because some brands plan to hit that target more then others gives no reason to downplay it.

Where do you come to the conclusion that 4K checkerboard is less demanding than running 1500p?

It is only less demanding than running 1800p.
