Oh dear, I see we have yet another secret sauce in making. /facepalm
It's not "secret sauce", you can understand the basic concept of lower resolution being easier to process yes?
Like you understand rendering at 4K will tax as system more than rendering at say 720p? Right?
There is no dispute about that.
DLSS 2.0 simply lets you render at 720p and get an 1800p or even 4K image, and this is not theoretical, it's possible right now in actual games and you can see the difference. The PC game CONTROL already allows this you can have your PC render the game at a laughably low 576p resolution and it creates an image very close to native 1440p.
There's a video that shows CONTROL running at 512x288 resolution ... this is basically the same pixel count as Perfect Dark on the N64 from 20 years ago ... and honestly for an undocked mode if you had to really go that low, it looks reasonably playable even at a laughable resolution like that.
You can see it right here at 10:26 into the video, 540p versus 1080p ... 540p is 1/4th the resolution of 1080p, it's almost Wii/GameCube resolution versus 1080p which the PS4 sometimes struggles to hit. The hilarious thing here is the 540p image with DLSS actually looks sharper and better to me than the the real 1080p, lol.
Lets face it, Nvidia is just far beyond AMD, AMD is just now releasing GPUs that can ray trace this fall ... Nvidia had equivalents to that 2 years ago with their RTX Turing GPUs. Maybe in 2 years AMD will have something like DLSS 2.0.Last edited by Soundwave - on 23 May 2020
