Render Scaling vs Resolution

[The Torrent]

Render Scaling vs Resolution.

Following is said in case of Rainbow 6 Siege.

 

Under display comes a option to change the display resolution. In my case i have always had it at 1600 x 900.

 

Under graphics comes a option where you can change the actual render scaling via temporal upscaling 

 

All this is standard.

 

By auto, my resolution was set low (1600 x 900) and render scalling set high (80)

 

Why is this though. These are the settings chosen by Nvidia Experience.

 

It seems to me would it not be better to have the resolution at your native (in my case 1440p) and the render scaling lowered?

 

Please explain pro's and cons of each.

 

I have said what everything is in my terms in this post but would like things to remain general for others.

 

Many Thanks,

TT

Do you mean 80% or 180%?

Basically your selected resolution = render scale at 100%

 

If render scale is 80% then the game renders at 20% lower resolution than what you set it to

I believe scaled rendering is mostly to allow you to use a final output resolution of your choosing while not requiring the game to actually render at it. For example, if you want to use borderless windowed, most games require that the resolution be the same as the desktop. This is a problem for 4K displays because 4K on desktop looks really nice, but it's a slog to run. So if you can render the game at a lower resolution, it'll help.

 

It's also somewhat helpful for full screen exclusive modes because if you run the game at a lower resolution than the desktop, the desktop window configuration may shift as if it was at the resolution of the game.

None of you understood my question, the last guy the closest.

 

I'm asking pros and cons of having high render but low resolution, vs high resolution and low render. (but scaled with temporal upscaling)

You cant go above 100%

 

And in the case you was trying to mock me by saying 80% is not a lot, i'm not running dual 2080ti's rainbow 6 ultra 120fps 1600 x 900 is all i get. (180fps uncapped).
