Hi, what is really this parameter?
I changed from 100 to 80 and i really dont see any change but the frames goes up

Resolution basically.
Lower render = more frames lower visuals
Higher render = less frames better visuals
100 will be equal to your screen resolution at the top of the graphics settings page. Lower will reduce the screen resolution, more will overscale and isn’t recommended.

I run at 120% render scaling because it greatly reduces the popping and crawling effect of distant and narrow objects like rivers, and my 1070 card seems to be able to handle it perfectly fine. At 200% I can even turn off anti-aliasing but the frame rate is awful. I wish the render scaling would automatically adjust down when the frame rate slows below a configurable minimum, and back up again when there’s headroom.
Just to add a little more info:
Render scaling sets a specific resolution for the GPU which is lower, equal to or higher than the screen resolution. The GPU renders the images in that resolution and then scales it down (or up) to fit the actual resolution of your screen (or the actual set resolution in the game options).
The technology is also known as “Super Sampling”.
Why this is done I hear you asking? Well, this way you can achieve one of two things:
- improve overall graphics performance by reducing the render resolution so the GPU has less computational effort to make -> Do this when your system resources are limited and you want to gain FPS by sacrificing some overall quality.
Note: Nvidia has achieved very good results with their DLSS technology which allows faster rendering without giving away too much visual quality.
- improve overall graphics quality by increasing the render resolution -> Do this if you got spare system resources (especially on the GPU side) and want to gain image quality by sacrificing some fps.
Note: A nice side effect of downscaling the image after rendering is that you are likely to be able to refrain from Anti Aliasing to some extent or at least lower the AA settings because the downscaling process basically does the same (without going into detail).
Another thing worth mentioning might be that the amount of improvement (or loss) of image quality might depend on the actual scaling factor. Not in a sense that “higer (or lower) is better” but in the actual factor: 125% might even give better quality than 130% as it’s mathematically divisible without remainder so the GPU has less pixels to interpolate for the final image.
That may depend on the actual algorithm (not sure how deep learing handles that problem) and is probably too much detail already.
Edit: typo
