Could someone please explain what the Upscaling using AMD FidelityFX CAS setting does?

I think we use CAS wrong. Saw a CAS Vid with Cyberpunk 2077 and they use a slider to lower image quality and get some more fps. Will test this now and give feedback.
 
Down To Earth Astronomy has a great video explaining this

I did what he did, but if I downgrade supersampling below 1, it's really bad. Like "hello 1998 bad" with blurry people, and pixel everywhere. Running 640*480 kind of bad. If I go below 0.65, the text in the menu is completely blurred.

Not close to what the have for the same value.

Then, when I use upscaling as he is, it's still looking the same, but with added weird "dot" effect on everything.
This is the comparison with the same value between him and me :

As you can see, despite having the same options, my screen look terribad. So, what did I miss ? I'd appreciate any help. Using 1920*1080.

Mine looks good with:
supersampling: 0.75,
upscaling: AMD FidelityFX CAS enabled,
AMD Fidelity CAS Intensity: 50%

Still super blurry, and the "lines" are all "broken", like the white and yellow lines above the direction, or the barrier on the left. I don't seems to have what he had on video.

Still the same artifacts, just less severe. And the FPS gain is minor at that point (5-10 in concourse).
I feel I missed something on the video he is using 0.65, yet it doesn't look that bad.

Thank you for your help though :)
I commend you for trying, but that's basically a placebo. This is not a proper good looking upscale. That would be indeed FSR, or DLSS 2.0 (Even 1.0 is iffy). And having to lower the internal renderer is really.. pathetic. There, I can't find a different word for it. For crying out loud, this is not exactly a high tech engine running ray-tracing, now is it.

Yes it chugs along, but turning my 80-90 I had in Horizons into 30? Yeah, no thanks.

I mean it's not placebo, but it's bad, I know.

I'm not excusing them for what we have. I'd just like to play a bit before the end of 2021 or the beginning of 2022, you know^^

You are absolutely right that we should not have to do it. :)

But as long as we don't get performance fixes we have to do with what we have.

Evochron Legacy SE is on sale right now :p And so is Everspace 2 ;)

I think I tried evochron years ago. Got a headache in the tutorial, didn't understood half of it :D

Everspace 2 is Early access, and I'm not a huge fan of playing a game before it's "complete". Maybe some day.
 
FidelityFX CAS is a sharpening filter. It is supposed to restore detail from blurring artefacts such as those produced by TAA or upscaling.

FidelityFX Super Sampler is an upscaler and a sharpening filter (in effect, it juste use CAS as sharpening filter).

Since ED include natively an upscaler, FDev just need to implement CAS to get the equivalent of Super Sampler.
