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

I feel I missed something on the video he is using 0.65, yet it doesn't look that bad.
That's because he's upsampling from near 1440p to 4K. If your screen is 1080p, x0.65 means you're upscaling from less than 720p which is too low to properly display text on the HUD.

I found that x0.75 with SMAA and CAS cranked all the way up is where things start looking somewhat acceptable on a 1080p screen. Text still isn't pretty but readable, and there's a massive fps boost which might help lift EDO above the 60 fps line for people with low end GPUs.
 
Thanks.

I have an Intel processor and Nvidia GPU, is this setting of any use to me?
It's been great for me. I have upgraded my monitor and it's now and ultra wide 1080p, 75hz monitor with an RTX 2070, 16gb ram, i5 8600k, overclocked. I'm now getting 75fps when walking around stations with drops to 60 when looking through glass. Haven't been on a planet yet. That's my next test.

I do get a little stutter when exiting hyperspace, but I got that in horizons too, so that doesn't bother me.
 
That's probably the issue.

I didn't watch DtEA's whole video, but he seems to be using a much higher resolution. There is only so much upscaling + sharpening can do and making 810p internal resolution look good is well beyond the capabilities of CAS.
I was assuming it would be part of the issue. Which is why I mentioned it. Dunno if I can go higher than that, I'll check.

Thank you for your input :)

Here's what it looks like for me. The HUD really is the critical part.

Left: "High" preset without changes.
Center: "High" preset with x0.85 sampling and CAS maxed.
Right: "High" preset with x0.75 sampling and CAS maxed.

For those struggling with low fps it's worth a shot imho.
 
i give it a go in stations i was getting 45fps with GPU at 99% or 100%
with CAS on SS at 0.75 im getting smooth experience, and GPU running at 67% with 60FPS vsync with monitor

ignore the grain thats my camera, you dont see that on screen
 
Mine looks good with:
supersampling: 0.75,
upscaling: AMD FidelityFX CAS enabled,
AMD Fidelity CAS Intensity: 50%
What I've got is x1.25 SS, with AMD FidelityFX enabled at 50%. This gives me a significant FPS advantage, but it looks great.

75fps everywhere, except for when I look through glass in stations. Haven't checked a settlement yet or the strain on the GPU.

Wait, what? x1.25 gives you higher fps than x1.0?
 
I switched CAS to native and kept sampling to 1.0 after Update 5 flickered like crazy at all times. I'm getting a reliable 60FPS (fixed) in space, and 45 FPS on planets. I have a GTX1060 and display is on either 1920x1080 or 2560x1080. I even gave it a try with surround Physx across all 4 monitors and it was fine.

I think the variance is probably more what else the PC is up to, and the base PC spec. I have a Samsung Pro Nvme, which elite is installed on, and an 8 core piledriver processor. (Toasty warm). Ages ago, I went through all the windows services that were running resident on the card and disabled a bunch of the unwanted stuff in services.
 
The guy with a 3090 has to use upscaling to get decent fps, good job Frontier,you done good.
At this rate the console launch will be worse then cyberpunk on ps4
You people who are saying "I have good fps on stations" have no idea, try driving an SRV,passing my magic rock that reduce your gpu usage to 0% and fps to 2,or fight in settlements
 
You reduce super sampling below 1 for performance and then fix the blur with CAS. For example, if I use 0.75 supersampling with full CAS, I go from 38 fps to 53 fps and still have a mostly acceptable picture instead of a blurry mess.
If this tool only serve as a visual "trick", basically what we have is a palliative to sooth the pain of bad performance and irresponsible management. That is not a solution, or an improvement.

It's not bode well that in order to just play Odyssey we have to make so many tweaks and tricks... Frontier should give us a finished game. Instead they are selling garbage and asking us to figure out how to make this garbage some kind of manure. None of them smells good.
 
It's not FSR shame, FSR is like DLSS
The CAS option is last gen AMd open source tool, which isn't DLSS
I think at some point they mentioned that the two could be combined, eventually. Could be symmetry thing(?)
It looks vivid and defined to me. Definitely gives things a nice pop. It’s best to not think of it as an iOS along, as that is what FSR will be. This is more like an anti-aliasing method and definitely cleans up the edges. Elite had horrible jaggies and this is equivalent to methods used to enhancing and smoothing low resolution letters/ fonts/ images in Photoshop, by first applying a massive amount of gaussian blur and then applying contrast on top of that to smooth edges. And adding a bit of unsharp mask…by the looks of it. I’m sure it’s doing more than just that though. But best way I can explain it. It also appears that maxing this setting out isn’t the 100% solution, and seems based on your base resolution. As maxing this out at 1080p results in too much contrast. However at 4K you might be fine with maxing this.
