Fix the TAA for lower resolutions

[Radiant_Dawn]

I understand that the game engine relies on TAA heavily, but it's tuned only for the 4k resolution. I've got an RTX 3060 and a FullHD monitor, but I have to render the game in the 1870p resolution with DLSS and sharpening filter to obtain a quality image.

The current TAA implementation behaves destructively on lower-resolution render -- blurry image, dithered hair and beards unable to be restored by sharpening. It's better to use DLSS with higher-resolution render, than rendering the game natively -- 1870p + DLSS Balanced + sharpening > 1620p + DLSS Quality + sharpening > 1440p + DLSS Quality + sharpening > 1080p.

While there are a lot of other issues in the game, I personally consider this the most important one, since it directly impacts the player's experience all the time during the session. While I like how the game looks with DSR, it's still:
- A huge performance hit
- Even more huge on AMD/Pascal GPUs
- Forces you to turn off other options to get 60 fps (I had to turn SSR off completely)
- Not an intended way to render I suppose?

Later I'll pin some screenshots to compare.

I wish they would add FAA. So that textures wouldn't get blurry in the first place. Why would you make a game engine need a setting forcefully on to work.

I'm not 100% sure, but I think TAA is necessary for the engine and DLSS to work. Remedy's Control has got similar issues, though its TAA is somewhat better and is somewhere on the edge between "soft-looking" and "blurry-mess".

The problem is that textures look pretty sharp even with DLSS on (once you set negative LOD bias in the Nvidia Inspector), but hair, edges, moving details are mess and unrepairable by any filter or setting except DSR.

The current TAA implementation behaves destructively on lower-resolution render -- blurry image, dithered hair and beards unable to be restored by sharpening.

The dithered/pixelated hair is the biggest problem I have. It ruins the screenshots on 1080p if some detailed hair is present. And sure, I can use DLSS, but the game becomes extremely blurry and loses detail.

Screenshots, as I promised. Made while moving to see how TAA actually works in dynamic, motion blur disabled.
- FullHD with nothing
- 1440p + DLSS Quality + Sharp 25%
- 1620p + DLSS Quality + Sharp 25%
- 1870p + DLSS Balanced + Sharp 25%
- 1870p + DLSS Balanced + Sharp 40% (current setup of mine)

One can see a gradual progress from absolutely horrible in FullHD to acceptable in the higher-resolution setup. The last looks actually pretty cool in-game, but if you set DLSS any higher to enable raytracing or something, this will be a huge quality drop.

guys, i have a problem (but cannot create new thread),
This is a screenshot of the 2nd run i just startet. ich have these grafic issues, which i havent had the first time. can anyone help me?
