WHat is Fidelity FX CAS

[Viper]

ANd should I be using it on my GTX 1080ti

Hi, i wondering as well. It SEEMS to lowering the internal resolution giving you the "sharpness" control of it. Im not sure. I looked for on the internet but i cant find a real answer. I would like to increase the sharpness of the game at 1080p, but this really lowering the quality of image. Also i think this lower the internal resolution due to increase the performance of the game. I seen Fidelty fx cas on Monster hunter world and same results, lower image quality better performances. I would like to know at least HOW mutch this decreases resolution. No way to increase a bit the sharpness without lose internal resolution?

Its meant to be used for 4k not 1080p dats why it reduces resolution

This make sense. But there is some way to increase sharpness at 1080p? the game feels a bit blurry sometime unlike other games that are sharp at 1080p. I guess maybe is the bad implementation and low quality of blur system, or TAA foult.

Fidelity FX CAS is AMD's response to Nvidia's DLSS. A simpler implementation of the same idea not restricted to specific hardware.

I am going to be running 1440p.

You can try the nvidia control panel for sharpening. Imo sharpening is overrated though and for this game, i feel it makes it look worser without some blurriness

I dont think so. DLSS reconstruc the image to simulate higher resolution without the performance cost of native. Fidelty FX just lowering it (for better performances ?)

okay thank you. It was off by default. I will leave it there.

It renders at 75% resolution, then applies a sharpening filter. FXAA or TAA can be applied on top of it, since it's not actually a form of anti-aliasing or image reconstruction. It's purpose is to boost frames a bit at a slight cost in visual quality, mostly for lower end systems

Ye. i agree. Like no anysotropic filtering setting is meant to masquerade the "repetition" of texures on the distance.

Fidelity FX does multiple things. The implementation in this and Wonster Hunter World is the same basic idea as DLSS. Run the game at a lower internal resolution with sampling to smooth the image and an adjustable sharpness setting to try to mitigate blur.

Not exactly. Both render the game at a lower resolution. DLSS 2.0 uses an AI algorithm and previous frames to reconstruct the image at your output resolution. Fidelity FX Cas only applies a sharpening filter. It's also hardware agnostic, and can be run on both AMD and NVIDEA cards. It is not an image reconstruction technology though, and it will not boost performance as much, as it is rendering at a higher resolution than DLSS 2.0 (75% vs either 50% or 66%, depending on if you're using Performance or Quality mode)

I'm not trying to say it's the same technology as DLSS. That would be idiotic.

But: The basic idea is the same. Running the game at a lower internal resolution with filters to smooth the image and bring sharpness back up.

Being hardware agnostic is the ENTIRE point of the technology as compared to DLSS.

They serve the same function.

They just accomplish it slightly differently.

You should use Nvidia Freestyle (Alt+F3), or Reshade to sharpen up the blurry 1080p TAA.

CAS basically renders the game at 75% resolution and then sharpens it, so you get a slightly fuzzier game but more FPS.
