AMD FSR antialiasing discussion

Something similar came out early June with Nvidia and Steam as partners bringing DLSS via Steam Proton.

 

Valve talks about FSR on Steam Deck:

Yup.

 

That's something completely different.

What you linked is just a capability support in translation layer, DLSS itself still needs to be integrated in game.

However, with FSR support directly in WineVulkan/DXVK/Proton via fshack you can apply it everywhere even if game/engine doesn't have FSR implemented.

 

Elite Dangerous has FSR added for players on the Odessey expansion. I'm on at 1080p screen, so it really doesn't help much on a game that has poor antialiasing options to begin with.

Might see if I can use DSR + FSR to perverse some image quality out of an upsample downsample bungfight

 

I think someone already tested this and you can (and in some cases might be even worth it if you tolerate FSR to begin with)

 

Video showing FSR vs TAAU upscaling in Chernobylite. Nothing too surprising, FSR Ultra Quality has the edge in performance but falls way beyond (IMO) in terms of detail compared to TAAU.

 

@Flappy Pannus TAAU looks more aliased upscaled, and FSR looks less aliased but a lot more blurred. Really going to come down to whether prefer sharpness with aliasing or blur with less aliasing. I'd probably pick TAAU, but I can see people picking the other way.

 

Sorry but what is gen 4/5 TAA I didnt know AA had generations?

 

Well, it can get better over time because they update how it works. The "gen" and "4 and 5" are rather arbitrary here, just meant to distinguish the two. First is older and does an ok job for cheap, second does a great job similar or better than DLSS, but is expensive to run.

 

UE4 / UE5?

 

Steam Lossless Scaling updated to use FSR:

Well, this is quite fun.

Force FXAA to game and then upscale, antialiased DOS games with decent scaling. (Though bit blurry.)

 

It will likely look rather horrendous.

 

640x480 games could look decent or games with already antialiased art when there is no need for FXAA to give gradients.

Wing Commander 2 and Ultima Underworld 2 looked quite blurry, although I loved to see AA on them.

 

DOSbox has several "HQ" res upscalers for many years now. They all look bad IMO and the best one is simple integer with no filtering.

 

Yeah, those are bad and yes, integer scaling might be best overall. (Will have to test someday.)
Haven't really found way to add AA when using any of them.

Would be awesome if one could force supersampling to software renderers.

 

AMD FSR Based on Modified Lanczos Upscaler, Can Be Enabled On NVIDIA GPUs Using Control Panel For Similar Results In Games
August 5, 2021

 

Heh, seems like someone discovered America again

We already knew that since source code release. For example:

TechPowerUp - July 15 - AMD FidelityFX FSR Source Code Released & Updates Posted, Uses Lanczos under the Hood
VideoCardZ - July 17 - AMD FSR and NVIDIA DLSS comparison shows similar quality and performance at 4K resolution in Necromunda Hired Gun
etc.

 

The fact that you can get a similar in IQ upscaling in any game on Turing+ Nv GPUs via a driver option isn't well known however.

 

It isn't a well known fact because it isn't a fact at all. The Lanczos kernel is neither a fixed parameter equation, nor is it the only algorythm used in FSR.

Is it surprising that the article is coming from Tom's "just buy Nvidia" Hardware though?
