big doubts with the dlss 4

[signo]

I have always updated the dlss to the most recent versions by manually replacing the dll file, but now with the dlss4 and the nvidia app update how does it work?
the only native game with dlss4 that I have is cyberpunk but I'm not understanding.
if I replace the dll files (going from 3.8 to 310.2) is it enough to directly activate the new dlss, do I have to set it directly from the app and no longer have to replace the files, or do I also have to replace them to ensure that it activates correctly?

There's a much easier way to do this. Download the latest version of DLSS Swapper, it scans your games, then you can just tell it to swap in the latest DLSS files for you.

thank you very much I will download it, but still the question remains.
to use the new dlss just replace the dll files, do I have to set it from the app or both?

You will see, in DLSS Swapper, that the version for the DLSS that the selected game is listed, but can be upgraded or downgraded to whatever version you want. There's the general DLSS version, the Frame Generation version, and the Ray Tracing version. Normally you want all three of those to be the same, i.e. 310.1. You can experiment with newer versions.

Once you're in the game, as long as you have the various DLSS/frame gen/RT options enabled, the game will use the selected DLSS version that you chose. It's that easy.

In addition, some are claiming that you need for force the Preset type that DLSS uses. In CP2077's case, making sure Preset J is used is probably best. I don't know if the game chooses Preset J properly on its own or not.

To do this, you can use Nvidia Profile Inspector and force Preset J for your DLSS. It's recommended to set this in the "Global" profile. Just Google the subject and you should see it discussed in i.e. Reddit.

ok so already by changing the dll files to the latest version you are already using dlss4 with its improvements, but it doesn't always use the j but k setting and I can set it with the override option from the app for supported games, or via l 'app you're telling me.
right like this?

As long as you've got the proper files in place, and you're selecting Preset J, then you should be enjoying the benefits of the newer DLSS, yes. Remember, however, that DLSS 4's entire point is to use the Transformer Model in the game, so make sure that's set as well.

It's also possible to use DLSS Tweaks to get an overlay in the game confirming Preset J is indeed running, but getting DLSS Tweaks to inject properly into this game can be frustrating.

The differences are hard to see. Most people are simply reporting much better performance, especially when increasing the DLSS Quality level (in-game), usually not suffering any performance loss now by doing that.

Lastly, there is an even newer DLSS version now, 310.2.1.0, which uses Preset K. If you switch to this version, apparently Preset K is automatically selected. I haven't seen it make any difference in CP2077 from 310.1.0.0 / Preset J, however.

Crispy, you're making it overcomplicated. Don't need to download anything for cp2077. Just open the nvidia app and select graphics/cp2077/scroll down to;

DLSS Model Presets==change to same settings for all dlss techs==Latest. You're done dude.

Mine is using the following in game after doing that as pic below.

DLSS FG=310.2.0
DLSS RR=310.2.0
DLSS SR=310.2.1

My files in cp2077 folder are 310.1.0

Now if you want to over complicate it a tiny bit to force model presets do as such;

DLSS Model Presets==Use different setting for each/scroll down to Super res and change it to A-F or J note latest is K

Now if you want to over complicate it a lot more download nvprofileinspector 2.4.0.8 it's the only version that works atm as it's the newest. You can then override 10 dlss settings. But you still don't need to download any new dlss files as nvidia will always do that for ya.

Now some games you can't override unless you change the white list which you can btw. But now we're talking ever more complicated. Ya i do them all. I probably should have not written these last 2 paragraphs. lol

but so does it still make sense to replace dll files in game folders?
meaning, if for a supported game like cyberpunk I don't enable DLSS Model Presets but only change the dll files what happens?
Is this what if I set directly to preset j?
because on cyberpunk there is the possibility to select ccn or Transformer, but on the other games no, or at least not from the game like cp

[signo]

I'll give an example
the only game I have installed in which there is obvious ghosting with dlss active is metro exodus ed.
by replacing the dll files with the most recent ones the problem was greatly reduced but still somewhat present.
However, if I go to set the preset via DLSS Model Presets the problem disappears completely.
therefore, replacing the files is no longer useful, it is useful but not as good as setting the DLSS Model Presets?

Replacing files is only good now for games that the nvidia app doesnt support else your just fine

ok so let's say that replacing them is one more thing but to do it well in supported games it's better to set it from the app

[Crispy™]

My advice was obviously meant for people, like me, who refuse to use (and detest) the Nvidia App.

i always use dlss swapper since its easy to use and you can update frame generation an ray reconstruction aswell, not had an issue since, only multiplayer games you should be wary off using dlss swapper.

I too have never had problems replacing the files, the doubt was the difference between just replacing them or setting the dlss override from the app

Yes, for supported games the app is better because just updating the files wont give you automaticly the new Transformer Model (except you use something like DLSSTweaks) but with the app you can force it by selecting the "J" or "Latest" Profile
