So, i made a separate guide for potential stutter and performance fixes, check it out here!

That guide also helps improve my fps with some config file changes, really recommend it!

*Notice*




There are two ways to do this, one with DLSS Swappper (easiest and will backup the old dlss files automatically). This can also upgrade your other games with ease incase you have other games that uses DLSS.

Firstly, download DLSS Swapper (simplest and you can update all your games if you want): https://github.com/beeradmoore/dlss-swapper
Download the latest version, its just simple install and also a portable version if you don't want to install
https://github.com/beeradmoore/dlss-swapper/releases

Then proceed download the latest DLSS in Swapper (Currently 3.1.1 as seen in picture)


Next, go to games and find Hogwarts Legacy, now click it and choose 3.1.1 (the newest as writing this guide, may be newer ones later, choose that then)


DONE


It will now use the latest to get better performance and quality (the old will be back uped)

Or you can do the method below

You can also manually replace DLSS file from here: https://www.techpowerup.com/download/nvidia-dlss-dll/

Download the latest and replace the old one located here

"steamapps\common\Hogwarts Legacy\Engine\Plugins\Runtime\Nvidia\DLSS\Binaries\ThirdParty\Win64"

Be sure to have the game turned off or restart it afterwards

You can also update the DLSS if you use a Nvidia 4xxx series card

This file is called DLSSG. You will do the same thing as the method 2, but the location for DLSSG is in another map
"steamapps\common\Hogwarts Legacy\Engine\Plugins\Runtime\Nvidia\Streamline\Binaries\ThirdParty\Win64"

This if for those using Nvidia Frame Generation. It can be downloaded here:

Does this work for AMD GPUs?
-No, closest would be to use FSR 2, it can't be updated tho.

What happens if game update?
-They could update the DLSS file or revert it. Check it after updating and see, you might have to apply it again. However, usually in most games its never updated and you have to do it yourself, it could take long long long time before they decide to update it, if ever since its easy to do yourself

Does Nvidia Drivers update the DLSS?
-No it don't, only the Devs when updating the game or YOU can update the DLSS. The devs and game are often gonna be behind on updates for DLSS, you will always get the latest with DLSS Swapper or by the manual method

Which DLSS preset should I use?
-Start with quality and feel if it feels smooth and ok. If not move on to the next preset until you are happy. It's a matter of quality contra performance and its only you who can decide what you are happy with. Quality=Better quality and Performance=worst quality but better fps

It looks blurry?
-Just upper the sharpness filter under preset a tad

How do I check which dlss version I have currently?
-Right click the dlss file in your hogwarts directory as mentioned above, then properties > information and you can see file version of DLSS

I get some kind of error
-Easiest is just to replace the backup file of DLSS that Swapper made, or just verify files in steam by right clicking the game in steam. Changing DLSS in Hogwarts should not give you any problems tho, i would suspect something else to be wrong since 2.5.1.0 is tested by many now and by me without any error for hours

How do i download Swapper on the github page?
-Look to the right where is says "Releases", also be sure to follow their install guide

Simply replace the backup file for DLSS which Swapper did in the same directory. You can also just verify the game cache in steam by right clicking the game in steam.

This should not at all break your game if you done it right. Its tested for many hours and i've myself been using it since start with 2.5.1.0. If something should break its probably that you've done something wrong or something else with your system.
