For Hogwarts Legacy players, this guide will show you how to allow forcing DLAA and choosing between different DLSS3.1 presets
Wrapper DLL that can force DLAA onto most DLSS-supported games, along with tweaking the DLSS 3.1 presets used by them.
To install just extract dxgi.dll & dlsstweaks.ini next to the games .exe file ( steamapps\common\Hogwarts Legacy\Phoenix\Binaries\Win64), and then edit dlsstweaks.ini with your desired changes (ForceDLAA etc)
(the default INI won’t make any tweaks, you’ll have to edit it first)
Like this (choose preset in FAQ section, or type F in [DLSSPresets]):
With ForceDLAA active all DLSS levels will act as DLAA instead, rendering at full-resolution with DLSS applied to it.
The game might be changing mip bias depending on DLSS level, so feel free to experiment with them.
If you want to verify whether DLAA is active you can use the DLSS dev DLL, the INI file mentions how to set that up.
It’s recommended to use this with DLSS 3.1.1, so that the DLSSPresets section can be used (2.x should still work fine, but DLSSPresets won’t have any effect)
You can find 3.1.1 at techpowerup: https://techpowerup.com/download/nvidia-dlss-dll
Download the latest and replace the old one located here
Be sure to have the game turned off or restart it afterwards
