For some reason, Larian shipped an old version of DLSS with the game. It looks better if you swap out the DLL for a newer one. I use DLAA on my 3070 TI and it looks good, but I did have to swap the DLL.
You can either use DLSS Swapper or manually download a new DLL and drop it in yourself. It’s essentially just replacing the nvngx.dll in the game’s directory with a new one.
There are some issues, though - for example, upgrading from a version prior to 2.5.1 will disable the use of the sharpness slider. I mitigate this by using DLSSTweaks to force preset C, which favors the newest frame more heavily.
