If you still remember the time when DLSS 1.0 was just coming, then Nvidia presented the possibility to use this AI upscaling filter without scaling itself, in native resolution, which was then called DLSS 2X. This version, which would not improve performance but only image quality, appeared years later as DLAA. It hasn’t been available very often in games for a long time, but that’s changing now and it could be everywhere that has basic DLSS 2.x.
Nvidia has now released a new version of the DLSS 3.1.13 libraries, which, among other changes, also bring a new preset between the quality (and performance) settings that DLSS 2.x now offers – i.e. the Quality, Balanced, Performance, Ultra Performance options. These pre-existing options all include upscaling. Newly, the DLAA mode will be added to them, which will be a special option in that it does not contain upscaling and should therefore be free of most of the artifacts that can arise from upscaling.
We described DLAA back when this filter appeared as a specialty in Bethesda games:

It is actually DLSS 2.x running with a scaling factor of 1x. The graphics card counts frames in native resolution, but the rest is already the same. The images are taken as input by a neural network, which applies its usual learned effect to them. Thus, DLAA in native resolution works as smoothing replacing TAA and performs related temporal stabilization, for which motion vectors are used as in upscaling.
Theoretically speaking, the image with DLAA should have a higher quality than with all DLSS presets – it will be free of any quality losses that the lower real rendering resolution could have caused – and take only the positive from artificial intelligence. But strictly speaking, problems are not excluded, because AI postprocessing, like everything, can have negative effects outside of upscaling). While it is quite debatable with DLSS, with DLAA it can be expected that the image quality should always be better than the native resolution, with some unusual exceptions.
The downside, of course, is that due to the native rendering resolution, you no longer get any of the performance gains you were used to when using DLSS as upscaling. FPS should be slightly worse than without DLSS due to some computational cost.
Principle of operation of DLSS 2.x
The fact that DLAA is now among the standard presets for DLSS should mean that the technology will be available in all DLSS games that are built on sufficiently recent versions of the DLSS libraries. In older games, if the developers do not update them, this will not be reflected. But you can try to manually implant the newer DLSS libraries (3.1.13 and higher) into them, which might make the DLAA option appear in them as well.
