I realized that if you activate RR , even on simple ray tracing or on path tracing , if you select DLSS it will be forced always on Balanced level (don't know maybe Performance?)
Just to make an example : My resolution is 3440x1440 and the output resolution shown from DLSS indicator was 1720x720
It doesn't matter if you change it under settings or if you force it via Nvidia App, it will be always set like that
If you turn off ray reconstruction then you can change DLSS quality without problems, it will also ovverride DLLS model from what you choose on Nvidia app
