My bad, you are correct. I leave in game render scaling at 100% when that option is available, using TAA antialiasing. If I choose to use DLSS then the scaling will change depending on Quality, Balance, Performance settings etc.
This sim can change from day to day, especially in VR, so depending what I’m flying and where, I still change my settings to suit what I’m doing and how well things seem to be working at that time.
