Can't say I have noticed any performance drops after patching to 1.6. Did a ~10 minute test just now, and I still get between 75 and 90 FPS (according to RivaTuner) when driving around in City Center, which should be one of the most resource intensive places. Was during the night, with less pedestrians, so not a truly worst case scenario.
I haven't gone over the graphics settings to check whether anything has been changed automatically without my knowledge after the patch, but while I could be wrong as I haven't played CP77 in awhile, I get the sense that the object draw distance has been reduced since patch 1.5 Hotfix 1. Though this should only improve the FPS.
Playing at 2560x1440, with both RTX and DLSS OFF. Playing on custom High settings, with reduced shadow quality.
