DLSS reduce significant the power consumption and thermal load from your RTX card.
It costs here and there quality f.e. clouds at distance.
Therefore i did experiment with some settings in the Nvidia control panel shown at the video start.

I noticed the capturing with 60fps while running game with 58-60fps max cause sometimes little stuttering in the video. Next time i set game fps a little higher.

Alternative of using DLSS i tried DLAA without upscaling.
