Hello @aleo13 ,
The medium quality preview is an intermediate effect.
Taking into account the preview efficiency, we will sacrifice some details when there is no rtx accelerated.

The RTX card will have a better experience and faster real-time preview, but in terms of rendering results, GTX and RTX are the same.
