You can render a high quality snapshot from the current view. Go to Tools > Render a High Quality Snapshot. In the pop-up window you can select the resolution and the Samplesfor the render. The more Samples you use, the better the quality of the render, but this comes at the cost of time.
You can also enable the Save as defaults option to set the current settings as your default.
Choose the output directory, name and format.
When the render is in progress you can Stop and save the frame with the reached quality, or Pause, or Abort the render.
