My monitor has a “Super Resolution” Mode. It more like super sharpening. 
When I have the renderscale aroung 65 to 70 the scenery looks almost a bit oversharpened but the glass cockpit displays remain kind of blurry. What is strange in my opinion is, that the non digital cockpit gauges look fine…only the glass displays are blurry. Well…seems I have to live with it until prices for graphic cards come back to normal.
