When it comes to perfect scenery ingame, then effects
play an important role. Now not all effects look great and
mostly they look too artificial. Movement of objects hasn’t
been perfect as in reality. Physics engines improved that.

But now there’s a tech demo showing how real weather can look like if the Unreal Engine 4 is used properly.

Watch the storm demo (1440p60) which has been rendered on a 970GTX at 35 to 60fps:

Now this really looks convincing. If games could implement storm scenes like that… wow, we guess that we’re going to see some marvellous adventures soon. Maybe even FPS games would implement that on some missions.

One would not even miss RTX features (Raytracing) as that scene looks stunning!
