Its not just for games though. Its a great development for developers and its great for end consumers like me that like to mess around with Ray Tracing at home. It could also benefit those without ray tracing cards. Many of the faked pre baked shadow and light effects in current games are done via Ray Tracing in development.All very clever and no doubt Nvidia will sell loads of Turing cards to the gullible, thinking that their games will now look like this, and I'm sure that one day they will, but its going to take numerous generations of Nvidia RTX cards before they come anywhere near that.
Take the game development engines Unreal or Unity for example many devs use Ray Tracing to setup all the lights and shadows and once they have it looking good they pre bake it for games. Having a good RT card in development will speed this up and allow more time to be spent on getting better lights and shadows setup up for none RT games. As D.P. said better RT is great for content creation. Even if you do not use RT directly you should see the benefits from it.
