One of Nvidia's research team members Morgan Mcquire claims that by 2023 you will need a ray tracing GPU to play AAA games. Makes sense since by then there will be nothing but ray tracing cards on the market and even if high end games don't require ray tracing GPU and non ray tracing GPUs would be pretty old and too weak to run them anyway. I wonder when and if integrated graphics cards will every get ray tracing.
I predict that the first AAA game to REQUIRE a ray tracing GPU to run will ship in 2023, and every gaming platform will offer accelerated ray tracing by that year. #SIGGRAPHhttps://t.co/orlS2Ka51Ypic.twitter.com/lETomAM9b7— Morgan McGuire (@CasualEffects) July 28, 2019
I think ray tracing gets most of its hate from the cost of the Nvidia RTX cards especially the 2080 ti but they will get cheaper once AMD and even Intel come out with their ray tracing GPUs. That means we should also be seeing even more ray traced games since AMD and Intel will also partner with developers to implement ray tracing into their games too.
Developers like Quantic Dream also say its going to be huge and are already looking into for their games. Ray tracing is easier to implement than the methods we have now so other than the performance hit which will eventually be fixed as we get newer generations of cards I see no reason for devs not adopt it.
