Nvidia debuted real-time ray tracing with its RTX 2000 Turing GPUs in 2018. While it was limited to a handful of games and the implementation was shoddy, Nvidia is now celebrating around 500 games and apps that support ray tracing. This number might seem huge, and even if you aren’t a prolific gamer, you’d agree that ray tracing is far more prevalent and evolved than it was five years ago.
