Nvidia's GeForce RTX cards have been a target for criticism since they launched last year, and while the RTX 2060 finally brings pricing down into the potentially affordable range, at $350 it's still a high-end card. With only one ray tracing enabled game launched last year (Battlefield 5), and one other game with DLSS support (Final Fantasy 15), the two marquee features have gone largely unused. It's not unfair to say that Nvidia has a lot riding on the Metro Exodus train, as it will be the first publicly available game with both RTX ray tracing and DLSS support. I'll dig into the details of both technologies and what they do—and don't do—for Metro Exodus in a moment, but let's cover some other details first.

If you haven't played any of the previous Metro games—and particularly if you didn't try playing them when they were brand new—you might not realize that the series has a well-deserved reputation for pushing hardware to its limits. Some might even argue that the developers looked at Crysis and said, "Yeah, we can make a game that runs like a turtle at maximum quality, even on the fastest hardware available." Given that history, it's not too surprising to see Exodus being one of the first games to utilize ray tracing.
