Exclusive: Metro Exodus Enhanced Edition Analysis - The First Triple-A Game Built Around Ray Tracing

Real-time ray traced reflections are an impressive trick, but real-time global illumination is where this tech shines IMO. This Digital Foundry video ( [VIDEO] ) is a good overview of why this is such a huge leap forward for developers and players alike. Metro: Exodus EE (the game discussed in the video) is the only game I've played that really shows what 'RTX' and similar GPU hardware is capable of, IMO. Even CP77, which was supposed to push modern systems to their limit, feels like its ray tracing and GI stuff is janky and tacked-on.

Metro Exodus Enhanced Edition uses RT for basically all lighting, doesn't it? [VIDEO] Same with Minecraft RTX [LINK] Though both still calculate the lighting over several frames, so if you want to be pedantic you could argue that it's not strictly real time.

Here is a good video by Digital Foundry looking at Metro Exodus Enhanced edition with devtools. Where they show what raytracing is and how it differs from regular lighting. [VIDEO] simplified tldr: with raytracing you build the environment, designate which parts (like sun, lamps) emit light and you are done. With regular an artist has to spend hours to days adding many fake lightsources to get same result.

There's also Metro: Exodus, which the developers have re-made to only support RT lighting. DigitalFoundry made a nice video on it: [VIDEO]
