Well, it's true that the proportion of games that have ray tracing -- over the space of all games released -- is small. But most triple-A games seem to have ray tracing these days. Of the last four such titles I've played three had ray tracing (Resident Evil 4, Jedi Survivor, Hogwarts Legacy). I think that's only going to become more true in the future, as IMO it does materially make an image quality difference.
- ehnto 3y agoThey had the technology but not the power, so most games still only had bits and pieces using ray tracing and were not globally illuminated by it. Not to mention you have to make the game work on old equipment too. That means all the downsides of old lighting techniques remained and none of the art efficiencies are realized. We are at the third generation of cards with RTX and there are almost no games using ray traced global illumination, and even if they do they still have to offer rasterized lighting for older hardware.
- yazzku 3y agoWhat do you mean "almost no games using ray traced global illumination"? The games mentioned above and many others are using ray-traced shadows, reflections, and sometimes one bounce of (diffuse) light. Not full path tracing, of course, but these techniques are still considered "ray-traced global illumination".
- ehnto 3y agoOnly the bounce lighting would be considered global illumination in my understanding, and that still requires other rasterized techniques to make a fully illuminated scene.
