Alan Wake 2 analysis really shows how far ray tracing tech has come

Alan Wake 2 is not only a great horror game; it also looks pretty. While it’s not always about what something looks like, a recent video really hammers home just how far graphics and graphical technology have come over the years.

In the most recent episode of Digital Foundry, we get an analysis of Alan Wake 2, with particular reference to its use of ray tracing (RT) and path tracing (PT). Side-by-side comparisons really demonstrate just how effective algorithmic-based tweaks can improve the look of a video game.

For example, we can see that without ray tracing, small details are lost, such as sharp shadows, accurate reflections, and some general degradation in global illumination. We can then see that with RT and PT on, there’s a noticeable difference in visual acuity.

However, it’s by no means perfect. The DF video is a little critical of Alan Wake 2‘s inability to use path tracing to its fullest. The analysis suggests that native global illumination is likely overstepping on any attempts for the PT tech to make improvements, which we see in certain reflections or lighting. It still looks great, but it seems clear that the game could make improvements to path tracing to make it more effective.

So why does all this matter? For many gamers, it’s probably not too important whether a shadow has sharper clarity or windows reflect the condiments of a diner. However, for more graphical purists, especially those who are using top-end AMD or Nvidia hardware, many will want to get the most out of their system. Ray tracing, path tracing, and image upscaling AI are pretty much standard these days, and it’s nice to see that extra bit of work go into making a game look incredible, especially when you consider the price of graphics
