    It gets problematic for “AI” & raytracing stuff.

    Why is raytracing sought after? Wasn’t there an article recently that its really only effective when used on old games? To be honest tho, I have no idea what it even is or does and have never noticed a difference in a game using it or not using it.

      Because you can get actually accurate lighting, shadows and reflections using ray tracing. Not sure why it should make sense only for old games.

      Ray tracing renders things similar to how our eyes perceive light. You can look ups some rasterization vs ray tracing videos to get the gist of it.

        I’ll try and find the post from a couple days ago that had an article about it. I only half read it because I wasn’t overly interested reading about games I don’t for see myself playing/playing again. The article was specifically about this tho and why I even asked.

      It’s mainly to do with lighting and, while they are going and adding the tech to old games like Quake, Minecraft, and Doom, it is mostly a “future” tech that will hopefully take over other types of lighting in games the more accessible it is.

      This is simplified but it adds more realistic lighting by actually having the different “rays” of light actually bounce off of and reflect surfaces much more accurately, more more computer intensively, than other lighting methods. There are a lot of RTX on/off videos out there, if you have a decent monitor you can tell the difference.

      Right now Nvidia has better raytracing performance because they have dedicated cores for it, whereas AMD has raytracing but they’ve been playing catch-up to Nvidia.
