Not that it really matters but this is not the first game that requires ray tracing to run. Though I do believe its the first triple AAA game to require ray tracing as a minimum. There have been some indi games like Stay in the Light that are not only built with ray tracing as a minimum spec but also have ray tracing as a core part of the gameplay.to my knowledge this is the first game that says you need hardware ray tracing acceleration to run it - there is no ray tracing off/rasterization fall back option. For those who don't meet the minimum spec, you won't be able to run the update
Stay in the Light – Ray Traced Horror (sunsidegames.com) Looks like it is now a free download?
