The last time it failed it was supposed to come back with allowing modules instead of parts. Apple would be fine with selling “modules” as they consider their devices to be top case, bottom case, motherboard, battery, and screen (has stuff attached.) If they can have a needs calibration some where to shame 3rd party repairs and not allow board level repair it is just what they wanted.
Ray tracy can be cheaper for equivalent lighting quality than rasternization. Depending on how they use it, it could be great to have rates and only just like how mega texters work. People got upset about the g p u memory requirements for mega texters , but it was a huge gain in performance if you hit the minimum. Retracing as an effect on top of rasterized ighting is a big hit to performance and the only thing we have now.
Native real-time ray tracing was released like 20 years ago with ati x1000 series. No one wanted to risk making a retracing only games so it never took on. Rtx is based on using ray tracing as an effect to go on top of rasternized graphics.
No current games use retracing only, indiana jones uses it for mandatory effects and not as the primary render method.
