Due to marketing b*******, most things labeled as 3G are actually 2G.So networks don’t support both two and three g. Then things that are actually 3G like hspda and L.T.E are marketed as four g , so it’s just very confusing between all of it. They want to shut down the 2G.Networks that are edge and gsm.And they want to shut down the one g network that’s cdma. Depending on your service that could be marketed as 123 or even four g.
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.
