people always make this stuff sound harder then it is. I said a long time ago MS would come out with two skus this generation. I said they could easily take the GPU in the 1x add a ryzen2 core cpu and make that the lower sku xbox. major blunder in last gen was the Jaguar cpu's they held the whole system back. get rid of them and you have a competent gaming machine.
Should I pat my self on the back now or later. I said that with the Ryzen2 cpu games would target 60fps as the standard. I was laughed at. Guess what MS appears to be using a gpu that is not even as powerful at the 1x gpu and doing exactly what I said. Execept going for 1080p-1440p instead of 4k since most people havent upgraded to 4k yet.
consoles are basically pc's now. especially the MS console. Pc's have millions of combinations of hardware that dev. have to program for. Why would making games for 4skus be so difficult? It wont and the lower skus wont hold the top games back. I can play the same games on my 970 that people are playing on their 2080ti's just at a lower resolution and some effects lowered or canceled. the dev kit will do most of the scaling work for dev. It has a button for each sku so dev can test performance
MS will come out swinging for the fences next gen so get ready gaming is about to be hella fun
and as far as raytracing goes its a fluid technique the hardware is capable they are just refiniing the techniques on how to use the hardware more efficiently the effects on framerate will get alot better once they perfect the software tricks. Look at the gains and improvements theyve already done with the few games that are released. it will only get better.
