The problem with the always on Raytracing is that the RT engines in everything but the current gen GPUs induces a lot of delay. The GPUs are constantly waiting on data, which leads to a lot more hitches and radically limits top level FPS. I also really question how well it runs on laptops with Nvidia GPUs, because of that issue. And, in an era of high refresh desktop monitors, not being able to get it over 120 FPS seems odd.There's another problem, Denuvo. Took Eternal 3 years to remove it. Given the steep spec requirements, that's not gonna bode well for sales down the line.
It is actually a very well optimized engine, but the game needs to run on a NVMe drive, as well. So it's going to have a lot more people unable to run it well, which adds up on discussions. And they're used to the iDtech engine doing like 300 FPS if you turn everything down, but that doesn't work with always on RT. It's more of a Console type of game, as a result, functionally.
Even with all that, the blow up with Mick Gordon is the elephant in the room. It killed the hype before the game was released. There's a whole world of "offline vibe networking" people have forgotten how to understand exists.
