Look at Steam hardware survey, you will find that over 60% of the users have systems in par or slower than the current XBoneX and PS4Pro.
So I do not believe we can talk in 2020 for weaker consoles. Let alone the upcoming behemoths which class 98% of the PCs out there. Including all those having 2080 or bellow GPUs.
All games were designed to run on the weaker original consoles:
[email protected] with 1.31TF of power (the weakest CPU from PS4 and weakest GPU from the xbox). Xbox X and PS4Pro were 4k wannabe hw, not 1080p@30fps, new consoles, with games
specially designed for them.
Moreover, on the Xbox Series X, Microsoft plans for the next 2 years to have all their games run on that 1.75GHz, extremely weak CPU, and 1.31TF GPU, making that behemoth stuck within the same limitations as now. Sure, you'll get higher fps and higher resolutions (stuff which you can do now also anyway with a decent PC), but the
gameplay is still the same.
Even older Sandy Bridge or FXs CPU would be stronger/faster, while that gtx 1660 5tf card would destroy everything that's in the original consoles.
So yeah, if these 2 new (behemoth) consoles would have been 1080p@30fps targeted, that would have meant a big jump in terms of visuals ( they may be still 1080p cards when it comes to RT, although in this case the visual jump may not be as impressie)- and perhaps even gameplay. But right now they're just joining the 4k (60fps) game for a while -> 2-4 years down the line and stuff like dynamic resolution, under 30fps drops and so on, would be the norm.
The thing I'm most exited about is the CPU and a bit about the SSD (but not for the over hyped reason Sony is making it to be) -> at least we'll get higher quality assets all around, physics and hopefully AI.
