Their claim does have support in so far that the early testament contains a lot of work written by polytheistic people that later in would become the monolatrists and even later monotheists that we know as Jews, further branching off into what today are Christians.
This does not mean that Christians in any sense are not purely monotheistic. Not only are they so, it’s one of the most critical parts of their beliefs, to the point where even believing that their one god has in any way shape or form some kind of tangible division is considered strict heresy from trinitarian churches which form the mainstream of Christianity and have done so for hundreds of years.
Edit: There is a great video by Alex O’Connor interviewing Esoterica on that topic in particular and they talk about the evidence that supports the viewpoints.
Where is RTX being forced into? Haven’t seen a game where it’s not an option you have to toggle on first and it’s not like RTX is a lot of additional work for the developer, seeing how it in fact reduces the work necessary to make a scene look the way it should.
Yes, it’s stupidly expensive and not every game manages to benefit massively from it, but it can lead to some very pretty environments in games and it seems perfectly valid in those cases.
Also, some people do quite enjoy admiring the way the materials of various things end up looking. Maybe it’s not the majority of players, but some people quite like looking at details in the games they play.
