Yeah, he's just a grifter. And I use the term intentionally as he's way too purposeful for it to be purely the product of ignorance/ego.
I gave him the benefit of the doubt initially, but no question in my mind at this point that he's just weaponizing gamer dissatisfaction to line his pockets.
He's very good at creating a perception of meaning in content where none actually exists; for example in the video his first thing is saying that a certain element of the pipeline takes a certain amount of time, and presents it as if this is time wasted. However he follows this immediately by saying you can't remove this because it breaks the rendering and asserts they (Warhorse) could do this elsewhere. Which is clearly a false argument as the way he presents it he doesn't have to explain the effect of or quantify the cost of of shifting the workload elsewhere in the pipeline!
