No matter how many PCs with new hardware he buys, DPC will not be able to jump above his head. Before you can set the scene to render, you need to create it and the most difficult part is posing. Even if his computers are very powerful and the render queue is empty due to this, DPC will spend time preparing renders and animations. In the case of a further increase in new episodes, the development time will increase. It's easier to deal with it.
So far, I don't see any prerequisites for the game to be abandoned. Typical symptoms are writer's block, lack of feedback with subscribers. Seriously, all this guy did was take a two-week vacation once in 5 years.
And ofc AMD cards not suitable for DAZ, because rendering on the Iray engine, this is Nvidia technology. Well, Intel cards ... it's a pity to even joke about them.
