If the base model does 2k at 6 tflops and the pro model does 4k at 12 tflops, what's the problem?
It isn't about resolution because gpus can be used for lots of different tasks, as can a cpu.
Think of the base spec console as how much money you have to build a house (computing power = $) . If you have $100k to budget, then you have to work within that. The type and style of house is up to you, the developer. You want maximum sq footage, or do you want super energy efficient, or cutting edge style?
With game dev, you need to ask how much you want to spend on AI, object permanence, interactivity, world size, etc etc. But all of it must fit into your base spec because the game (the actual gameplay) has to be the same on both machines. You do not build two games.
So you build your $100k house. The pro version of that house would be you taking the base and then spending another 100k on exterior superficial stuff like landscaping, garden gnomes, etc. The house is still the house. You dont get to take the extra $100k and build a better, different $200k house.
The pro version of the game is merely upping the rez, fps, AA, etc. The game is still the game. You don’t nt get to build a better, different game with the extra resources available..
