To be fair you are kinda right, a lot of PS3 games just got stuck on that platform until Sony figures how their own hardware works. I want to play games Siren but welp.I made like 8 points in that thread, all 100% correct. You start your response with 'bullshit' is if that negates it.
Developers aren't targeting "thousands of possible hardware configurations". They're targeting the x86 CPU standard and some graphics api like DX12, DX11, Vulkan. Often they're not even going that deep, instead targeting mature portable engines like UE4 and Unity. There are many games that launch in a shoddy state, but there aren't many games still in that state, shit gets fixed. Meanwhile every game from the PS3 era that was ported to PC runs in 4k and generally holds up nicely. Games from 2005 running on PC don't feel retro, they have perfect image quality and unlimited framerate on any GPU in the last few years.
Rooting against PC is rooting against yourself. Any fleeting issue with PC gaming is nothing compared to preserving by far the biggest library of games going back to the 80s. PC (w/ Steam) IS gaming, while every console is just an incomplete reflection of gaming at some point in time.
But nowadays games hardware are more streamlined than ever. So it doesn't matter that much.
