Good point. Still, games running well on consoles and running like shit on PC (e.g. Batman Arkham Knight), PC games that are horribly optimized for lower spec rigs, or PC ports that pretty much look the same like the console versions are aplenty and should be considered.
You are picking at the minority rather than the massive abundance of games that work exceptionally - BAK being the first game on PC (ever?) to be removed from digital sale due to such hilariously woeful issues. And if we are going into the "horribly optimized for lower spec rigs" argument, I am more than happy to argue against that - happily (well almost) chugging along with a 4 year old laptop and playing the latest games above 30fps at the laptops native 1366x768 resolution. MGS V, Wolfenstein, Alien Isolation, GTA V etc, no problems. Obviously I'd rather have a better system, but I am waiting for the right cases and components to release next year before moving on since the laptop is still doing well enough.
