I don't know about OP, but I've got a pretty powerful PC, and Windows loves to suck up unnecessary resources. The Desktop Window Manager (dwm.exe) routinely uses 1 whole GB out of my 8 GB of VRAM. That's not cool. So I have to go through a bunch of settings windows then tell windows to turn off all of it's hardware accelerated graphics rendering features for the OS to get dwm.exe to consume a more reasonable (I guess...) 250 MB of my VRAM. Not only that, but windows anti-virus scanner runs all the time and routinely consumes about 20% of my CPU for no reason. I have yet to find a way to turn that off for a specified time period. Consoles are built for games, so you can safely assume they're not going to consume unnecessary resources and tank your games performance. Games are (usually) built for consoles, so you can safely assume the game will be able to utilize the hardware much more efficiently than your PC that it has no clue about all the hardware/system specs. That's just a couple reasons I can think of for not being able to just play a game on your PC, and I'm sure other people have more examples.
