Parsing hardware requirements is very much a matter of interpretation.
Take Limbo for example [url=Limbo]https://www.gog.com/game/limbo[/url]. The graphics requirements are
5 years or younger. Integrated graphics and very low budget cards may not work. Shader Model 3.0 required
This means 2015 or newer right? SImple enough, other than the fact the game was released in 2011.
Then there is the
The Witcher Adventure Game
2.0 GHz Dual Core
1 GB RAM
Integrated Graphics (512MB)
My Pentium D 805 from 2005 is a 2.66GHz dual core. It comes with 945G integrated graphics. That must be good right?
Even assuming every developer gave sensible inputs to the filter, keeping it updated would be a nightmare.
Every year, games will move progressively down the requirements hierarchy as more advanced hardware is released - the older your computer is, the less relevant their filters become.
Then there are the games that stop working on newer hardware. Apple's dropping of 32 bit support caused much wailing and gnashing of teeth.
Honestly, if such a thing were feasible, Steam would have implemented it by now.
