Even if console's could manage proper graphs , it's controler vs keyboard mouse where the problem for multi platform gaming lies.
At this time pc players on a controller stil have there hardware .
PC gamers know that among equaly good players the best hardware wins .
A game like Rocket League is a good example of a well balanced game . To make multi platform work they downgraded graph's a bit for pc. And as a controller works best in a driving based sports game , no diverence there.
I hope to see more games like that in the futere .
