Well, the reason for the change implies the player doesn't know how PC works... which would make sense if it was a consideration for a console... however in ps4 warband the size is just locked at the point before it would effect performance but has a a slider. Then again with multiple versions of systems now and possibly desire for multi console release (ps4, ps4 pro, ps5) an option with out a hard lock might let you make 1 version downloadable for multiple systems.
I like to use the slider to manipulate how many annoying horse archers I fight at once so I'm sad to see that ability go.
