Doesn't really make any sense given its the exact same engine as GTA 4 & 5. Aren't those games also all developed with the PC as a base because the 360s hardware was basically a PC and it was easier that way. The last time Rockstar release a game that wasn't optimized terrible for the PC was GTA2, that's also the last time they made a game with the PC in mind, that was in 1999.
