MP games are in because AI has been incompetent and a dullard.
AI Must elvolve if games are to mature and a new generation of games to evolve.
1080P 60fps with good lighting and filtering is more than enough. The focus o. Real life isuals doesn't mean Squat when a tank gets stuck on a bush or when you snipe an enemy and another Ai right next to him does not even notice.
I could go on but we have all been there dealing with dumb AI, and physics that just does nothing.
