Fundamental Theory of Poker - what if? LC

[Master5hake]

what if it was possible for a hacker to be able to see all of his opponents hole cards at the start of each hand, but wasn't able to accurately determine the future community cards - (outside the narrowing of odds based on all the cards he could already see in people's hands)

what expected win rate in bb/100 would he be able to expect given he had at least an basic understanding of poker theory? - lets say he played a mid limit (10/20) full table game -

also - if he could see all of his oppenents hole cards, where would his ideal VPIP fall? I would imagine it would be high, possibly folding when he had a very poor hand and he saw two players at the table had hands they would raise with - making 3 bets before the flop even too expensive for him -
maybe I am off base thinking that an ideal VPIP in this situation would be so high

any thoughts?
