Game is Lagging!

[Midnightserenity]

Why does my game F.E.A.R. lag so bad on my windows 8 or 8.1? I'm so frustrated! It plays great for about 5 min and then lags really bad! So I have to end the game and restart, which gives me another 5 min of play. Only to have to repetitively play, stop, restart...play, stop, restart....Help please!
