@Stabiz/wetwave,
Perhaps the nivida card, you both have the same:hmm: manufacturer. I don't know. The game is smoother for me with PPF on. I shoved in a Radeon X1300 512mb yesterday and it works just swell. I start to slow when in outside view, shallow water with all the rocks and stuff looking at the sub from the outside. The blurry water is cool. Not much of hit on FPS to want to turn it off though.
