I am apalled at some of the negative reviews on this game. It combines spectacular graphics(It was built on the Unreal engine, so what else would you expect?) and a totally engrossing storyline. If you have a good top end graphics card that supports Direct 3d, then you are in for a spectacular journey in this game.  The direct 3D mode of this game is absolutely breathtaking  especially in certain levels. I have experienced no sluggishness at all with my Riva Tnt 2 Pro video card(a top end video card that is excellent).  However those who choose to use the low end cards like the entire Voodoo series(the yugos of computer video cards), will not enjoy this or any other game because of all the sluggishness those cards produce frequently.  I fully recommend this game to anyone who like me has waited for a a perfect blend of Role playing and fps games.  The playabilty of this game is wonderful and it is a fun, challenging game as well.  Enjoy!
