TimeSplitters 2

TimeSplitters 2 returns with better graphics and bigger firepower, combining a dynamic storyline and stunning visuals with intense multiplayer kicks. In this second installment it is once again up to you to stop the evil Time Splitters from destroying the universe's space-time fabric. You'll travel through different historical eras, fighting in the roaring '20s, ancient Aztec temples, and outer-space robot factories. While the awesome multiplayer deathmatch mode is still here in all its glory, a more in-depth single-player and cooperative story mode, and a more advanced MapMaker feature, make for a more well rounded game experience. Up to 16-player action is available with four consoles and four links.

Problems
Why does my Timesplitters 2 lag so much on Dolphin...? Whenever I try to play Timesplitters 2 it lags so much that it ends up crashing. I don't know what to do... Do I need more RAM or something?
