Sry if wrong section: when i start to play sonic adventure 2 the controls don't work except for cvb (which i guess are something,b,a on the controller) and as well how do we make it run more smoothly? Mine runs decently than sometimes the words become choppy or are said 2-3 times and the animation slows down and my FPS gets a drop down. Occasionally itll just bounce up and down lol, LMK thanks /e: The specs of my system: Vista 64-bit ATI Radeon 3200 HD 4 Gigs ram AMD turion x2 64 Dual core processor 2.20 GHz
