Alright, Fallout was not starting on my Windows Vista, so I just said to hell with it, and went and bought ANOTHER COPY and installed it. After 2 hours, the game launched and was ready to play. I instantly noticed that the mouse Jumps from spot to spot. Then, I started a new game, and when I looked at the doc, it was so laggy. Lag, and mouse jumping, not bad not bad.. So then, I notice that either my graphics are set low somehow, or the graphics are way worse than fallout 3. I've watched countless videos and fallout nv looked awesome, but on my pc, its horrible. Someone, please help. Lag, Graphics, and mouse jumping. And yet, I still want to mod the game after I beat it, but I cant get passed the bottles because my mouse jumps when I try to aim. Someone, help please.
