I am on a Macbook and I just did Boot Camp and installed Vista onto my Macbook. I went through so much trouble to buy Orange Box to play TF2, only to find that it lags TERRIBLY. It's most likely the FPS because I'm fine when I'm standing alone, but during battles, I teleport around and cant do anything. I turned all my effects to the lowest on Video Advanced and also went on the smallest Resolution, but I'm still lagging. Is there anything I can do to fix it? Or did I just waste 30$?
