Ok, this is quite strange in my opinion. My computer is a Windows XP Desktop with 512 ram, 2.8 Ghz Intel Celeron Processor, with a Nvidia GeForce 4 MX 4000, 16x disc drive, and Direct X 9.0c. It's a year and a half old and I take good care of it.
Here's my question my game doesn't allow me to turn on the "Lighting" feature, which I have been told improves the games graphics in terms of sharpness a wee bit. My current problems are: overall sharpness and definition of courts and players

on Maximum detail setting. And on the backs of jerseys and on the floor there are little white boxes that after countless adjusting of still wont go away

. Could anyone please help me with this problem and/or make some other suggestions on the improvement of overall graphics?
