I have an Nvidia Geforce 6600GT, 512 mb ram, 1.6 Ghz processor and when i play the game i put everything on max with no problems but it doesn't look like the Shader Model 3.0 is enabled and suggestions????
That is very correct. NBA Live 06 utilises SmartShader 2.0, which is a generation old, but still potent. I am pretty sure SmartShader 3.0 is used in DOOM3, and the newer first-person video games.
