The Performance and Quality tab for Geforce 4 Ti 4600

I have an odd problem, and was wondering if anyone could help. I have a Geforce 4 Ti 4600 graphics card and i want to turn off Vsync, but the only way to access the option is through the Performance and Quality drop down menu, but for my video card there is no drop down options for Performance and quality. I want to turn this off so i can get 100 fps while playing Counter-Strike, if any one could help that would be great, thank you.
