Bootcamped Mac need help with updating of drivers!

[Obtuse]

Guys, i recently bootcamped my Mac with windows and downloaded Dota2, at first it was working smoothly but now my laptop is plagued with lags and will have error when joining games thus, during pre-game i will lag out. Apparently i need to update my drivers, what drivers do i need and how do i update them?

This is depending the Mac you own. You can open the Device Manager in windows and check which card is under Display adapters. As well you can check on the System Profiler in Mac under Video section.
After you determine your card, you can go directly to the sites of Intel, Nvidia or ATI
