2013 rMBP bootcamp issues

Hello. I have a late 2013 rMPB that i have windows on. I use windows 7 with bootcamp and i can also boot my windows 7 partition using parallels. The problem is, Bootcamp installs relatively older drivers for everything. I have NVidias 327.16 driver installed currently that bootcamp installed. I am having issues playing the game that i want to play with this old driver. I have Nvidia GeForce experience software installed and when i check for updates it says i am up to date. However, when i check manually I find that there is a 332.21 and 334.67 beta driver. I tried installing one of these(i can't remember which) and when i opened the game the screen strobe flashed between a black screen and the game menu. Should I backup my windows 7 and retry or is there a special way to update the driver? I have the NVIDIA GeForce GT 750M 2048 MB graphics card. Thanks

I can't find a strait answer on how to do it
