I haven't been able to play the game yet, most of the screen is green during segments.

I have a Toshiba P75-A7200 which has an Intel HD 4600 video type, with an old driver, it's been suggested that I update this to get the game working, but I can't figure it out. I've downloaded the latest Nvidia driver set, and I've tried to install this as a legacy driver, but I can't find the appropriate .inf file

Can someone please help? Thank you.

Nevermind, I figured it out. I was trying to use the actual Nvidia driver rather than the Intel 4600 driver from their website.
