HBAO+ In Ground Zeroes?

I recently bought Ground Zeroes on the PC (played it before on the PS3 so this is a pretty big step up) and was wondering if and how I can enable HBAO+ on it. I know that after a driver update HBAO+ can be enabled on TPP but I can't find a clear answer on how to enable it on Ground Zeroes. I've tried enabling "Quality" in the Nvidia control panel and enabling "High Quality" in the Nvidia Profile Inspector and they didn't seem to work. Any help would be appreciated, thanks.
