Lucky, I just searched for the newest released driver that is not beta. Mine that is working without the lines on the map is 337.88. I did not install any bloatware. The only thing I installed was the driver and physX, no sound drivers or the Nvdidia experience. In star wars the Old republic the Nvidia experience was causing issues so I Opted to not have it installed.
Make sure you go to advanced installation and check 'clean install' so it wipes out un-needed driver bits.
