no issues prior to early release, now dx11 errors

I have the same issue. I literally cannot change the 144Hz refresh on my laptop (NVIDIA Control Panel lets me Adjust image settings with preview, Manage 3D settings, and Configure Surround, PhyX). Poking around everywhere I can think of, I only see 144Hz coming out from the drop down menus. Guess I'm hosed.

Same :/ no option except the 144Hz in all relevant dropdowns.
