DX11 option not available in launcher

The dx11 option in the config section of the launcher is not available for me to click. I have re-installed the client 3 times, tried changing the FFXIV_BOOT.cfg file to force dx11, disabled and re-enabled SLI, modified anti-virus settings, and verified dx11 install. None of it worked. GTX 970, 64-bit Windows 7. I ran the dx11 HW benchmark and scored 16362 on 1920x1080 maximum settings. No idea what else to try.

Figured it out. Any setting that modifies user agent header information is probably going to disable the option in the launcher. Which means any "stealth web browsing" setting probably fits into that category
