--- Comment #10 from Thomas Spear Speeddymon@gmail.com 2010-09-09 14:57:10 CDT --- Also, since the crash is happening on the login screen, in windows, add the -console argument to the wow command line, and on the login screen, press the ~ key to bring up the console.
Then type 'cvarlist' to see the complete list of CVars, and look for the gxApi line, I wonder if the login screen uses dx11 and maybe that is why its crashing there?
