[Chimera-users] Graphics Driver not switching to Nvidia

Hi Ahir,

  Chimera does not decide which graphics card to use, your operating system decides that.  The Chimera graphics debug dialog comes up every time because you set the Chimera preference "Debug OpenGL on Startup" and saved that preference setting.  To turn that off use Chimera menu Favorites / Preferences…, turn the setting off and press the Save button at the bottom of the Preferences dialog.

I always get the Debug Graphics card, regardless of whether I have told the Nvidia Optimus technology to use the Nvidia card for chimera.exe. I am not entirely sure why this is happening, any help would be recommended!
