Hi Ahir,

On my Dell & Nvidia dual boot (W7/linux) laptop there is the optimus feature which if it's on decides which graphics driver to use (on-board or Nvidia). You probably have a similar feature. In the system menu I switched the optimus off completely so I work only with the Nvidia driver. I did it mostly because of the linux side but keep this mode even when I'm under W7. My 2p advice.

Dear Chimera Users/Admins,
         I am having a sudden issue with Chimera, which refuses to
pick the Nvidia GT 540M gfx card as my primary card whenever I start
the program. 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!

The intel HD graphics card is not good enough for my needs.

Ahir

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.
