Hi, do other programs with OpenGL rendering work? Can you use the wglinfo program: http://www.cg.tuwien.ac.at/~wimmer/wglinfo/ It outputs the information of the rendering system. The problem seams to be that OpenFlipper is unable to get the OpenGL context. Regards, Jan Möbius On 24.12.2010 07:40, yaoyansi wrote:

hi, I'm sorry for a mistake in the previous email, that is I use OpenFlipper1.0RC7 not OpenFlipper1.0.

When I launch OpenFlipper.exe, it complains: Warning! The OpenGL capabilities of your current machine/driver are not suffient! The following checks failed: OpenGL version less then 2.0! Please update your driver or graphics card.

When I press "OK", it pop out a crash windows which says "Stereo Setting:OpenFlipper.exe".

My evironment is windowsXP, Winfast GTX460(NVidia), and I have already upate the driver from nvidia official set.

Is this a bug? or could you tell me how to deal with this problem?

Regards yaoyansi
