overview of OpenGL
environment variables
Additionally, an application can programmatically switch between the slower and faster double buffering methods using the following new glHint calls:
glHint(GL_BUFFER_SWAP_MODE_HINT_HP, GL_FASTEST);
Switches to the faster double buffering method.
glHint(GL_BUFFER_SWAP_MODE_HINT_HP, GL_NICEST);
Switches to the slower double buffering method.
Note that setting either
HPOGL_DSM_ENABLE_FAST_BUFFER_SWAP or
HPOGL_DSM_DISABLE_FAST_BUFFER_SWAP in the application environment will disable and thus override the behavior of the new glHint calls.
