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. 26 Chapter 1

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.
