Hey everyone, I am getting the following warning: 2010-09-16 14:40:16,335 (18296) WARNING: Unable to detect or automatically synch ronize buffer swapping with vertical retrace. May be possible by manually adjust ing video drivers. (Look for 'Enable Vertical Sync' or similar.) If buffer swapp ing is not synchronized, frame by frame control will not be possible. Because of this, you will probably get a warning about calculated frames per second differ ent than specified. This is a new one for me.. vertical sync used to work fine before. I am running Python 2.6 , PyOoenGL 3.0.1; I am getting the same warning on two computers and it down in fact look like it's not synching to the vertical refresh. Anyone have a solution?
