I have recently changed my computer and I'm now under Windows 7. Before, I run under XP and all my OpenTK projects looks good.
Today, I just restart one project and I have a strange artefact. Now we can see a small gap between polygons in the linked image.
I have the same problems with all my old projects !
Does someone have an idea ?
I have all my drivers installed for my graphic card (nvidia). Could it be a settings in the cg manager software ?
