Actually, the main problem is that the performances of the display lists compared to VBO are very different on all hardwares supporting both, it is not a popular belief. On ATI Radeon 9250 Pro, it depends on the size of the data set, when it becomes "big", compiled vertex arrays and static VBOs are faster, otherwise display lists are faster. On some other more recent graphics cards, I observed different results. VBOs were a kind of revamping of the whole API, display lists have been worsely implemented as time goes by except on some consumer and professionnal graphics cards whereas there is no such problem with vertex arrays and VBOs except on a very few OpenGL 1.5 compatible Intel chips.

Your slide only concerns NVIDIA.
