[osg-users] Slow rendering with displaylist.

Hello, I am surprised about my little test program. I would like compare displaylists with frame buffer objects. Because, I suppose that the displaylists have to be faster than the vbo, because the displaylists are precompiled. But in my example I get another result: VBO: 225 FPS DL: 88 FPS

Hi Martin, That is basically true. I want to get a feeling about DisplayLists and VBOs. I know that the display list is a precompiled sequence of OpenGL commands. That is the reason that I tought the display lists should be faster. But the question isn't the comparison, but the slow render

Re: [osg-users] Slow rendering with displaylist.

Hi From my own experience, display lists runs with good speed when: 1) vertex number is at most like 100k, with huge vertices count per drawable vbos tends to be faster 2) display lists works best with triangle strips \ indexed list both display lists and vbos performance can greatly vary with
