Hi Gert, ATI dont' do display lists efficiently so you could try disabling the use of display lists.
The env var OSG_DATABASE_PAGER_DRAWABLE can be used to switch off the use of display lists in the pager by setting it to VertexArrays. osgviewer --help-env Will display the available env vars. You can also set this option programatically via the DatabasePager interface itself. Robert. On 1/31/07, Gert van Maren <[EMAIL PROTECTED]> wrote:
Hi guys, I know this has been discussed extensively on the list and brought to attention of ATI. ATI have improved their drivers however I don't think they fixed it completely. I have a 25Gb globe and paging on a machine with a ATI X1600 card is still considerably slower than on a machine with a GeForce 6800. Machine are identical in RAM and have same HDs. Framerate on ATI drops to 10-15 while paging, eventually back to 60fps when every tile is paged in -> frame rate on Nvidia is 50-60 fps while paging. Of course Vsync is always on on both machines. Any other tips on how we can improve the paging on ATI cards?
