What is slow with ATI cards? Â It seems that you should only need basic 3D acceleration to do what you propose. Â Is fglrx missing something that would be required for 2D rendering? Texture upload is very slow. glReadPixels, glWritePixels and friends take ages. That means that blt, Lock, and Unlock is really slow. There is some hope at least: Xine and Mplayer can play videos over OpenGL really fast, maybe we can find out how they do it.

Indeed glReadPixels and glWritePixels might be slow using the Ati drivers but those calls weren't used for the texture uploading. For that purpose just glTexImage2D / glTexSubImage2D calls were used. If texture uploading was slow on the Ati drivers people would be unable to play games ;) Roderick -- GMX DSL-Flatrate 1 Jahr kostenlos* + WLAN-Router ab 0,- Euro* Bis 31.12.2005 einsteigen!
