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!
