Witam serdecznie!
Mam problem z OpenGL-em. Otóż zauważyłem, że wiele aplikacji wykorzystujących OpenGL-a do działania potrzebuje następującego rozszerzenia “gl_ext_framebuffer_object”. Niestety w moim systemie to rozszerzenie nie wiem czemu, ale nie jest dostępne.

Karta graficzne, której używam to ATI X1400. Mogę jeszcze dodać, że próbowałem obu Open Source-owych sterowników, czyli Radeon i Radeon HD, lecz na obu sterownikach to rozszerzenie nie jest dostępne. Szukałem w Internecie jakiś informacji, niestety bez rezultatu i dlatego tutaj gorąco proszę o pomoc.
Co zrobić, aby rozszerzenie “gl_ext_framebuffer_object” było dostępne?
Z góry bardzo mocno dziękuję za pomoc.
Pozdrawiam,
Fryderyk
