Why are OpenGL applications not accelerated? {{{ Ans: Do not intermix hardware acceleration and direct rendering. OpenGL applications will be hardware accelerated on Xgl if the driver supports pBuffers or FBOs, like the nvidia and fglrx drivers do. Direct rendering on the other hand is impossible to implement at the moment, the necessary extensions for implementing that feature are not even specified yet, let alone being implemented. Direct rendering implies hardware acceleration, but not the other way round. Direct rendering is a bit faster than indirect rendering, but indirect rendering is not as bad as it sounds. }}} Question2: [[BR]] How can I check whether I have direct rendering on Xorg? {{{ Ans: Direct rendering is active if running glxinfo|grep direct on top of Xorg (not Xgl!) shows you "Yes". On top of Xgl this will always show you "No". Unfortunately, for Xorg having direct rendering is a synonym for having accelerated graphics, and it is more difficult to detect whether hardware acceleration is available than it is to detect direct rendering. }}}
