FireGL Linux Driver Port (correction, clarification) X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 27 Dec 2005 09:28:26 -0000 glxgears is not a benchmark! In any case, there could be a lot of reasons for the slower glxgears performance with the fglrx driver. However, like I said before, the fglrx driver as of now has zero 3D acceleration, so slow GL performance is to be expected. Also in regards to fgl_glxgears not running, that is because it uses ATI pbuffers, and the FreeBSD libGL builds we have do not currently support these. When/if ATI makes custom FreeBSD libGL builds that include these, fgl_glxgears it will work the same as it's linux build. Also, I am about to release a new minor revision of the drivers with some fixed make rules and a preliminary FreeBSD port. (Port as in ports system) Should have it up within the hour for everyone to test.
