Hi, My computer is a ThinkPad X31 with Pentium-M 1.4G CPU and ATI Radeon Mobility M6 LY. I manually tweaked the ports tree and installed FlightGear 0.9.8 on my FreeBSD 5.3-STABLE. Everything seemed to work except that the frame rate was only around 3 fps and the CPU usage was near 100%.
It seemed to me that FlightGear was not using hardware acceleration. My X-Window system is X.Org 6.8.1. According to glxinfo, the log file of X server, and the system dmesg, DRI and drm are successfully loaded and should be working. The frame rate for glxgears is 225 fps with rather low CPU usage. I suspected that I did something wrong when I manually tweaked the ports. However, a friend using FlightGears 0.9.6 from the ports with exactly the same hardware could also achieve only 3 fps. In order to see if this is a FreeBSD specific problem, I installed the 0.9.8 package for Windows. On Windows XP, I could achieve 27 fps; however, none of the 3D parts were showing. I could see the 3D models of the aircrafts when I choose the aircraft with the wizard. But in fgfs itself, I could not see anything 3D. I could not see any scenery out of the aircraft; nor could I see the 3D panel. I could only see the 2D panel; out of the aircraft, I could only see a blue scene in the day light and completely dark at night -- not even able to see the runway light. I tried to run an OpenGL test program on Windows. I passed the tests for OpenGL 1.1, 1.2, and 1.3, but failed the tests for 1.4, 1.5, and 2.0. Some other programs using OpenGL runs well. Is it possible that FlightGear uses some OpenGL features that my graphics card does not support that under FreeBSD software rendering has to be used and that under win32 the 3D objects could not be renderred? Any ideas? -- Leland Wang _______________________________________________ Flightgear-users mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d
