Hrmph. If I run FGFS as the only app, without window manager, everything else in the system stopped except the X server itself, with both the server and the app running as root (so that this non-DRI system can avoid context switches), I gain less than 10% framerate compared to having a fully-up posix environment with all the bell-and-whistle services running in the background, a window manager, various other windows providing diagnostics about the running simulation, and similar. I can burn 10% framerate trivially by switching between the instrument panel choices, or looking at two runways at the same time. If you're using a kernel with inferior context switching, or a GUI that integrates the window manager, desktop manager, display manager and widget kit all into one huge system interface, then I pity you ... 8-) _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
