I'm running FlightGear on an SGI Octane MXI (supplied with the recommended texture cache RAM, so called TRAM). Besides, this machine employs a cross bar switch to connect CPU, RAM and display (which provides a theoretical bandwidth of 1.6 GByte/sec) and has two parallel rendering pipelines/engines so I expect this machine to be 'pretty fast' (TM) at rendering a whole scene. This can be demonstrated with several demos (SGI and 3rd party). Unfortunately this machine is still quite slow at FlightGear (even without using textures) - I believe this is caused by the slow CPU (195 MHz only). So if you say that the FDM only takes a few cycles the conclusion would be, that processing the scene graph takes most of the time, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
