[Flightgear-devel] Speed problems under Solaris

2005-10-24 Thread Martin Rosenau
Hello. Someone said that it is no problem to run FlightGear even on an Ultra-5 machine. I run FlightGear on a Blade 1000 with an 750 MHz UltraSparc processor (this is equal to a Pentium machine with 2,3 or 3 GHz speed). The screen refreshes every 8 seconds. Any keyboard input requires 8

I'd expect that you need something in the XVR-1000 range and I don't know if that fits into an Ultra5. Hello. I think it is not only a problem of graphics. Even the network stuff (e.g. props at TCP port 5501) has 8 seconds delay. This should be capable of carrying a graphics board that

Hello. I found out that for each simulation step an usleep(93 ms) is done. The screen is updated only every 64 simulation steps. 93 ms X 64 = ~7 seconds I have no idea why the display is only updated ONLY every 64th simulation step. Textures are not the problem; I can use --disable-textures
