Re : Re: Re : Re: [Flightgear-devel] getting the best perfo with FG
I forced 60 Hz because I will use a projection system ;) Well for the moment, I don't think I need to lower my fps, but maybe, what would be nice is if I could force FG to run at a given fps which prevents me from little freezes... ;) David --- Message d'origine --- De : Harald JOHNSEN [EMAIL PROTECTED] : FlightGear developers discussions flightgear-devel@flightgear.org Sujet : Re: Re : Re: [Flightgear-devel] getting the best perfo with FG Date : ven 17 jun 2005 10:45:48 CEST BONNEVILLE David wrote: From the Quadro FX 3000 : * 60 Hz refresh * vertical synchro forced * no AntiAlias * no Anisotropic filtering * 1280*1024 * 32 bpp * visibility 5 meters --- Message d'origine --- De : Ampere K.

Thanks David Well, 30 fps isn't that bad in my opinion, considering I only have 15 fps if I am lucky. What other options did you use beside vertical synchronization?

There is something weird somewhere in the code, don't know if someone has allready investigated that or perhaps it is simply by design but those freeze are a real pain. The fps can drop by 50 or 90% for a few frames for no reason. Is it caused by the 360 scan done every 500 frames, or some side effect of the autogen or perhaps some other piece of code (atc, ai, fdm, etc) ?

You can only effectively reduce them by using a dual processor system and with threads enabled. Reading the scenery from disk does take time, whether you like it or not. Using SCSI (and disk striping) would help also.
