[Flightgear-devel] Main Airports Conflict with Graphic Card 6600GT !!!
I will tell you the most FGFS incredible history: I have discovered a conflict between main Airports and the Nvidia graphic card 6600GT. I cannot explain what and why. Does anybody can help me to understand ? With the last Nvidia driver (7664) that graphic card perform fgfs at a 70 fps speed and decrease to suddenly 2 fps. That low performance appears when we look toward a MAIN Airport or if the Aircraft is on a such Airport (it does not happen near a secondary Airport) -ie: KSFO runway 28 ,running for take off == first 2 fps during about 100 meters and == suddenly 60 fps continuously In order to prove it i deleted some suspects Airports from the scenery directory SOME.btg.gz taking off from a little airport. The result was good: the aircraft can fly with a very valuable fps over and toward the same places without difficulties (more than 60 fps). What differences between a main Airport and a little one could explain that very curious effect ? ( Equipments: NAV ?, RADIO ?, LIGHT?,...) I have tested, after deleting airports objects (tower, beacon, windsock,..) and after deleting textures, no change. Theses are not the explanation, what else ? Before coming back to my dusty 5200.

Probably the runway and approach lighting.

One solution, as pointed out by Melchior is to go back to 6629 drivers. If you're running 2.6.11 kernel you will have to patch them as per the instructions at: http://www.nvnews.net/vbulletin/showthread.php?t=46676 Though I didn't try the other solution suggested to turn off enhanced runway lighting, which would certainly be easier. The 6629 drivers also give better performance with the torcs driving sim so I'll stick with them for now.

Geoff You are all right it is coming from the runway ligh, unfortunately no change when acting on theses properties. It seem coming, only, from the red lights which are on the left side at the beginning of the runway, when running on, as soon as passed the lights the fps is good. Can i deactivate theses lights, to test it ? About 6629 with patch I have been working with it, it could be ok but on my side the fps is not better than my old overclocked 5200. And 6629 + 6600 GT does not give good performances with Celestia (an other Star history) -- Gerard -- Gerard ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
