Don't know why not. This is a nice effect but I think this should default to off though in that this can cause quite a peformance hit on 'older' cards. On my geForce2 GTS the framerate hit varies between 10% and 100% depending on visibility range setting and what is in view and time of day i.e. starting up at default location at night brings my machine down to less then 10 fps which is quite a bit slower then what I consider 'flying' Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
