I've also been confused by the monumental frame drop that even the simple runway lighting can produce at airports such as EGLL. And I do have a fairly hefty system which has been known to run graphical behemoths like Doom3 at a fair lick. The obvious response from the 'non-programmers' perspective ie: 'user' is: "Why on earth do these little dots bring my new Model-X video card to its knees?" So what's the crack? ;) Dave Martin _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
