Poor performance when drawing high density trackpoints in map
I am using BT474 to capture trackpoints every 5 meters. This configuration generates files with more than 50000 trackpoints that BT474 can draw in the map but with an extremely poor performance.
I suppose that the program tries to draw every point at any given scale but for some scales there is no reason to draw trackpoints since the resolution of the screen is unable to distinguish them.

Hi BT747 does evaluate every
Hi
BT747 does evaluate every point on every draw, but does not actually draw every point.
The process could be optimized further of course, but I found speed to be acceptable in my trials.
A good alternative is to export to 'HTML' and check your tracks in a browser.
Otherwise, the algorithm to draw the tracks needs some changes.
