Hi Guys,
When using the TrackOverlay and drawing a single line, the bigger the screen the slower things go, when I reach 2560x1600 the line 'lags behind' the mouse by something close to a second, the smaller you go the faster it gets, 800x600 is acceptable. As an example, knock off the screen size limitation in the demo, bang it on a big monitor, go full screen and watch what happens.
Seems that there is an awful lot of calculation/refreshing going on behind the scenes. Is this not a ROP/rubber line thing, although GDI does not directly support this there are some seriously quick ways of emulating it.
Any thoughts?
John
