Hi Guys,

However it has to be said ( or written ), that Marco's tests are not very representative. You can't put everything in one drawing path - a path is AFAIK defined for one pen size / color.

There are many other choices too - just read my posting about the different graphics backends.

Cairo can be used directly - I'd assume that's much easier than trying GDI+ on windows - the GTK group maintains the port for Windows / MINGW. http://www.gtk.org/download-windows.html

wxGraphicsContext is basically a abstraction layer for Cairo - most functions are very similar - however Cairo supports even much more functions.

Another variant is the use of OpenGL and its hardware acceleration.

I'm writing currently a better benchmark for wxGC and OpenGL - first tests on my notebook show that OpenGL draws lines at least 30x faster than wxGC. I'll try also Cairo with wxWidgets.

I had problems with boost::timer - the value seems to be incorrect (?) 

Bye ..
Torsten
