GDI benchmark

[Jim Davis]

Hello.

Here is a small benchmark tool to compare the GDI and Picturebox drawing methods and speeds. Also you can compare some GDI initialization and usage modes.

Any improvement in the mdraw.bas (that is a basic GDI frontend ATM) is welcome!

Also some tips to fix the flickering in direct gdi draw (vsync/vblank) would be nice!

hope you enjoy.

there we go, a big upgrade in gdibench11 ^^

added some nice features you may find useful (eg. text output, pen and brush pre-buffering), also found a way to fix the flickering in gdi direct drawing (it just happened ). it doesnt flickers on me, please report asap if you get any.

outstanding performance (+100% by comparing picturebox's methods) while drawing small amount of objects (less than 1000), by using the direct gdi mode (no blt'ing)
