33## Introduction
44
55GraphicTest is simple program which measure FPS of various direct drawing methods. Aim is to determine fastest method how to copy custom off screen bitmap to visible area on screen.
66
77Listed benchmarks results are dependent on:
88
99- computer hardware
1010- compiler optimizations
1111- operating system
1212- used GUI toolkit
1313- vertical sync and max FPS limit
1414- display color depth (default 32-bit)
1515- resolution of image (default 320x240)
1616
1717In some methods it is necessary to do swapping B a R component of color in some platforms which results to better/worst test score.
