fbg

It looks very ineffective. For example, in fbg_draw() they have this code: https://github.com/grz0zrg/fbg/blob/master/src/fbgraphics.c#... > memcpy(fbg->buffer, fbg->disp_buffer, fbg->size); So they don't flip buffers, and don't even use video memory for them, they just copy data from buffer in main memory into a memory-mapped framebuffer. This must be slow. Also it doesn't check for vblank and therefore doesn't protect from tearing, but the description says they have "double buffering". As a side note, I remember that framebuffer was very slow on a computer I had. Without proprietary video card driver both Windows and Linux had troubles even scrolling a window, it was very laggy. Why was unaccelerated VGA (or VESA?) mode so slow, I wonder?
