Retrobench
==========
A multi-platform framebuffer drawing performance benchmark targetted towards
retro PCs.

Retrobench intends to test how different operating systems, drawing methods,
and graphics hardware, affect drawing performance for a pure software rendering,
framebuffer access context.

Currently implemented benchmarks:

  - Fast XOR pattern scrolling: pure framebuffer write speed testing

Currently supported platforms/drawing methods:

  - UNIX X11 with the X shared memory extension (XShmPutImage).
  - GNU/Linux with framebuffer console (fbdev).
  - DOS direct framebuffer access through VESA BIOS Extensions (VBE).

Build on UNIX
-------------
Simply typing `make` should build both the X11 and fbdev version of the
benchmark. The only dependency is Xlib, for the X11 version.

Build on DOS
------------
Set up a DJGPP build environment and type `make -f Makefile.dj`.
