A few days ago I did a short experiment, benchmarking raw framebuffer drawing performance on some old computers, under DOS, and GNU/Linux with X11 (Xshm) and fbdev. My objective was to test how much overhead is imposed by the fastest X11 drawing method versus the performance attainable under DOS, and how much of that is due to X or Linux.
The most striking difference was on a pentium3 with a geforce2mx running the nouveau X driver, where I got 79.2 fps under DOS, and 23.1 fps under GNU/Linux with X11. Linux fbdev was somewhere in the middle with 41.3 fps. Here's the writeup in case you find it interesting: http://nuclear.mutantstargoat.com/blog/100-fbperf_experiments.html Source code for my simple benchmark is available on github, DOS version builds with DJGPP: https://github.com/jtsiomb/retrobench -- John Tsiombikas http://nuclear.mutantstargoat.com/ _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
