I still can't find a way to make it work with 24bpp modes. That would open up the benchmark to older systems with cards that don't support 32bpp (ie. many ISA/VLB cards) I've never worked with vbe before so I'm really going blind in here. Any help would be appreciated :) Actually the current …

Sorry to hear that. At least you can use my working copy of the benchmark for testing old machines. 😀 I'm going to include it in all my future comparisons and if somebody else also wants to adopt it as a benchmark for their retro adventures... I'm happy to have given my little contribution.

A bit of warning, I wasn't able to compile it using Open Watcom. It gave me many errors and missing dependencies. For some reason, using WCC 11 instead, everything went smooth without any change at all. One would think that Open Watcom would be 100% backward compatible and using the same libraries …

You're welcome. Let me know if it works for you, and -if you can- test it on some old hardware. I'm not really good with C++, plus I haven't touched it in more than 20 years. I wish I could really add a nicer interface or tweak it so it can use more video modes, but it's something beyond my current …

It seems POVray DOS is just a command line utility with a text based log. It creates a .tga file with the output rendering. C-Ray was created in 2005, when DOS was already dead. At any rate it's code is compact and straightforward enough that can be ported to anything. The original author even …

For dos raytracing bench, I exactly mean a program that renders an image using raytracing techniques. C-Ray does that (and now I've been able to compile and modify it to display a stopwatch), Povray does that too (and much more!), although it's not as "interactive" as C-Ray, where you can see the …

If oldschool ray casting 3D (2.5D) game engines qualify for "pure DOS software ray tracing benchmarks", you may try WOLF_286.EXE (Wolf3D for 80286 CPUs) with FPS counter. Mind that it needs data files from paid full game. I already use wolf286 and doom for benchmarking old systems but I think those …

Pure DOS ray/path tracer, for those generally interested. Stresses FPU. Tested in DOSBox, 80 x 25 mode only. Optional CLI argument sets sample count, default 40. Thanks. If you had to draw the same scene as c-ray (see pic above) using path tracing, at the same resolution, how much more computing …

It should be fine to use the standard C time() function to measure this benchmark, provided the render takes time on the order of seconds or more. time() should have a resolution of the system's clock (32Khz was it?).. which is fine enough for comparing lengthy renders. Thanks. I came to the same …

A quick update... it turns out the source code is not compatible with Open Watcom C++ Since it was made in 2005, back then the most recent Watcom C++ environment was release 11 of 1997. So I've tried compiling it with the older compiler and... it worked! :D Now it draws a raytraced scene... Nice! …

C-Ray is going to be an FPU benchmark. The 32-bit version is supposed to be compiled with Watcom, so I'm guessing OpenWatcom can be used to cross compile. The entire code is just 4 source files. You don't need a make file if it's not working for you. Just invoke the compiler on each file to get an …
