PATH_BENCH is a simple path tracing benchmark for DOS. Renders a basic scene and outputs the time it took to do so. Requires a math copro and can be quite slow on pre-pentiums.
What's path tracing? Like ray tracing, but better and more computationally demanding. Heavy on floating-point math. Look it up on the wiki.
Results, in order of render speed:

Timing should be correct on real hardware, but not guaranteed in e.g. dosbox (check your settings). Designed for square pixels (16:10 ratio).
