What is the difference between Fastgraph/Light and Fastgraph?
The biggest difference is the TSR driver, called FGDRIVER.EXE, which must be loaded into memory before any programs linked with Fastgraph/Light may be run. Fastgraph/Light supports real mode only, while Fastgraph includes libraries for real mode, 16-bit protected mode, and 32-bit protected mode. Also, the light version does not include the world space and software character functions.
