It did that on floppy based systems too. The '87 equipped pcs in the physics building were much faster at 4500 line project, which I worked on for a year. So... First thing to test on a new 33Mhz 386 w/ wolf3d (install only, no source) my project loaded and 33mhz itt 387. Less than 2 seconds. If you brought everything into the ide,and hit run... It screamed.
