Okay, either someone messed up the requirements for the old (MS-DOS) Apogee games, or they're being run on a terribly inefficient emulator, way more inefficient than DosBox.
Apparently,
Alien Carnage,
Arctic Adventures,
Math Rescue, and effectively all MS-DOS Apogee games now require an
Intel Core 2 Duo or higher, and at least 2 GB of RAM!
WHAAAT?!?!?!?!
