Reply To: Low Frame-rate?
VL-Bus was introduced in ’92, along with clock doubled 486 DX2 chips, so it would have been very new at the time and require a 486 or one of those rare 386 boards with VL support.
Hitting the 70fps frame cap would have been a big ask for anything but a top of the line DX2 machine of the time. Many games have logic based on framerate and start to exhibit strange behaviors when rendering too fast, so I generally recommend to keep dosbox cycles roughly in line with a high-end machine of whatever period a game is from.
