Configuration:CPU

The CPU section controls how DOSBox tries to emulate the CPU, how fast the emulation should be, and to adjust it. DOSBox offers 4 different methods of CPU emulation.

core = simple | normal| full | dynamic | auto

CPU core used in emulation. auto switches to dynamic if appropriate.

Default is auto.

Setting dynamic gave a significant performance boost in Wolfenstein 3D.

cputype = auto | 386 | 386_slow | 486_slow | pentium_slow | 386_prefetch

CPU Type used in emulation. auto is the fastest choice.

(since 0.73)

Default is auto.

cycles = nnnn | max | auto

Amount of instructions DOSBox tries to emulate each millisecond. Set to max to automatically run as many cycles as possible. auto setting switches to max if appropriate.

OBS: Setting this higher than your machine can handle is bad!

Default is auto.

cycleup = nnn

Amount of cycles to increase with keycombo.

Default is 500. Setting it lower than 100 will be a percentage.

cycledown = nnn

Amount of cycles to decrease with keycombo.

Default is 20. Setting it lower than 100 will be a percentage.
