The CPU section controls how DOSBox tries to emulate the CPU, how fast the emulation should be, and to adjust it. DOSBox offers 4 differents methods of ((/cpu/core/Intro|CPU emulation)).
core = simple | normal| full | dynamic | auto
CPU core used in emulation. auto switches to dynamic if appropriate.
Default is auto.
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.
