Different applications, even their parts, may have different this dependency.There are two components for playing a psx The Need for Speed rom on your PC. Rough dependency between cycles and emulated CPU. Note: Based on Speed Test 1.14 and other. An application's and the emulator's settings affect too, - for example, sound's settings. Different applications, even their parts, may have different this dependency. For core=dynamic (cycles=max), while core=normal may to be 5 times slower. It's rough speed level of emulated CPU for different host CPUs. This will use cycles=5000 for real mode games, 80% CPU throttling for protected mode games along with a hard cycle limit of 20000 The cycles=auto and cycles=max settings can be parameterized to have different startup defaults. Setting nosound=true in DOSBox's configuration does NOT disable the emulation of sound devices, just the output of sound will be disabled.ДЄlso try to close every program but DOSBox to reserve as much resources as possible for DOSBox. You can also try to disable the sound through the setup utility of the game to reduce load on your CPU further. Please note that this is a trade-off: you lose in fluidity of video what you gain in speed. You can repeat this until the game runs fast enough for you. Your CPU usage should decrease when using a fixed cycle setting, and you will be able to increase cycles with CTRL-F12. Increase the number of frames skipped (in increments of one) by pressing CTRL-F8. VGA emulation is a demanding part of DOSBox in terms of actual CPU usage.

Note that there might be games that work worse/crash with the dynamic core (so save your game often), or do not work at all! But you may also try using it with high amounts of cycles (for example 20000 or more). This usually gives better results if the auto detection (core=auto) fails. On x86 architectures you can try to force the usage of a dynamically recompiling core (set core=dynamic in the DOSBox configuration file). In this mode you can reduce the amount of your real CPU's core usage by CTRL-F11 or raise it with CTRL-F12.

This time you won't have to care how much free time your real CPU's cores have, because DOSBox will always use 100% of your real CPU's one core. The DOSBox window will display a line 'Cpu Speed: max 100% cycles' at the top then. You can also force the fast behavior by setting cycles=max in the DOSBox configuration file. DOSBox can use only one core of your CPU, so If you have for example a CPU with 4 cores, DOSBox will not be able to use the power of three other cores. Once 100% of the power of your computer's real CPU's one core is used, there is no further way to speed up DOSBox (it will actually start to slow down), unless you reduce the load generated by the non-CPU parts of DOSBox.

You can see how much free time your real CPU's cores have by looking at the Task Manager in Windows 2000/XP/Vista/7 and the System Monitor in Windows 95/98/ME.

In this mode you can reduce the amount of cycles even more by hitting CTRL-F11 (you can go as low as you want) or raise it by hitting CTRL-F12 as much as you want, but you will be limited by the power of one core of your computer's CPU. If you for example set cycles=10000, then DOSBox window will display a line 'Cpu Speed: fixed 10000 cycles' at the top. You can force the slow or fast behavior by setting a fixed amount of cycles in the DOSBox's configuration file.

But you can always manually force a different setting in the DOSBox's configuration file.

How to speed up/slow down DOSBox CPU Cycles (speed up/slow down)Д«y default (cycles=auto) DOSBox tries to detect whether a game needs to be run with as many instructions emulated per time interval as possible (cycles=max, sometimes this results in game working too fast or unstable), or whether to use fixed amount of cycles (cycles=3000, sometimes this results in game working too slow or too fast).
