I just reformatted my computer yesterday and got DosBox to run some of my old Dos games on floppy disk. However, for some reason all my games run extremely slowly on it and I can't figure out why.

Play with the cycles with CTRL-F12 (to get faster) and CTRL-F11 (to go slower).

If you just reinstalled DOSBox, the default cycle is 2000 or 3000. It might be too slow for some games.

Heh, you aren't running the games FROM the floppy discs are you? Oh :D , that was a bit of a joke.

Anyway, when you first open DOSBox, it says 'for more speed, try F-8 and F-12.

Heh, I just noticed all those other DosBox threads a few moments ago. I guess I should have posted there, but then again I'm an attention lady. :P

Anyway I increased the cycles and all the stuff you guys (and the folks in the other threads) suggested. Nothing. :(

Can you give us the spec of your machine and on which operating system you are trying to run DOSBox?

Win XP
1.4 GHz CPU, MSI K7T266 Pro2 mobo
512 MB DDRAM

When increasing cycles, make sure your CPU usage does not reach 100%, as it will slow down again.

What game are you trying to run?

For some reason, it ALWAYS goes up to 100%. So there is the problem.

I'm running the old JIll of the Jungle games and at first the resources are about 75-80% then it shoots up to 100% a few seconds later. I don't understand why it would do that, especially since I'm not running anything else.

What is your default cycle setting?

(when you start the game, check the of DOSBox window)

3000 cycles, no frameskip.

Well, I just installed my video driver for the first time (dunno why it took so long, but I thought it was worth a shot by downloading the driver update from nvidia.com) and the game performance has speeded up considerably.

You can install everest home edittion for free, and it will tell you how you can improve performance (check if you have all drivers etc.)

i have a problem with dos box i have a french keyboard and i cant change that beleive me i tried so i cant use the control button to speed up games......HELP

Your problem isn't this exactly but the twiddling around in control panel should work.

i tried that but my XP is not compatible thanks anyway

Got It. :Brain: :Brain:

Open a windows command prompt from Start Menu->Programs->Accessories

Use the CD\path command to move to your DOSBox folder.

type "dosbox.exe -startmapper"

This will open the DOSBox keymapper

select Mod1 underneath the picture of the numeric keypad

In the new section at the bottom of the window click Add

Then press the key you want to use instead of Ctrl.

You should now see EVENT: Mod1 BIND:(Whatever Key You Pressed) - If not click next until you have that - If it isn't there try again!

Click Save to store the change. Then when you run DOSBox that key should now replace Ctrl when you want to increase speeds etc.

This will only work with DOSBox 0.63 - The Latest Release

Hope that helps! :D

Sorted - should work now!

thx i am really impressed :kosta:
