Hello!
First I want to say, that I am from Germany and that my English is very bad. I hope you can understand it.

I have a problem with Dosbox on my System:
AMD Athlon XP2000+
512 PC2100 Cl2 Kingston
MSI K7N2 Delta-L Nforce2 SPP
Sapphire Radeon 9600 pro 128 MB
Windows XP + Sp1 + all important Updates
no programms are working in the background, when I'm running Dosbox

The problem ist that the game I want to Play, called "Formel 1 Manager 96" (but I think it is Dosbox in General) works very slowly. He is reading from the HDD every second and the loading-time in the game is very long. For Exampe, in my old 486 DX 66 Mhz it was able to load the screen in 1 second, with Doxbox it needs almost 10 seconds and the game is nearly unplayable slow. Are there some special options in Dosbox like for the Ressource-Management, which can solve the problem?

I hope you will be able to help me and I they already "thanks a lot"

Greatz to all

ok, first, it's a CD Rom game or a disk game ?

If it's a CD Rom game, try to make it in "image" with Nero and use a virtual CD Rom driver like : Daemon Tools (free soft) after that, it's will imporve the time access ...

Now, if the game in directly on DD, just try to increase the CPU Cycle with :
CRTL+F11 -> Reduce
CTRL+F15 -> Increase

You can use : Frame Skip too :

CRTL+F7 -> Reduce
CTRL+F8 -> Increase

Tell me if it's better ?

Sorry for my poor english ! 😉 But, try to speak french like I'm speak english ! 😀 It's not easy !

Ahhh Thank you! Now it is running nearly normal!!!! Thaaaannnnls!
But it is strange that he is reading from harddisk every second, is that normal? (It is a CD-Game).

Greatz

it's ctrl-f12 instead of ctrl-f15

and reading every second from hd is not uncommon.

O.k. Thank you!
Will this change? I mean will the Emulator in later Versions be able to use RAM instead of everything reading from harddisk?

dosbox uses only ram. It's probably the game doing it.
if dosbox is doing it. then you probably have spyware or a virus on your pc. 😀
