Whenever I try to run my old DOS games from a CD I always get stuttering sounds once and again. It's not that mad, but slightly annoying. I'm running at around 7000 cycles and I've changed output to overlay, but still the same. I've created an ISO from the CD and have mounted it using Daemon tools to speed up access time.

My specs:
*Laptop*
Pentium M 1400 MHz
768 Mb DDRAM
290 Gb HD
Nvidia Geforce 64Mb

Is there anything I can do? I've looked at the "known problems" thread...

It's not that big a deal, I'm just wondering what I can do to fix it. It's not stuttering that much.

change display depth to 16 bit.

I can't find that option in my dosbox.conf...

[Qbix]

for your operating system.
dosbox doesn't like 24 bit and sometimes it seems that 32 bit messes up as well.

A stuttering sound happends when dosbox looses it's internal timing. This can happen because of 2 things. CPU emulation takes too much time (cycles to high)
or the drawing of the screen takes too much time. (this depends on a lot of things but is very depended on you display depth)

How do I change it to 16 bit depth?

[Qbix]

what is your operating system ?

[MdaG]

XP

Changing the CPU core to dynamic doesn't help (not that I've noticed anyways).

Display depth is in the Display Properties dialogue (Right click on the desktop, Properties, Settings and select 16 bit in the drop-down box. The appearance of that panel depends on your display adapter, but it'll be on there somewhere).

Oh ok, thanks. I thought I was suppose to use some display property of DOSBox'.

[Qbix]

Please tell if it worked.

if it doesn't you can increase the prebuffer a bit.
or change the scaler to none

[MdaG]

Nope, changing the OS depth to 16 bit instead of 32 bit didn't help...
I had the exact same problem on my Gentoo system.
