I am trying o run a game through dos box however its running SLOW!

What could the problem be?

keep pressing CTRL-F12 (might be F11) to up the CPU cycles. basically you need to emulate a faster pc.

Thank YOU!

Ive tried that And got till like +-600000 cpu cycles and well still lagging it took me about 10 minutes to get there..

Any other ideas or suggestions?

You can also adjust frame skipping. You can combine an adjustment of frame skips and CPU speed to create a fairly smooth running environment.

I'm not sure, but I think you adjust frame skips with ctrl-F5 and ctrl-F6. Might want to check that out.

Well i got it right it seems that dosbox doesnt like too much hard drive space?

I moved the simulated enviroment off of my 200 gig to my 40 gig drive and pop increased he cpu speed 60000 and voila.

However the sound is still scratching and not working.

perhaps the game isn't fully compatible with the version of dosbox you're using. check the compatibility list on the main site and/or try a different version.

DOSBOX is as well as a woman I found with a time. It can have looked at pleasant but it lacked the substance.

Would you mind telling us which game you're trying to run and how fast your CPU is? The hard disk space really shouldn't affect anything IMHO. Also, once you've found a number of cycles that works well for you, you can enter it in the <cpu> section of your dosbox.conf file (should be in your start menu DOSBox folder), to avoid having to increase it for several minutes everytime you start the program.

Sound lags because you have TOO MUCH cycles!
Normal rate of CPU cycles for DOS games is between 2000 and 8000. At 6000 and over, many games start to lag sound.
Try to find cycles where sound plays well, then add until it starts to lag. So you'll know how much is too much.

I'd try opening just dosbox in a window, not fullscreen. Then click ctrl+F12 repeatedly, say 22 times. Then open the path to the game and once it's running press alt-enter to make it fullscreen. Just because at least in my case the values returned to default as you close it. And it won't do anything if you have too many programs running at the same time.
I tried this game on these setups, and it wouldn't work because I had say, DC++, opera, IE, Firefox, BJ5, mIRC, Dreamweaver 8, Photoshop and winamp running at the same time, the usual, you know... Basically Dosbox needs a lot of CPU, and I should believe your game will work if you do as I did, closed most of the programs etc and got it working.

Try 10,000cycles.. Emulation takes alot of CPU power. So if you're emulating 60,000 cycles, your computer is actually running more like 600,000+
