First off, I hope I am asking this question corrrectly.

X86 Based PC (Presario 700 series notebook).
Mobile AMD Athlon 1.4GHz
256 Meg sdRam
Video Card: S3 Twister K Compaq Graphics Card with 36meg Shared.
Sound Card: Sound Max Integrated Digital Audio
Operating System: Windows XP SP1
Game: Wing Commander II

I am having a problem playing Wing Commander II. The music, speech, and the overall frame rate lag. It is unplayable. I'm not sure what the problem is. I set the CPU rate to 7000 (which runs about 90% of my processor). Everything else seems to work other than the lag (sound, graphics, etc).

Sound mode used: Sound Blaster
Video mode: Default, there wasn't an option to change anything.
Version of emulator: DOSBox 0.61

I have tried different CPU rates and searched all over the net (I just can't find anything to help).
