A Game Called Raptor

I have a DOS game called Raptor and I can get the game to run on my XP SP2, 700MGZ, 333M RAM. However when I select the game to use a SoundBlaser card, the game is sluggish. Without a sound card selected, the game seems to play fine, more or less, but better without a sound card active.
Any ideas what I can do on this system to play the game the way it should?
If I knew a good game board, I would post this there. So if you know one, let me know that too. Thanks.
Thanks.
