Thanks for your reply.
I forgot to mention that I used VDMSound with GP2 almost for three years and when I had a single core processor, it was running very well. Now when I've moved to a dual core one, GP2 is more stable and runs better on DOSBox, except sounds. (Even VDMSound didn't provide best possible quality with a dual core processor.)
I don't need GP2Lap, so it's not a big issue.
EDIT:
I was browsing other forums and found that the following settings were suggested for the most of the games:
blocksize = 64
prebuffer = 1000
With those settings GP2's sounds are almost sync, well enough even.
GP2Lap? - It works brilliantly with newest version of DOSBox. At least if GP2 and GP2Lap are installed normally to the HDD and then created a shortcut for GP2Lap running on DOSBox.
