King's Bounty Dark Side Performance Sluggish on High End PC

[blueshrike]

Hi there,

Long time KB player and just purchased Dark Side from Steam. I have an nVidia GTX 860 on a higher end laptop and am getting very sluggish and choppy performance on whatever settings I seem to choose (natively 1980x1020), even if I lower the resolution.

Does anyone have any tips on what I might be doing wrong? Haven't had this issue for any other past KB games I've played even on much lower end graphics cards.

Thanks,
Tyson
