When I move the mouse it puts lines on the screen, on the set up screen the lines are permanent however during game play the lines do disappear after a few moments.

All of my drivers are updated, I am running as an admin, in WinXP SP2, I turned off UAC.

I am running Win 7, my graphic card is a GTX 465.

Thanks in advance.

EDIT: I also clicked every box in the Compatibility tab and ran the game with every mode, still getting the lines.

I use a similar setup except I have a Geforce 7950GT. What version of the Nvidia drivers are you using?

258.96

Have you tried running XP in a virtual machine and then installing H3?

No I haven't tried that...... time to go look up how to do that.

I Also have same issue. My Graphic card is GTX460. and it makes me buggy. this is the first time that I purchase GOG game. and I am a bit disappointed.

I think if GOG does not solve this soon, I need to ask refund...

Anyway, I will send mail to GOG of this issue.Well..

I've finially solved this after apply HOMM3 HD.. it is much better.^^
