Probably a Directdraw issue, it happens with several older games in Windows 7. You might want to check the other threads in this forum, and contact GOG support with a readout from Dxdiag if you're unable to find a fix.

Hello! I have the same problem as described in the topic. The game itself runs smooth and fine, but the screen just flickers non-stop and it's unbearable to keep on watching at it.

I've updated all my drivers but that did not help. What H2IWClassic said intrigues me for that is something I've never tried. I don't quite know what Dxdiag is or where to find a readout from it, but I really want to see if this dxdiag thing doesn't fix my problem :)

Thanks in advance!

Start->Run-> then type in dxdiag. Press enter to confirm.

This should bring up a window titled "Directx Diagnostic Tool". Use the "Save All Information" button to produce a text file, which you can then attach to an email when you contact GOG's support team.

Thanks for your reply but apparently I fixed it!

It was very simple, I just opened the config program for the game and switched resolution to 800x600... and now I can play perfectly!

Is it possible to play this game 1v1 with TCP/IP?
And can this forum be used to find players to play against?

A point I almost forgot and what fixed it for me. Crossfire, old games have the tendency to flicker if crossfire is enabled. Solved the problem for me.

How'd you open up the config program? I'm having trouble doing that with my game, and I have windows 7

Sorry for the late reply, I hope you see this.

It's a standalone program that should be installed alongside the actual game. You should find it in your KKnD folder, should be a red icon named Config.exe. Hope this helps.
