Hi. I solved the problem myself a while back. what i did: I turned the graphic driver for Dune Legacy to integrated graphics, instead of my Nvidia video card. worked perfectly, hope it helps you too! Good luck
I've seen some more threats about this, but since i installed version 0.96.4, my screen starts flickering ingame, not in the menu's. i cannot find anything on the forum that can help me with it. can somebody help me?
