The flickering for me made the game virtually unplayable (I suffer migraines) - using nvidia inspector to force the framerate to 30 seems to have fixed the flickering for me too! Woohoo! I can play the game now :)
tried it on the gruntmods edition (labelled as 1.07?) on atredies mission 1, patcher said invalid checksum on the .dat file but the game seems to run fine @ 1024 x 768. did atredies mission 1 with no problems. going to try a skirmish now. also I have 1 quick Q (sorry this isn't tech support forum) but even with vanilla Dune 2000 on Win7 I get the screen flicker all the time :( I did a check but found no fix, anyone know?
