Possible fix for nvldumd.dll crash
Spent hours trying to get this game to launch. Would consistently get the startup error message about nvldumd.dll after the pre-load screen.

Finally able to launch, I scoured quite a bit and hadn't seen this fix as an option. Go into your Nvidia Control Panel and then to Program Settings. Find the Sacred2.exe (Game Client) settings and I set the OpenGL renderer to my GTX 1060 as well as forced vsync OFF instead of Auto-decide I think. Along with the command parameters, the legacy PhysX drivers, compatibilty mode settings (these are are found all over the place on other links, if you found this you probably found them already) I'm finally able to launch into the Main Menu. Hope this helps someone at least
