For anyone interested,
I had problems with AoD on WIN10, Nvidea and the STEAM version. The game would not start - the AoD process was just idling at task-manager view and no start-screen showed up or sometimes just a black screen. After I tried dozens of things I saw somewhere a hint to the Nahimic-driver, which is a sound-manager which comes with MSI-motherboards. So I just had to close this program and the game runs flawless now. So before you do the major stuff maybe just try to diable all the drivers atarting automatically which are in autostart.
I have one questions as well: I play with modded sprites and previously under WIN7 it was no problem to play with 10Gigs of sprites in the game. Under Windows 10 I get a crash on start screen with too many sprites somewhere in the Area of 1-2Gigs. Now I have 1.2Gigs of sprites enabled and it is running without problems. I just wonder because I had under Win7 only 8GB-Ram and magnetic drives and now have 32GB and SSD´s. So I do not understand why that game is more restrictive on the used Sprites-amount as previously under WIN7..?
Anyway..maybe someone can profit from my findings. Enjoy!
