I had made many workarounds the last years every time I installed Sacred 2. I uninstalled Sacred 2 often because the game crashed after (10 min with PhysX) or 30-60 min (without PhysX )
I hate it.^^ Every Sacred player know this feeling^^
New install , search and many many many workarounds later I found the sacred ^^memory cleaner.
This man is so awesome he solved this f... problem. The game starts and runs and runs and runs no crash anymore, because the programm delete the memory all 5 min^^ AWESOME YEEEEHHHAAA
Here is the link.
Have fun . I have to play now ^^
