Diablo Death animation skip + Diablo disappear

When Diablo (CS) dies, as the first frame of his death animation starts, he suddendly just dissapears, also no corpse shows up. Possibly related to VFX light quality? It set to “high”. First time this is happening. Always worked. Not reproducible. Can anyone confirm?

This has happened to me today and i think that the problem was setting the game to high priority in task manager and also putting the pc to ultimate power plan.After i switched to balanced power plan and didn’t changed the priority of the game to high that is after leaving the game to normal priority the animation came back.Hope this helps.Also the animation might skip if your weapon deals froze damage and this leads to vaporizing of diablo at the end the reason why there is no corspe left after his death.
