Rome 2 DEI Crash

Hey guys I am having issues with Rome 2 using the DEI mod. The game is constantly crashing. Especially during large battles, sieges etc. but also randomly sometimes. I have tried several solutions but nothing seems to work.

Do you have any possible suggestions? My PC Isn't a toaster either. It can comfortably run the game at Ultra graphics while maintaining fps. Even so I have put the settings at the lowest possible and the crashes, even if fewer keep happening and they are really messing with my campaign experience.
