So i created a sub rog character, and i noticed that my fps drops to 0 or 1-2 fps when i hit an enemy, it didn't really bother me. But when i started having more skills to use it started to be really annoying. Is it just a bug ? Because it never happened before.
I use to have some similar problem where out of no where when i hit something with mele atack game would freeze for 1-3 sec very regularly and not just once but multiple times when i fixed it.
Try deleting cache folder but don't think it will help.
What i ended up doing was deleting whole game and download it again.Then put that game on seperated external hardrive as copy for when ever my game would break's so i can replace it since anything ealse i tried didn't work.
Could be that you have too much of a potato PC/laptop in 21for a 2008 game ^^.
