Well there is an impact for sure:
- I get 20 fps during hordes now.
- Random lags of 0.1-2s
- Phantom swings
- Speech of all types from behind sounds like it comes out of a cave.
I want to note that the overall performance has never increased in the entire lifespan of Vermintide 2 on my system no matter what. You only broke things and fixed them again.
