WHAT KIND OF UPDATE IS THIS?

After the new update, the whole game seems to be lagged out in low specs (Like mine). I usually played at 50-60 fps locked before the update. After the update the game usually just breaks down to 60 - 15 fps. how are you suppose to hit somebody or hit a skill check if the fps drops everytime like this, 60-45, 47-30, 25-15. Idk what the Devs are thinking about the optimization of the game. It's been 4 years since the release of this game, But the game seems to be not well optimized according to its release date. They're bringing new chapters, new killers, new survivors but the optimization of the game is so bad. Now it seems like impossible for me to play this game in my low specs. So if I want to play DBD, I need to have a good specs? After new update, I have to change my specs all the time for DBD? That's Great, Right? They should make the game more optimized, Instead of bringing more Contents. FIX THE GAME FIRST!
