FPS DROP FIX???

i sent 5 or more reports to bhvr that either got declined or ignored where i was talking about getting fps drops that got so bad after singularity came to the game and then it came with even worse drops plus stuttering when the new event came this month. Ive reinstalled the game, updated drivers, verified files, changed config files, restarted and rebooted everything yet its still happening and i see so many ppl talking about this but the devs dont even acknowledge it or say theyll sort it out til the ingame menu options come so please, anyone for once, is there a way to finally fix this problem with dbd?????

cuz this is literally the only game where poor performance is so frequent every single time a patch drops, ive never had any issues like this with my other games cuz they all ran so smooth and clean, i ran re4 remake in high to medium settings and not a single issue and its sad cuz that game came out super recently that onbviously had better graphics and then when i play dbd now, a game thats 7 years old with OK graphics that you can even play on low end pcs, it still runs TERRIBLE and i have high end pc. i cant even hit my skill checks, move my camera around when i loop, i cant even play killer in peace without the game dropping below 30 frames and i play on low/medium graphics. also why have these ingame menu options with fps, vsync etc. not been implemented from the day the game was made and WHY are the devs declining and closing forum posts about fps issues???? it makes no sense like how are we suppose to enjoy the chapters you drop every 3 months if the game is literally unplayable???
