the last days I have drops of fps for 1 or 2 seconds that is so annoying, someone else had it too? I ask some of my friends and they have the same problem too
what platform? If xbox then it's not a new thing at all
It could be your resolution settings, your PC itself, or an optimization error with your game. Also, have you tried verifying the integrity of your files? You can do this by going to DBD in your game library, right clicking on Dead By Daylight, go down to the end of the drop down and click properties, go to the local files tab, and than click the last option to "verify the integrity of your game files".
It's not uncommon to get FPS drops because of bad internet, since the lag from a bad connection can cause this as well. But if your PC is fine, your internet is fine, and you verified the integrity of your files... Than I don't know what the issue is personally. If you can't find the answer here, than you can try and ask about it in the Technical Issues sub-forum. I'll link it below at the end of this comment.
If you only experience this sometimes than that's nothing new if your PC isn't THAT bad but not the greatest. If it's on certain maps like Ormond than that's normal... Since the snow effect will drop your FPS sometimes. But besides that, if it's a BIG issue than you can try asking in the Technical Issues sub-forum if nobody can help you here. The forum users in that sub-forum would be more than happy to assist you with your problem.
I did everything, even I had reset my pc and reinstalled the game, but the problem still, so I stress tested my GPU and CPU and it was also fine. I dont know why I have this issue.. I had it since 2 days
I don't know what to tell you unfortunately.
You did all the common fixes AND stress tested both your GPU and CPU. It might be because of your connection to Dedicated Servers OR DBD as a whole on your computer. I'd advise you to go to the Technical Issues sub-forum I linked above to see if they can help, they're more experienced than I am with these kind of questions. If that fails, you can try contacting support as a last resort to square the issue away. I can't guarantee that either of those options will fix your issue, but it's worth a try!
