Huge frame drops

[lfonixl]

my rig: gtx 1080, 16gb ram, cpu intel i7 4790 3.60( temps are fine)
I have this problem for weeks now, i was playing everything was fine turn of the pc next day turn on to play and boom huge frame drops on every game for example rainbow 6 i use to have betwen 90 140 fps on very high now i have 50 to 70 fps , rise of the tomb raider 60 to 90 now 27 to 48 fps, hitman is unplayable 10 to 30 when im lucky the witcher use to have 60 to 90 now 20 to 50fps.... what the hell is going on?
what i tried: reset pc, clean the hardware, made a new task to dump memory cache, went to regestry and change gamedvr enable from 0 to 1 and the value from 0 to 1, nvidia panel change the physx from recommended to gtx 1080 and image seetings from quality to performance.
Don't know what else to do need help boys and girls.

1. I don't see your operating system in the OP.

2. If you reset the system, now you have to reinstall all device drivers all over again, as well as all Windows updates all over again.

3. Check for conflicting software, and yes, even if you have had the same software for all the time before this started happening :

I would start there.

EDIT....

4. What is the refresh rate of your display ? A counter telling you that you are getting 140 FPS on a display that is only capable of rendering at 60 Hz is not actually 140 FPS. There are some custom Nvidia settings that can somewhat get around this, but a 60 Hz display, for example, cannot render at 140 FPS normally.

I have a 60hz monitor, i know 144 fps on a 60hz monitor is not really 144 but i always played with high fps and it felt very smooth now 60 fps doesn't feel like 60 everything was fine until i t turn it off and turn on (i have install all drivers and windows updates, windows 10)

dont change randoms ettings if you ahve no idea what it does. Physix should always be on Recommended. There games that perform better when CPU does it and leaves mroe resourcess of the GPu for actually rendering frames.
Also dont mess with the registry. tehre is nothing suefull for you to do there despite the possibility of breaking things.

tehre also other thing to take into account than merely your CPU temperature. Things liek drivers, OS updates, viruses, malware, background application ... just to mention a few.
