[SOLVED] Help!!! My 1080 TI is performing worse than a 1060 mid gaming until reboot

[Noggs]

I have just built a new PC with the following specs https://uk.pcpartpicker.com/user/Noggs/saved/DdhGGX

My pc is performing perfectly after a fresh boot, then after a while during games it will permanently perform a third less than it should and my frames will drop dramatically with no explanation. The GPU seems to be what is performing terribly even though it's at full load during this bug, I have checked temps during these events and all of it is more than ideal under 60c...

These are the results from 3D MARK after a fresh start at 4.8ghz https://www.3dmark.com/3dm/30228926
and after playing destiny 2 for 20 mins https://www.3dmark.com/3dm/30229449
These are the original results I got when I first built it and clocked it at 5.1GHZ https://www.3dmark.com/3dm/30133766
this seems to have happened after I updated the gpu nvidia driver but I have rolled back to previous nvidia drivers and restored windows, reset bios to defaults and nothing is changing this... Can someone please help me find out what is causing this? I have even tried using two power cables instead of a butterfly one.

Please can someone help me!

Old drivers might be lingering in your system, use DDU to remove them completely.
Download both DDU and the drivers.
Boot in safe mode run DDU and select "Clean and restart"
After rebooting install the nvidia drivers.

I have already done this. Still no change, just tried to use two seperate power cables for the gpu as well instead of the butterfly one and it was worse.

You should post all troubleshooting you have already done.

Have you tried using an older drivers version?

This sounds like your CPU is OC'ed too high. What happens when it's set back to stock values?

(edit: looked at wrong info).

Your score is normal: Here is mine watercooled. https://www.3dmark.com/compare/spy/5016463/spy/2247592

Yeah I have tried an older driver version the last one before the newest one to be specific and the problem persisted. Sorry It's kinda hard to think of all the trouble shooting I've done so far. Done a lot of it.

It's normal to get 40 fps in fortnite with a 1080ti and i7 8700k? lol

IDK your settings, so maybe?. 3DMark score is normal though. If Geforce Experience is changing your settings and running super sampling like 4K downsamping than its possible to get 40fps I would think. I always have to make sure that problem isn't jacking with my games settings.

Would it be changing the settings mid game and then putting them back after a restart though? as the problem only happens after gaming for a while. After a reboot it works smooth as butter, it's almost like it's getting bogged down by something after a while.

Try clearing your command line arguments.

Your system could have a memory leak. Some program is eating all the memory.
