Massive deviation in 3D Mark score - 11700k/3080ti

[Merrith]

Hello all! New to the forums here, I am seeking a resolve! I generally keep up with the health and optimization of my PC and try to eek out as much performance without doing anything too drastic. With that said, I went from an average and consistent 30k 3D mark score to 20k. There are no modifications or changes that I can think of that would contribute to this steep deviation from the norm. I noticed GPU temperature changes during load or while running games very recently that prompted me to run my performance test and boy... here are some images.

I'm not certain what to look for to revert this score. Some elucidation would be much appreciated. Thanks.

So obviously something has changed.
But without knowing what changes you made, we can't really suggest what needs to be reverted.
(device driver version, cooling, fans speeds, OS patches, power plan settings, monitor resolutions, G-Sync, driver settings, etc..)
