Hey all, this will be a long one because I'll be detailing all of my testing I've tried to see what the problem may be, so I'll stick those parts in spoilers or something. A summary would be that I suspect my i7-7700HQ is throttling the system in games or when dealing with other 3D processes, however I have no idea why it may be doing that, seeing as temps and even %Usage are fine.
I have a Legion Y520 and as of yesterday, overnight, games I used to be able to run fine at well over 100+FPS (namely, Overwatch and Sniper Elite 3 being the two games I did tests on) are now running at sub-40 framerates, regardless of in-game settings. I made no changes to hardware or software, the laptop hasn't been moved from the desk in recent times (it basically acts as a desktop for me), game performance simply plumetted literally overnight, considering the fact that I was playing literally a few hours before booting up Sniper Elite 3 a 2nd time and noticing pathetic performance.
What I've tried so far:
What I've concluded so far:
So, I'm thinking that there's something wrong with the CPU, however Lenovo's own diagnostic software isn't throwing any flags, the temps never rise above 55 Celsius on any of the components and it never even rises above 30% usage. Is this a lost cause that I should just bring into a service center, or is there anything else that I can try myself before going down that route?
EDIT: Here's what happens when I closed out of Overwatch, the CPU jumps back to its usualy clockrate. This is definitely a CPU issue.
Solved! Go to Solution.

Did you update the Graphics drivers recently because there is an issue with latest GPU drivers right now from NVIDIA.
Please roll back the drivers from the Device Manager or
Uninstall the new drivers and install an old version of the drivers from NVIDIA website.
