Question Performance plunges after Driver Update

[Fire-Wire]

Hello, I will try to synthetize as best as I can. All was perfect, but in an impulse I updated the Nvidia driver to the latest and restarted the PC. When it was back up, all heavier games were significantly slower and performing way below expectations, for no apparent reason. Lighter apps are still functioning normaly, as far as I can tell, and benchmarks (such as userbenchmark) shows nothing wrong.

Things I did so far and bore no fruits:

• DDU'd and tried other 7 drivers.
• Switched RAM slots and changed RAM sticks.
• Formatted (via windows restoration tool).
• Messed with energy settings.
• Verified file integrity and reinstalled said games.
• Messed with graphical configuration in said games.

Games tested (that were performing brilliantly before the update)

• No man's sky
• Assassin's creed Odyssey
• Monster Hunter World
• Black Desert

My system:

GPU: gtx 1060 6Gb
RAM: 2x8Gb ddr4
CPU: i7 7700k
PSU: Corsair 650W

Obs: I didn't have any meaningful restore points. Yes, I know, I'm stupid, lesson learned.

sure the new driver didn't turn on some features?

sure the new driver didn't turn on some features?

As I said, even if the driver was the culprit, I DDU'd several times and installed 7 different drivers - nothing changed.

I formatted twice, as well, and the problem persists.

then check cpu/gpu temp and usage, make sure it not hardware issue.

So, I dismantled my PC inside out and assembled it again. It seems like it did it. I don't exatcly know what, but all seems to be fine now.

Thanks for the help
