Quadro played games well, Windows updated, now not so much

[mhrazor1]

This all began with me wanting to play games on my new laptop. For some reason the laptop wouldn't switch between integrated and dedicated graphics for games or any program, regardless of my settings in the Nvidia Control Panel. What ended up fixing that was disabling the Intel graphics from Device Manager and disabling "Switchable Graphics" from the BIOS. Everything was fine and dandy and this thing was playing games like a champ. Killing Floor 2 was running easily above 60 FPS at Ultra.

Then I ran a Windows update. Not like an 8 to 10 update. Just an update for 10.

Now even not very intensive games run like garbage. Something like SUPERHOT, which has practically no textures, averages ~12 FPS, even in the menu screen. The weird thing is that this problem has persisted through multiple installs of Windows 10. The same problem persists with a clean install of Windows, and the 3 different variations of drivers I've tried for the Quadro. This happens regardless of my combinations of Nvidia settings, Windows performance settings, and BIOS settings.

I am at my wit's end.
Any suggestions are appreciated.

Did you update your Nvidia drivers after the Windows update? Just a suggestion, I really have no clue if it isn't that.

Are you 100% sure it isn't running on the iGPU now? because that is what it sounds like
