Windows 10: Latest update / Nvidia issue

Hi pros! Been a while since my last post, got another weird issue I can't figure out, I'd be really grateful for any help!
Big update a few days ago (W10 obvs) - since then I'm having major issues with my Nvidea GPU. It shows in devman and says the device is working properly, but when I try to open the Nvidea control panel I get an error saying "You aren't currently using a display connected to an NVidea GPU" and the option to use this device in other programs (ex, OBS) isn't there. This means I can't capture my screen. OBS has never worked using the Intel onboard graphics, I always just disable that in devman and then display capture would work perfectly in OBS.

What I've done so far -
Uninstall both Intel and Nvidea devices, including their drivers and reinstall the latest of both
Manually disable Intel onboard graphics to force use of Nvidea GPU
Uninstall and reinstall OBS
Ran OBS as Admin

The only video capture device showing in OBS is my webcam, and as mentioned the Nvidea software is claiming I'm not using that device so won't open the CP.

The reason I'm posting here and not to OBS or Nvidea Q&A is because everything worked fine before the last W10 update.

Quick note, the Nvidea GPU is actually working (I know because my screen always behaved differently when using that to the onboard Intel GPU) but for some reason it's not detectible in other programs any more, not even the Nvidea CP itself.

Can anyone help me out here?!

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.
