Hi, I figured I'd post this up since I just went through this trip and I hope to spare someone else the grief I just went through.
So I installed all my usual stuff, Elder Scrolls Online, visual studio, office, and when I was done I started up ESO and the NVidia 870 card wasn't working anymore. (ESO plays like crap on the intel graphics, incase anybody was wondering). I messed with the drivers, reinstalled, installed the NVidia beta drivers, intel's etc. I then started over and went through bit by bit and watched to see what failed. Luckily, I kind of suspected hyper-v of being the problem and I started there and sure enough, it was the culprit. (Honestly, feel a little stupid that I didn't suspect it before I started over...but it was a long day at work and I was kind of pissed I had to deal with this at all...so give a guy a break)...
The symptom of this problem, if you come across it, is:
1. Nvidia control panel crashes on start
2. Games obviously slow
3. Desktop right click menu doesn't have NVidia option anymore.
Solution: Uninstall hyper-v. If you really need hyper v...think azure, or amazon, or just use another server like I'm going to have to do. If somebody knows how to get around thi
I hope this helps someone.

eek, I think I am right there with you. I installed win 8.1 pro and then vs2013. Same problem, how do you uninstall hyper-v?
-
Add remove programs and turn off windows features. Just uncheck hyper-v. It will reboot and you should be golden. I think its the windows 8 phone SDK that does it since it needs it.
-
Hmm. Until now, I didn't even know there was a standalone version of Hyper-V.
-
Yeah comes with 8.1 pro and 2012 r2. Its very useful and the gen 2 stuff is nice. Use it all time for development.
-
Oh, and fair warning about restoring the laptop... once you push restore, it restores. Wipes everything out and there are no options or confirmations like 'are you sure?'... it just 'does'.... just a heads up. Probably should create a thread for that..
-
ok, I found out. It is a turn features on/off windows option to disable hyper-v. I turned that off, rebooted and things are back to normal. I am extremely happy to have saw your original post. I had uninstalled, reinstalled drivers including latest beta from NVidia. Was about to consider full system restore which would have been pain. Anyway your post was much appreciated!
Now we just need to figure out how hyper-v can coexist with NVidia. otherwise it would be major hassle to turn it on to work (writing windows phone apps) and then off for fun and games. -
I'm glad to have helped, I only wish I figured it out before doing the restore.... but I was so irritated from waiting a month and a half and having to deal with this that I 'rage' restored it.

Bring up a cmd prompt with administrator Privileges- (or Create a cmd script with the below line)
To turn off Hyper-V
bcdedit /set hypervisorlaunchtype off
To turn on Hyper-V
bcdedit /set hypervisorlaunchtype auto
Requires a reboot but allows you to run the Windows Phone emulator then go back to gaming mode later.
If anyone researches a more updated Optimus driver, or GPU driver that allows Optimus to work with Hyper-V, please post! -
So hyper-v installs itself? Is that what happened?
-
This is weird. I just installed Visual Studio 2013 - the whole thing, including Windows Phone 8 SDK -, and even installed the XNA Game Studio 4 thingie that I use in some solutions, and I haven't experienced this problem.
I am using the nvidia 337.50 beta drivers, though. I don't know if that has anything to do with anything. -
-
Hmm... it's not showing in Windows Features. Maybe I have it disabled in the BIOS, heh.
-
there isn't an option in the bios. I think you only get hyper-v with 8.1 Pro so I'm guessing you didn't upgrade to pro.

Does disabling Hyper V improve performance in gaming?
It's a mixed bag out there some say yes, some no .
I don't think I will ever use it anyway.
Any quick guide on how to disable? -
-
Note to those with this problem. Latest Nvidia driver resolves this, no more need to disable/enable.
