New Work Laptop w/ Intel HD Graphics and NVIDIA Quadro...

Just got a new laptop at work and I'm now seeing that it has both Intel HD Graphics 4600 and Nvidia Quadro K3100M enabled. As far as desktops go I have always always outright disabled my onboard graphics from within the BIOS if I have a discrete GPU. Unfortunately it appears that my BIOS doesn't have this option... odd. I also don't have permissions to disable it from within device manager. So far I've read about driver upgrade conflicts, but are there any other potential issues operating with both enabled? How do I even know which one is driving everything?

EDIT: Looks like does some sort of BS graphics switching to save battery. There is no clear way to shut it off completely, but I did find a way to launch apps using the Nvidia graphics and also to setup a list of apps to always use the Nvidia graphics by default.

Yeah, its a system that basically uses the integrated graphics for low power stuff and the discrete to do other things that require more video card juice. My laptop is like that as well, not sure which cards though. I think the best you can do is to enable performance mode or go through specific applications and say that you want to use the nvidia card instead of the integrated.

I believe that is controlled by Optimus. Not a good system, but you should be able to just right click the program you are going to run and tell it to use integrated graphics. There is a master list in the NVidia tray to change the default for programs.

I usually try to go the other way to force the card to work instead of the integrated. Sadly, you never really know what is running, even the task bar that is supposed to display the usage is not correct in many cases.

Yeah looks like there is no good way to control. Yes you can manually set it and yes you can manually launch it by right clicking. Not really happy about this since the system is so darn big I would never use it as a portable anyway. Seems to just add confusion. Seeing plenty of issues from people online where their games are running off integrated graphics.

Yes, it is an annoyance. I remember having to perform a number of registry hacks to get Shadow of Mordor to actually run using my card rather than integrated. That was the only one I recall having that problem.

Many times with older games off GoG or something I will specifically have to force it to use the integrated graphics or it will stutter like mad.

Optimus is nearly pointless in my experience. These machines and processors eat so much power that having to use a more powerful card wouldn't be a bad thing. Forcing graphics onto an already overworked processor only ruins the experience. Battery life will be horrid no matter what.
