How do I utilize second grapgics card?

[escamilla117]

I've got an alienware 18, Windows 8.1 64 bit, and fallout 4 doesn't use the second graphics card. What can I do so that the games I play can use that second graphics card? Drivers are up to date

You need to enable SLI, 30 seconds of googling gave me this: http://www.computerhope.com/issues/ch001167.htm

If it doesn't work for reply to this post and I will help as best I can.

Fallout 4 doesn't support SLI yet (if it ever will). You need to use Alternate Frame Rendering or a decent profile (but none of them work as well).

Launch Nvidia Control Panel--> Manage 3D Settings --> Program Settings --> Select Fallout 4 (Fallout4.exe)-->change SLI Rendering Mode to: Force Alternate Frame Rendering 2. it will warn you against changing this setting, just hit okay and save.

Depending on the card this can create more problems than its worth and may or may not give you a good boost in performance. Try it at your own peril.

Edit: Never-mind. Apparently they added support for it in 359.06. Must've missed that patch note haha. So simply enabling SLI in your Nvidia control panel should be enough.
