My friend is having an issue in some Bethesda games such as Fallout 3, New Vegas, Skyrim, etc. while he is using a secondary monitor to do other things such as playing music and watching streams etc. His GPU spike up to about 30% usage at most and will hover around 10%, and of course will have less than 10FPS unless on extremely low settings. He contacted Bethesda support and they have recommended to disable the secondary monitor as some Bethesda games do not have multi monitor support and sure enough it fixed the issue entirely. My friend wants to know if there is any way he can run his secondary monitor on games that do not have multi monitor support, such as adding a secondary GPU dedicated to his secondary monitor (I have a GT 520 that he's willing to buy if it fixes the issue). Any other suggestions are welcome.

Do the games perform better in Windowed mode.

Many games just do not get along with multi monitor, but most times it is the second screen that takes the performance hit.

Also try to play with the Nvidia settings for multi-display to see if it helps.

You can always try the other card in the system to see how it reacts.
