Non SLI Graphics Card Performance Gain

[Juan Gutierrez]

So I already know that if you use two mismatched gpus it wont help you render games any faster. But if I install another graphics card and then set my non gaming programs no use that card, will that offload enough from the cpu integrated graphics and the main gpu high performance graphics to consider using a last gen card for applications like discord, chrome/browsers, and really any program that uses video card power that in excess might produce a positive result. 
 

I dont know if I should try this with my 2080ti and 1080 with a 750w power supply. 
 

I would use the windows feature that lets me pick which gpu to run the programs on

Using a second GPU for a second monitor won't increase your performance. Driving another monitor takes almost no resources and it barely affects your fps. You can use it. But it won't change a whole lot.

If you can figure out how to make another card render those other programs and not have the main card do it, by all mean Id love to that that and the fps not change.

It wouldnt be for a second monitor. It would solely be to offload chrome and other applications from using the resources of the main card. Or perhaps to even run another game at the same time in the background. Running one game in one card and another in the other.

By all means, if you know how to do that, Id love to see it. Without using virtual machine. A lot of time and effort for no gain. Test fps with discord on and off and there wont be anything. And if youre the type to watch videos and still use chrome while gaming that's an issue within itself. Think its best to take the supposed fps loss.

I think ill try it tonight. Basically just go to display settings, graphics settings and then where it has Graphics Performance preference you could pick which application would use which graphics card.

Yep, just verify usage while doing so. Youll be surprised.

So i checked and the biggest usage change was when I ran a program with dedicated use of this card. I loaded up world of warcraft on my 1080 and black desert online on my 2080 ti. I was able to run both with decent refresh rates considering the load. I had a steady 65 fps in a main city in wow and around 110 with upscale in bdo/ 80 without upscale. 
 

If I didnt manually change the program to work on the 1080 the default 2080ti gpu was chosen.
