Win 10 2 different GPU question

[Bubib5]

Hi guys, new here, and i have a problem i would like to solve, and hope you all can help.

 

So, i have a rig that i use for gaming only, the specs are : I7-8700k, asus hero X mobo, 32gbs ddr4 3200mhz gskill, samsung m.2 ssd for win10, samsung ssd for my flight sim, and 3 different hdds for scenery, and everything else. I run an 4k curved predator Z35 as my main monitor, and an 21 AOC as my secondary.

 

When the system was built it originaly had an strix 1070ti, and a few weeks ago i got my hands on an strix 1080ti very cheap, so i stick both of them in, my primary monitor is connected on the 1080ti, and my secondary is on the 1070ti, the problem i need to solve is that my system uses the 1080ti for everything, the 1070ti is not being used at all, what i would like is to use the 1070ti for chrome, and all that i run when gaming, or whatever is displayed on the secondary monitor which is connected to the 1070ti.

 

Is that possibile at all, or should i just sell the 1070ti, as i has no use at all to me being in the same system as the 1080ti?

 

Sorry for the long post, and thanks in advance for the answers!

 

WIth kind regards

That would make literally no difference to your ingame performance, in fact I'd just sell the 1070ti - it's just drawing power from the wall for no reason.

 

The reason you see no usage on the 1070ti is that chrome barely uses the gpu anyway.

It doesnt work that way, sell the 1070 ti

Not possible.

And what about this then? I will try this out and report back!

 

Sorry for rezing a dead thread, but there's a big caveat that wasn't mentioned and is very relevant if you're running 2 different GPUs.

 

Windows, specifically Windows applications generally do not care how many different GPUs you have. Say you have Monitor 2 with a 750 and Monitor 1 with a 1070. Chrome is going to push all GPU accelerated content to the primary display's GPU regardless of which monitor a window is on. What this means is your 750 is sitting there not being utilized. All the work is still going to your 1070.

 

Ok, so how do you get that 2nd GPU to actually do some work? Good question:

 

Make the monitor your 2nd GPU is plugged into your primary display in the Nvidia control panel. So with a 1070/750 combo, you want to set the monitor your 750 is plugged into as your primary. This will cause all GPU-accelerated programs, i.e. Chrome, Twitch, Batlenet, to use your 750. To get your games to utilize your 1070 just load it up, set it to Monitor 2 that your 1070 is plugged into and it'll drive off your 1070 while the remainder of your desktop programs will use your 750. Make sure to restart said game after you set it to the correct monitor. Works regardless of fullscreen, or windowed.

 

From my experience, you're looking at a 10-15 FPS improvement. You can confirm all this via Task Manager Performance and the NVCP GPU systray icon

I can succesfully confirm that these instructions work like a charm, i got my 1070ti being used for all of the programs i run besides my flight sim on my second monitor, currently set as main monitor, and my flight sim being the only program using my 1080ti!

 

So it can be done
