On board graphics but getting performance of 1080ti

[froggy6666]

I built a computer for my mate recently. Put a skylake i5 7600k and a strix 1080ti in a asus strix z270-e mobo. Went to his house and he had his monitor plugged into the on board graphics. The thing is, he was getting the performance of the 1080ti, running pubg just fine and running doom on ultra at 200 fps. i dont understand how this worked. i didnt think there was any way that it could work like this, is it because they are both strix products or something like that? anyone who could shed some light on this would be a great help.

What settings?

He should only have been getting the performance of an iGPU since it will use the connected display to render and output.

Are you sure he wasn't messing with you?

it is possible the games are just set to the 1080ti as the device, so it uses the 1080ti for rendering the games

 

while it uses the igpu for monitor output u need to select which gpu u wanna use if u have 2 gpus connected ( in the game device settings )

he doesnt know enough about computers to make that joke, and after dropping $3300 AUD on a computer if it wasnt running right he wouldnt be in the mood to joke around about it. and he was running doom on ultra.

with modern systems they can utilise the gpu through the igpu, as long as tge 1080ti is default

its just what i said the device is just set to the pci-e gpu as standard, which is quite normal

 

if he wants to use the igpu for the games to test somthing he will need to select the device

But dude plug it into the iGPU..u cant get the 1080 ti to render the game if u plug the hdmi cable to iGPU slot can u?

yes u can get it to render on the pci-e gpu while it outputs it to the other gpu where the monitor is connected

Check the 1080ti's usage. If it is taking load properly then let's say PC are dumb proof nowadays.

Been into pc for 6 years and this is the first time i heard something like this is possible.. 

u clearly dont know how gpu rendering works after 6years then, talking about years i been busy with pcs for 18years in that case , years dont mean nothing when it comes to knowledge though

 

its simple

 

u can get a dedicated gpu just for outputting to monitors for example u use a 210gt gpu with 2monitors connected

 

then u have a 1080ti with no monitor connected, if the game supports selecting a device, it will automaticly pick what is the best render option in this case the 1080ti

 

it will choose to render everything using the 1080ti while having the monitor output on the 210gt there

 

how do u think dedicated physx cards work in the first place? u dont need a monitor connected to let a gpu render stuff for u

This works the same way with Crossfire. 

 

I have HDMI and Display Port cables connected to the second video card, and in games where I don't use Crossfire, the primary GPU renders and it is output through the second card just fine.

perhaps he has nvidia optimus or something like lucid installed.

I think I had a similiar situation before, the game ran just fine, a little performance drop but thats it. Some games and app dont support that tho and will render using the iGpu and not the actual gpu

[ingeniousabfool]

Can confirm OP. I once had a dual monitor setup with dedicated GPU and iGPU. Went to test the difference by running games on my iGPU connected monitor and then dedicated GPU connected monitor. Same performance. It was really weird.
