Just a quick query about this as its either briefly discussed in old threads or I cant find the exact answer.

I realise that this allows the GPU/Game to render a higher resolution than the screen can display and then scales it down to 1080p/whatever is native. I also understand it will never look as good as 4k (obviously).

But in terms of GPU/overall PC stress, how does this work in comparison to a native 4k display?

Does it stress the rig less due to the fact that it is still displaying 1080p, more because not only does it have to render 4k it then needs to use a bit of extra processing power to rescale it afterward; or is it no different in terms of stress to running the same game on a native display with no VSR?(providing the games other settings are the same).

Could I say use VSR to test how my rig would deal with higher native resolutions before potentially blowing money on a wasted 2 or 4k monitor?

Also, is there any point in having AA on at all while using VSR seeing as it is basically SSAA on steroids anyway?

Got to say it looks fantastic even with my 32" stretching 1080p far too much, not to mention improvements in colour and just general image quality.
 
It will stress the GPU very slightly more than if you had a native 4K or whatever virtual resolution as you have to render the game at the higher res then apply a scaling filter but the filter is only a very small performance hit - usually less than 1% lower performance than if you were actually running the higher resolution.
 
I'd like to run 1440p on my 1080p monitor but it throws all the windows out of place on my second and third monitors when i fire up a game. Does look great without AA though. Not sure if my third monitor being at 1680x1050 is the reason for my shifting browser, Steam etc windows are moved, will see what happens when i get a new monitor in the next week or so, will be all 3 at 1080p :)

With multiple monitors do i need to use VSR on all of them to prevent the issue i am having?
 
Ah right that's interesting, surprised my rig is actually handling 4K and ultra settings with no AA then, even if the games I'm testing it with are getting on a bit (Crysis 3, Metro redux)

May at least go for a 1440p monitor then so I can get more out of this. And if all else fails I am waiting to see how affordable a Ryzen upgrade will be.

Also @mybrains even on a single 1080p display VSR messes windows up a bit due to the fact everything is too small to read and the slider to change proportions in windows is blacked out while using VSR
 
I suspect with multiple monitors it suddenly sees what it thinks it a large display in the mix and not much you can do about that short of using a 3rd party program maybe.
