Windows 10 App Scaling

[Koxicain]

Hey Guys, 

Im currently trying to figure out how im able to scale a specific application 100-XXX%. 
I run a 1080p Monitor but i scale the game to a higher resolution and then downscaling this to 1080. 
Now when i do this the UI of the game will get smaller so im trying to figure out how i can scale the Game only and not my desktop aswell. 

When using the Windows Scaling Feature it fixes the UI problem but when im going to scale the game to 8k the windows scaling will make my desktop
icons and taskbar HUGE and i just want it to be normal size but scaling the application only. 

I have looked through the internet and tried to finde some solutions but so far come up empty handed. 

I currently have it working with 1440p to 1080p which works perfectly. It makes the game look amazing therefor i wanted to try even craziere sizes.

Games nowadays typically have a "rendering resolution" setting that does this without having to do anything on Windows side.
