One issue with NVIDIA's DSR is that DLDSR and DSR look different thus require different smoothness values, yet they share the same slider. As a result anytime this program launches a title I set to 1620p (2.25x DLDSR) it's too sharp, or 2160p (4.00x DSR) it's too blurry, so I have to manually change it, defeating the purpose of this app if you're someone switching between more than two resolutions.

I've tried developing my own script doing this automatically in the past, and it worked but some games crashed with my method unfortunately (I used auto hotkey to program it). The way my script worked is it would change the smoothness % by modifying the registry data, and at the same time would switch to the intended resolution while restarting the display driver. Reason why is because the smoothness % doesn't seem to update unless I did that last step, but it causes a lot of current games I was on to crash. Otherwise it would've worked well.
