RTX Video Super Resolution does indeed scale up the image to whatever you set it to.
But by doing so it applies heavy blur so you actually lose all the details of the video.
Try to compare if it looks better or worse with it ON/OFF.
I recommend to disable it. It just adds extra pixels for SVP to interpolate.
You don't need RTX VSR. For increasing video clarity just download a sharpening filter:

and put it in "C:\Program Files (x86)\SVP 4\mpv64" folder:
Then enable it with following line in mpv.conf:
glsl-shaders="~~/shaders/adaptive-sharpen.glsl"
and also add
profile=gpu-hq
if your system can support it so when you go fullscreen it will resize the video keeping it sharp.
