RTX SuperResolution BUG: Good before 1860 but BAD with 1875_Mega

Hi,
The function RTX SuperResolution is good before 1860 with MPC-Use MPC Render-Use D3D11-Request Super Resolution For <= 1080p,
But it is BAD with 1875_Mega. Not sure if same things happened with other versions between 1860~1875. On windows 11, sure.
You can know it is BAD by looking into Nvidia control panel. If it is working, Alt+tab and you would see control panel says status: active. If I use 1875 no matter what I tried it is Inactive.
I am pretty sure it is not only me, because the same thing happened when I tried to install K-lite Codec Mega in net cafe on two different PCs with NVIDIA Card, and plus my PC it is three.
Several other options are tried, but nothing gonna work if you use 1875_Mega. And when I installed back to 1860 Version, everything is fine.
Could anybody try that and give me some feedback to see if it is true? Thanks! I would stick to 1860 for now.

You are probably playing 10bit video. Only 8bit is properly supported by RTX VSR.

IT IS NOT A BUG !

It is intentionally not used anymore for 10bit because in several cases you will get bad quality with messed up colors.

But of course you can be stubborn and think you know better because it worked for you with a couple of files. But the developers do not care. They know better. So good luck being stuck on the old version FOREVER due to stubbornness.
