Dlss option gone missing

Good evening.
As the title suggests… In general options…
The option for Nvidia Dlss is no longer there.
It has been replaced with AMD FSR 2
I have an Nvidia 3090.
What’s going on?

I’ve solved it.
I downloaded and installed the 526.98 driver.
That’s when the dlss option went missing.

So I’ve resorted back to 522.25 driver.
My dlss option has returned.

How bizarre.

User resorted back to 522.25 driver.
