How do I correctly implement DLSS, DLAA, and NIS?

Hello, I’m trying to implement DLSS the correct way in my options menu.

The image is very blurry when enabling DLAA, so there must be something wrong. Also, how do I implement NIS sharpening?

Should there be a check beforehand to see if DLSS is supported?

Thank you!

for sharpening you can use execute console command or there is BP node for that assuming you have NIS plugin installed and enabled
