…It's universally accepted and tested as a fantastic piece of technology. Just make sure about couple of things:

DLSS works ONLY on Nvidia RTX series of cards. (So if you have AMD card or Nvidia non RTX card – DLSS won't work!!)
DLSS has different quality options – It's rule of thumb to put balanced when playing at 4k and quality when playing at 1440p.
DLSS 2.3 – The newest version of DLSS is so good that it can produce image equal to native. So if you're seeing ghosting/blur etc. it's most likely a bug and might not even be connected to DLSS

DLSS was designed around resolutions 1440p/4k. You can still use it at 1080p but expect image quality decrease.

DLSS is GPU bound so CPU heavy settings won't matter. (So you won't see FPS boost in those cases)

That's pretty much it.
And again… Sorry to all people shouting at BSG about "This piece of sh** DLSS!" but I'm gonna trust my own eyes and proffesional testing that proved DLSS is a hell of a feature and pretty much industry standard at this point, then some redditors… I aleady saw someone bashing BSG for DLSS because he couldnt turn it on… on AMD card… Yeah, let that sink in.
