How so exactly? And in your post you’ve said it all. THE FIRST. First game. FIRST PASS. People are so entitled nowadays...
It’s new tech. There is always a learning curve with these things.
Personally I find DLSS to be awesome - but I have the perfect scenario for it - I game on a native 4k 60hz TV and I want to run the game at Ultra with Ray Tracing ON.
Without DLSS the game runs at 40fps, this gives the Tensor cores enough time to guestimate the missing pixels and so DLSS on gives me a rock solid 60fps.
I'd also tested 60 to 80% render scale - in my scenario DLSS has the same performance as about 65% render scale with the image quality around the same as 80% render, sometimes better. The only issue I have with DLSS is some things like water on walls have odd artifacting, so if 1800p had the same performance I'd use that instead, but it just doesn't, DLSS has much better performance than 1800p.
So while I got lucky, I can feel for others who have a 2080ti on a 1440p screen, they are going to get less value out of their cards because games aren't going to run at a framerate where DLSS is meaningful to them - Nvidia clearly ommitted the fact that DLSS just doesn't work well or at all above 60fps - but yeah, if you're getting 40fps like me and don't want to lower settings, DLSS is your best friend
