I have an RTX 3060 that I bought about two years ago. Until recently I only had a 1080p 75Hz monitor, so I could play pretty much anything on max settings.
Then I decided to treat myself to a 1440p 180Hz monitor, which has been amazing. Obviously this is a lot more GPU intensive, so I have had to turn down some settings. Then I decided to try out FSR. I'm on Linux and gaming mostly through Proton, so it was as easy as adding a launch command.
Holy crap. Elden ring (admittedly not a very intensive game) went from a choppy 50 fps on high settings and medium ray tracing, to a smooth 60 fps on maxed out settings and high ray tracing with FSR Quality. And I can't even tell the difference from the upscaling! I'm super impressed and can't wait to try out FSR 2 and DLSS now!
DLSS is extremely noticeable to me at stronger levels. I usually turn it on but keep it set to “quality” instead of “performance”. It’s still slightly noticeable but not that bad at that setting.
Stronger DLSS just looks like blurry mush to me.
