As someone who learnt about this public 40fps love just a few minutes, I'd like to add that this was something I had noticed myself years ago. 40fps feels "smooth" and closer to 60fps, than 25/30fps for some reason. Unfortunately my graphics card struggled but that's a different story.
What are people doing that they have like a 3080 on a 12700 and can barely hit 60fps??
(Using geforce now on a MacBook hooked up to an external monitor).
BG3 is very smooth. Cities Skylines 2 stutters. Starfield was okay. Talos Principle 2 is laggy. Cyberpunk is laggy.
Normally I don't care about graphics all that much, so I'll usually turn the details down to medium or even low. But these days DLSS is so good that's less necessary.
Yes I need a new laptop *frustration*
