Oh boy, I don’t own a console and I used to think the same when many people said this. But its not, you just get used to it. And I experienced firsthand it few weeks back when I played CODBOCO & TLOU2 at my cousins’ on a PS4. And TLOU2 had many Post Processing effects going on, heavy motion blur, Film grain and all. And before that, I played witcher 3 on 40-60 FPS on my laptop and difference was quite apparent at first, latency was high, moving camera in bright areas making my head hurt.
The thing is it feels smoother because of many other reasons than above, you are not tinkering with the settings every 5 minute to get the desired framerate, you are not looking at Stats constantly when playing. If you forget about these things, it makes games more enjoyable even at lower framerates. After few hours I just got used to it, my mind just played tricks and filled the gaps.
But I can agree with you with games that are launched on PC have stuttering, so it doesn’t matter what the framerate it, its 30 or 300. If the game is stuttering you will feel it. And that is the case with TLOU1 on PC for example.
I just finished RDR2 at 42 FPS locked, and it did drop into lower 30s at times. But I didn’t keep the stats on everytime and didn’t feel any immersion breaking lags and all and experienced the best game ever.
With your case of GTAV, I heard they have messed up with optimisations on ps4 with latest updates so that could be the issue.
