Although I've said "it's up to you" I have a strange relationship with 30fps. In certain games 30 is too uncomfortable - neurologically it's too "slow" when moving to me to register things properly on the screen and I miss objects right in front of me. So in those instances, anything OVER 30 is more comfortable. Of course with sub-standard hardware a lot of games tend to drop 30 and below in places, but as long as, for instance, in Arkham Knight I can get better than 30 most of the time I'm quite happy with this.

But when it comes to film and TV I cannot stand 60. I've grown up with the old PAL standard (approx 30) and anything onscreen faster than this feels unnatural. Sure it's smooth, but it's about as comfortable to me as watching a brown snake slowly slither across my bare feet.

Again, this is personal preference due to my own comfort level and my own modest hardware I own and can afford.

NTSC is 30; PAL is 25. Fun fact: films (almost always 24fps) are just sped up a teeny bit when aired in PAL regions, so they run at 25fps instead. As opposed to NTSC regions, where they use a technique called "3:2 pulldown" to make 24fps fit into 30fps, which is a bit unpleasant to look at. (It involves interlaced fields, where film is alternately transferred to 3 and 2 fields per frame.) That's less of an issue today where you can make TVs run at the correct framerate instead of having to adapt to 25 or 30fps.

Anyway, I find film to be OK when the camera isn't moving much, but otherwise, the resulting mess is kind of annoying. In particular you cannot do pans (especially slow pans where there's no motion blur to speak of) without looking like total crap; the framerate is just too low.

Yeah, sorry. Meant 25. It was a bad morning for me.

For me, the lowest fps I can tolerate is probably 24 fps. That said, it depends on the games that I'm playing, where action games would usually demand higher fps for them to be playable as compared to strategy games.

Lastly, I don't know whether there are other people who feel the same way, but sometimes it gives me this uncomfortable feeling whenever there's this dissonance between the fps in the different games I play. Meaning, if in one game I play at 60 fps while in another I play at 30 fps, I would decrease the fps limit for the former to 30 fps in order to make it the same with the latter (a weird compromise I know, but it just feels uncomfortable for me somewhat).

god ive been there >-<
i used to do 30 for a while, but then the moment i went to 60, i could definitely tell the difference easily. now i could not go back :(

i guess 90-120 would be nice, but not like 144-240...

it depends on the games u play, for shooting games, higher the better,
for story based games, im fine with 60.
but youre always at the mercy of the devs, if they lock the engine to 60 or some shit, then there's no point of discussion, cuz the moment u raise the cap, all hell breaks loose.

I tend to just play at 60fps. It's good enough and doesn't make my GPU go brrrrr...well, not that much anyway.

That could be coil whine, which is normal.

Are we still talking about framerates in 2022?
General rule: the more, the merrier. I wish devs started to optimize to get at least 60 as a standard, the difference between that and 30 is abyssal. You can see it also at higher framerates than 60, but it is imo not as huge as when you get up to 60.
Also, visual quality aside, remember that more frames mean more responsiveness.

Playing on three different screens with the same old gaming laptop.
And adding to what you have already said it is worth using picture enhancers built into external tv screens. Most often is good enough that I can set the resolution to good old 1024x768 without losing any sharpness of the picture or smoothness of textures. That creates a power reserve for higher fps.

Two quotes from the internet
"(...)the resolution of the human eye is 576 megapixels. (...)"
"(...)The human eye can see at around 60 FPS and potentially a little more. Some humans believe they can see up to 240 FPS, and some testing has been done to prove this. Getting humans to see the difference between something that is 60 FPS and 240 FPS should be rather easy. (...)"

Perhaps, but that doesn't mean I like hearing it :P
Its actually the fan that bothers me, really. When it gets to about 2k+ RPM it gets a little loud for my liking. 60 fps tends to keep it under control in most cases, except for some games.
In that case I open up HWmonitor to see what's happening, and if the temperature seems stable I just try to ignore it.

Yes. The "it depends on the type of game" argument makes no sense to me...if you have motion that's intended to be smooth, a low framerate makes it worse regardless of whether it's a shooter or turn-based game. I remember many years ago trying to play Civ IV on an underspecced computer, and while it technically worked, it just wasn't fun to play so I gave up after a couple of games. Later on I tried again when I could run it at 60fps; that made a big difference and I played it for quite a few hours.

The only case I can see where a low framerate would genuinely not have much effect is super old games like the early Ultima entries, where the movement jumps one square at a time and the "animation" is barely existent.

That's false, and contradicts the next bit: Which is still not entirely true, as there is no hard upper limit like "240 fps". Also false. The human eye does not work in fps or megapixels. Here's another internet quote for you:

"Really, though, the megapixel resolution of your eyes is the wrong question. The eye isn't a camera lens, taking snapshots to save in your memory bank. It's more like a detective, collecting clues from your surrounding environment, then taking them back to the brain to put the pieces together and form a complete picture. There's certainly a screen resolution at which our eyes can no longer distinguish pixels — and according to some, it already exists — but when it comes to our daily visual experience, talking in megapixels is way too simple."

120 for me.

I have a 144Hz G-Sync display, and I can assure you: the highest frame rate I can get is the best frame rate there is.
