Yes but I consider that one as fine and not too low. Everything below 30fps is actually too low for me 

30fps is the bare minimum for acceptable gameplay... and no suttering, frame pacing, etc. case in point of recent games I would normally have played that I skipped because of performance: - Bloodborne (I bought this one, could not play more than 30minutes of it) - FF XV demo, I got in a few minutes and did not bother anymore, I could not stand it...  I can play most 30fps titles, but I honestly would take a hit on any graphical setting to get 60fps in them, Driveclub would be AMAZING at 60fps, Far Cry 4 would have been much more interresting, I'd kill for a ps4 NEO patch of Uncharted 4 that let me play the SP campaign at 60fps... so on and so forth!

if you want to be technical about it, 16 is the lowest level where motion can be viewed clearly, 24 is optimized for movies and 30 for games. 60 fps is used to define more accurate motion and helps during fast paced action games and sporting events.

as for me personally, around 22 is the lowest i can stand before turning down the video settings. just to be safe I aim for around 40 fps consistently

Recorded images with adapted, clear-cut and static layers cannot be compared to real-time rendering which responds to controller and directional input by a user in interactive environments. Especially if you're sitting up close, as is the case with a PC monitor for example. 24fps on my 32" display at my current resolution would be simply terrible. I don't think it's uneducated to appreciate higher frame rates, if anything, the more casual consumer cares a lot less about this and the ones who prefer higher frame rates are usually the more tech savvy gamers.

I wanna hear from more of the 34 people so far who voted 15fps.

So you're saying 20fps is just fine to you? Teach me the secret of your ocular resilience! XD

In most media, 12fps works as a bare minimum (some animation gets away with less). Games require much higher rates, depending on how important reaction time is. Turn based RPGS can typically be fairly low. Platforming, fighting, and shooting should really be as close to 60fps as possible.

Locked framerates are preferable, but a little variation is okay if it is seldom and allows the overall game to perform at a much higher rate. Example: 60fps with rare dips into the mid-to-low 50s is preferable to 30fps locked for most games.

After MCC, I can't play Halo at 30 fps anymore. Night and day experience.

The screen tearing on every frame of the X1 version, that is amazing. You know for me I'd honestly consider torn frames to be far worse than a low frame rate, as long as the game is responsive and playable I'll not head to digital foundry or have a cry about it. We had a laugh playing through the Broforce port 3 player local co-op on the ps4 I would say that hit single figures at times but still was a enjoyable game, again an issue which did make it far harder than frame rate was a graphical bug with a monsters texture missing, that led to some very annoying deaths but framerate.... not gonna tear up about that too much.

anything below 30.

25 maybe.

I can kinda tolerate framerate between 20-30fps, but nothing below that.
