it's quite noticeable. But not really as important as many make it out to be (multiplayer excluded).

The importance of 60 fps is exaggerated for sure and often mistakenly referred to as responsiveness which it isn't.

Responsiveness is based on three things: how fast you can smash a button, speed of electricity and how fast the moves in your game are programmed.

You can do as many moves as possible even with just 10 fps, but the presentation of those moves looks chopped because the naked eye starts to detect 24 fps and over as natural movement.

I wonder why we don't complain about frames per second in movies? :P

I prefer having both good graphics and 60fps. I always try to balance the best IQ and performance regardless of setup (PC). That said some games rely so heavily on atmosphere (Metro Last Light) that Id rather play them at 30fps+motion blur than at 60fps and ridiculously toned down atmospheric effects.

If it was, people wouldn't be playing console games or most PC gamer wouldn't be gaming on their current PCs.

There's not really a definitive answer to that question. As with most other technical variables, how important 60fps is depends on the person you're asking. Some people put a tremendous amount of value in specifics at the cost of everything else, while others prefer various different balance combinations. In general though i'd say that most people have a preference, but the absence of it doesn't stop them enjoy a game (e.g. good IQ and a stable 30fps tend to be my preferences for a console game, but the lack of both didn't stop TLOU being my favorite game in 2013).

As for why PC gamers are more likely to 'bash' 30fps, that's because a) it's a platform that naturally attracts those that are more likely to prefer 60fps over 30fps in general, and b) to many 30fps feels worse on PC that it does on consoles (which compounds the previous general preference). It's worth noting though that those that actively go around mocking console games for being 30fps (in earnest) tend to be part of a minority.

I've played many games at 30FPS be it driveclub or gta 5 and I don't notice the difference when compared to 60fps. And I'm glad too because if I become someone who analysis resolution or framerate like it's the most important thing I'll enjoy gaming less.

To me, it is important, but not "really that important". I think 30 fps is perfectly acceptable and sometimes it might even make a game look better (I can't quite explain why, tho. Maybe it is because of the motion speed, or blur, idk. It just feels more "moviesh", I think.)

What I do think is important is resolution and effects, specially anti-aliasing. If some texture pops up, it's noticeable of bad quality, or if you can see some really bad edges, that's what really bothers me, like if the beauty of the game is stained.

I guess it is important for FPS games tho (guess, because I haven't played many of them in 30fps), but for pure accuracy concerns, I pressume.

So, from me, it's a no. 30 fps minimum, tho, ofc.

It is important, but really depends from game itself.

I'd actually rather be able to run the game at 60 and 1080p. But allowed to lower everything else. I disable shadows in games. And not care. So I can keep the FPS up. The graphics being top of the line, I don't need. I'd prefer average. Like Fallout 4 (ignoring performance issues the game has for a second). To keep both going. Though anything higher (4K 120 FPS etc.), I don't care about either. 1080 and 60 are my sweet spot.

It's sort of like when Blu-ray came out; people who had DVD's said it was fine with DVD but after experiencing 1080p images, DVD's felt like a downer to watch. If you play all your games on a big TV and at a fair distance in 30fps; it likely won't matter, if you enjoy smoother images and game up close on a smaller display and with a much higher degree of detail and effects; it really, really matters and frame rates are essential to the overall experience. I turn off post-processing effects or lower the resolution in order to get better frame rates (or, I used to, my new rig can murder any game at max with great frame rates).

I guess the answer is; it depends.
