Is important to have 60fps or more in shooters? or 40fps is already very good?

If you haven't played a game in 60 fps then you don't need it. It's not until you go back from 60 to 30 that you notice the difference. It's like getting your first glasses only not important :)

To me, I can't tell the difference past 30 FPS. Some can't do under 60 and crazy people can't do under 120. I've heard from people that having more FPS makes the game more reactive to your inputs, so it might matter, but to me no!

Take a look at This
See if you can see a difference. Make your own choice on the matter

I play ultra BF3 with 80-120 fps, a good gaming PC will surpass 40fps on ultra

People tend to say, that human eye cannot capture anything above 30? (too lazy to confirm) fps, but the difference is actually quite huge for me. If you got Counter-Strike (1.6), try to set fps to 100, 60 and 30 and see for yourself.

I Barely hit 30 for most games xD

It’s worth noting that fps can have a big impact on mouse responsiveness, so it’s not so much about how the game looks, and more about how the controls feel.

IMO, as long as it doesn't go below 30fps it'll be fine.

I always mod my drivers to display at only 47.6 FPS.

30 fps is fine for me.

40FPS average is enough for me.

Never needed anything above 30.

i always wanted to know the difference between 60 fps or 100 fps, anything past 60 fps seems overkill and unnecesary to me

It is important to have FPS that doesn't fluctuate too much. It's not low FPS that generates visual lags and freezes, it's abrupt aberrations.

Ideally, your framerate should be the same as your monitor's refresh rate. The majority of monitors are 60Hz, that's why 60fps is standard. If you have a 60Hz monitor and you are running a game at 100fps, visibly there will be no difference however some games might feel faster due to more hardware polls (smoother mouse).

If you have an 120Hz, you want 120 fps. I'm just running stuff ~60 since I'm on such a high res.

I think 60 fps is something just about every game should be doing, especially these days. It is a huge difference over 30 fps. It really delivers a much smoother, and enjoyable, experience. Console games are really bad when it comes to this. Most of the games seem to run at 30 fps. I can tolerate it, but I'm never happy about it.

I love to have my games looking nice, but I will gladly sacrifice (just about) whatever I can to achieve a constant 60 fps in all of my games (unless it looks really awful, like PlanetSide 2 with the render quality all the way down.. Ew =P), with the exception to games like The Elder Scrolls and being heavily modded (Needing at least 30 fps). Those games I just can't go without them looking beautiful. =P

I get headaches if the frame rate is unstable and/or below 60 :)

Before I upgraded my computer I tried to go for at least 45, lower than that got kinda choppy for me. Now I can do over 100 but I don't really notice much difference between that and 60ish.

Skill is what matters, not ridiculously high fps. 30+ fps is fine for most people and 60fps should be more than good enough unless you are being paid to win.

Multiplayer? Yes, because more FPS results in better precision, regardless of your eyes perceiving the extra frames or not. Top tournament players with extreme gaming rigs still play on the lowest settings, and it's because of this reason. You won't see it, but you will most definitely feel it, in multiplayer.

Singleplayer? As long as it's all smooth and playable, enjoyable, no, there shouldn't be need for more than 35, even in shooters.

Done.

You're welcome.

It mostly depends on whether or not you really CARE about it. Of course, running an FPS at 60FPS will allow you to display EVERYTHING that goes on the screen with precision (vsync improves this even further) and smoothness. You'll even see players in tournaments lowering details in games in order to reach the 60FPS mark (or more).

I remember when it was out and hard hitting, Quake III was a great example, the avg player would play with an extreme FOV and easily at around 120FPS, just to be able to react to his opponents.

60FPS is mandatory. I must have smooth gameplay, especially during MP.
