Is 30FPS Enough

I would not recommend 30fps in any shooter type game. 60 is almost a must to be viable. aka, live longer

Even 24 Fps is fine although that won't hold true in Esport titles such as CSGO or LoL there should be at least 60Fps & at an optimal 120Fps with a 120Hz display

As someone else said, once you go 60+ you never go back.
Sky is the limit (if you have the Hz to spare)!

In console 30fps is a normal But ofc 60 should be better.

Personally no. I have a 100Hz monitor and I don't think i'll ever be able to go hack. It makes so much difference to even 60fps

I Wouldnt recommend playing with only 30. It looks laggy in motions, try to get more

30 FPS way way behind 60 FPS. 60 FPS is way better. The higher FPS the better.

The more FPS the better smoother gameplay, obviously.

Ever since I switched from console to PC, I can never go back to 30fps.

I've been playing with 60FPS for about 2 years now.
I limited some games to 30FPS just to see how I used to play and oh my god is my reaction priceless. I can't imagine ever going back to 30FPS gaming. I also hunt down 60FPS YouTube videos.
